The heat is today used for the indoor climate and is delivered by electricity boilers and a waste heat recovery boiler that is installed next to the induration furnace, using hot gases from the furnace to heat water. This work will however assume that one can use the heat from the waste heat recovery boiler to preheat the material stream.
The reverse heat transfer of the sinter cooler produced by the Company makes the temperature of the hot exhaust gas stable and comprehensively improves the quality of the recovