Zink Körner cuts energy consumption in galvanizing by 15 percent

Efficient furnaces for hot dip galvanizing

Zink Körner cuts energy consumption in galvanizing by 15 percent

A galvanizing furnace for cable support systems

The new RECU-CHANNEL recuperative heat exchanger system may achieve energy savings of more than 15 percent in batch-parts, wire and small-parts galvanizing. In typical batch-parts galvanizing plants, this may result in approx. 30,000 euros saved on natural gas costs every year.

For galvanizing at temperatures between 450 and 460 °C, Zink Körner has developed its new RECU-TEC hot dip galvanizing technology, which allows the input energy to be recovered directly in the furnace. These furnaces are equipped with a steel tank and natural-gas fired flat flame burners.

Innovative recuperation technology

The new RECU-CHANNEL recuperative heat exchanger system heats the kettle very uniformly and exactly to the required temperatures. Operation of the furnace requires more than 15 percent less energy than traditional systems. Thus, more than 30,000 euros per year can be saved on natural gas costs, for example, in case of a batch galvanizing plant with an average through-put rate of 6 tons per hour.

While in conventional systems without RECU-CHANNEL technology the waste gas collects at the top, RECU-CHANNEL systems suck the waste gas from below in a controlled way allowing the waste gas to flow downwards past the outside surface of the kettle wall. Thus the waste gas transfers to the lower part of the tank exactly that amount of energy that is required for the process.

The channels are arranged at both long sides of the furnace extending along their complete length. Thus the waste gas travels long distances, giving it more time for the heat transfer. Using the residual heat in the RECU-CHANNEL to preheat the combustion air leads to a further increase in furnace efficiency.

The result: While the waste gas temperature of furnaces without RECU-TEC usually reaches 550 °C or more, the waste gas temperatures of the new furnaces are always below 400 °C, even in case of full load operation. This is a clear indication that the input energy is extremely efficiently used.

Highly efficient burner technology

Zink Körner has developed the modulated KÖRNER FL 15/80 flat flame burners specifically for the heating of steel kettles. These burners feed just as much energy to the galvanizing furnace as necessary at any point in time.

Unlike intermittent burners, they operate with a combustion air ratio of only 1.10 – hence with much less surplus air than usual. Their efficiency is 10 to 20 percent higher and gas consumption correspondingly lower than that achievable by burners operating with a ratio of, let“s say, 1.20.

Additionally, the modulating operation avoids short-term consumption peaks. This saves on gas procurement costs as the gas suppliers calculate their provision fees based on the peak load of the furnace.

Each of the diffuser plates of the new burners is supported by three rods fix mounted to the burner port. This arrangement achieves constant pressure conditions which allow the flame to be adjusted with utmost precision. For the user this provides the benefits of ideal combustion ratios and minimal gas consumption.

The burners are installed along the long sides of the furnace at two thirds of the furnace height (from the bottom). At that position, the heat requirement is highest due to the heat loss at the bath level.

New patenting furnace saves ten percent on energy

Resource-saving wire production: New measuring technique enables control of furnace atmosphere.

New patenting furnace saves ten percent on energy

Patenting furnace – side view

At Wire 2014, Wire Körner will exhibit the new series of directly heated patenting furnaces fitted with automatic furnace atmosphere control and burner with heat recuperation. With these new energy-saving furnaces, Wire Körner further expands its range of efficient and eco-friendly heat treatment plants for wire. Based on his good experience with the furnace, a German customer has already ordered an extension to the existing unit.

The first unit of this new furnace generation has been in operation for two years. Designed for a throughput of 2,000 t per hour, it processes wire in diameters from 1.5 to 5.5 mm. The plant expansion is expected to be commissioned in April 2014.

By implementing a wide array of innovative features, Wire Körner has increased the efficiency of patenting furnaces for wire and achieved savings on energy consumption of some eight to ten percent compared to conventional furnaces. The very first furnace of this new generation has already been in production for more than two years.

With an innovative sensor, Wire Körner has for the first time realized a system for controlling the furnace atmosphere. Via the furnace control system the air/combustion gas ratio is exactly set within a specified range. The high control precision and stability of the gas/air ratio makes the new furnaces superior to Pre Mix systems. In addition to the savings on energy, controlling the air/gas ratio keeps NOx emissions low and prevents decarburization of the wire. The furnace temperature is adjusted with a precision of +/- 2 °C.

A central recuperator installed in the waste gas duct preheats the combustion air for the high-speed burners to 200 – 250 °C, while reducing the waste gas temperature at the stack from 600 °C to 400 – 500 °C. Already in the preheating zone Wire Körner exploits the thermal energy of the waste gas to heat up the wire entering the furnace. This reduces the energy demand for preheating.

In contrast to previously used burners, the high-speed burners employed by Wire Körner can be adjusted in several steps. This ensures that the burners consume exactly the amount of energy they need, not more.
Wire Körner has brought down heat losses via the furnace wall by optimizing the layout of the wall, among others by means of insulating ceramic fibers. An additional coating ensures a long service life of the furnace wall even under conditions of high CO contents and high flow velocities. An additional, 2.5-cm-thick Microtherm® insulating layer behind the refractory brick lining brings down heat losses even further.

The furnace is directly heated. The heat is transferred into the wire by convection, at flow velocities of up to 120 m/s. This provides much better energy efficiency than heating by radiation.

Zink Körner increases efficiency by 10 percent

Efficient furnaces for batch galvanizing: Zink Körner is the only supplier of furnaces that use burners specifically developed for batch galvanizing.

Zink Körner increases efficiency by 10 percent

A recently installed furnace for a throughput of 12 t/h is equipped with twelve 180 kW flat flame burners.

Zink Körner offers a wide gamut of design features to reduce energy consumption in batch galvanizing. For example, burners specifically developed for batch galvanizing give Zink Körner furnaces efficiencies of 75 percent – 5 to 10 percent more than attained in conventional plants. For a typical furnace, this translates into annual cost savings of about 25,000 euros.

Infinitely adjustable flat flame burners, a wall construction that allows only little heat transfer and a novel reflecting refractory coating lead to a distinct increase in energy efficiency. By offering plant concepts that integrate all these features, Zink Körner is constantly strengthening its position as trendsetter in energy-efficient furnace technology.

In spring 2011, Zink Körner commissioned a new facility for batch galvanizing at Salavatmetall in the Russian Republic of Bashkortostan. In that facility, Zink Körner implemented the full line of economically and ecologically useful technical features.

The plant galvanizes above all polygonal poles, transmission towers and crash barriers. It is designed for a production rate of up to 12 t/h. The galvanizing tank is 13 m long, 1.6 m wide and 3 m deep. The furnace is equipped with 12 flat flame burners of type FL 20/50, which Zink Körner specially developed for batch galvanizing. While using the relatively low-cost natural gas as fuel, these burners afford the benefit of uniform and careful heating – which in the past was only achievable by electrically heated furnaces.

The burners achieve an efficiency of 75 percent. Clear evidence of the efficient energy use is the low flue gas temperature. In a recently implemented project incorporating a furnace with a throughput rate of 10 t/h, the flue gas temperature is only 507 °C. As a comparison: in conventional plants the flue gas temperature is often higher than 625 °C.

Compared with plants using impulse-mode burners, Zink Körner furnaces using flat flame burners achieve impressive energy savings, for example, about 500,000 kWh in a facility with a throughput rate between 10 and 15 t/h operated in two shifts for 4,000 hours per year. At a price of 5 cents per kWh, this results in cost savings of 25,000 euros per year.

Unlike the burners commonly used in the past, these innovative burners operate in a modulating mode. They are infinitely adjustable within a range of 1:10. Through this, the power is being constantly adjusted to match the furnace throughput. Consequently, the furnace consumes exactly the amount of energy required in the specific moment. This regulating mode also avoids abrupt temperature changes, which may cause excessive stresses in the galvanizing tank structure.

In addition to these features, Zink Körner implements further efficiency-enhancing measures. Diffusor plates mounted on the burners direct the gas flow along the inner furnace wall. This produces a combination of radiant and convective heat, which has the effect that the thermal output of the furnaces into the galvanizing tank is high at relatively low mean temperatures. The multi-layer, 300-mm-thick insulation reduces heat loss and the innovative ceramic coating applied to the fibrous insulation additionally reflects the radiant heat towards the interior of the furnace.

Fluidized-bed technology gaining ground

Resource-saving heat treatment of wire: Already two furnaces of this technology in the commissioning phase

Fluidized-bed technology gaining ground

The new-generation fluidized-bed furnaces have no distributor pipes or tiles.

The new fluidized-bed furnaces for the heat treatment of wire, which Wire Körner presented for the first time at Wire 2010, have convinced wire producers: The first two plants of this kind will be operational before Wire 2012 opens its doors. These innovative furnaces, which have no distributor pipes or tiles, afford the benefit of lower energy consumption by up to 15 percent and low investment and maintenance costs. Additionally, premixing of the combustion gas outside the furnace guarantees uniform temperature distribution and reduced emissions.

The first two orders were placed right after Wire Körner had introduced the new fluidized-bed furnace at Wire in 2010. The first furnace is currently being commissioned at a customer“s site in Turkey. The second one is being installed in Ecuador. At Wire 2012, Wire Körner will present first reports on practical experience with this new technology.

The patent-pending furnaces dispense with distributor elements as typically used in conventional designs. This eliminates a number of components which used to be considered indispensible in the past, as, for example, the fairly complex and expensive distributor tiles, perforated distribution pipes or stand-by blowers.

Peter Kordt, Managing Owner of Wire Körner, expects significant cost reductions for his customers: „The simplicity of the design has obviously convinced our customers. The new technology saves up to 15 percent of energy compared to conventional furnaces. Also the savings on maintenance will be significant, because what does not exist does not need to be serviced or maintained.“

The absence of the distributor equipment markedly reduces flow resistance of the combustion gas inside the furnace. Hence the required blower capacity can be lower than that of competing designs by about 20 percent. Not only the smaller blower unit but also the overall simplified furnace design will markedly reduce capital costs. Additionally, the new design no longer requires a stand-by blower, which was necessary in the past to provide cooling air to cool the steel structures in the event of a power failure.

As the combustion gas is premixed outside the furnace, the new design achieves a uniform fuel-air mixing ratio throughout the fluidized bed and a homogeneous temperature distribution over the width and length. This results in higher combustion efficiency and lower emissions of unburned hydrocarbons.

Through carefully customized control algorithms, efficiency is maximized at all loads. This saves up to 15 percent energy. For a typically sized furnace, this means more than 7,000 euros per year saved on energy.
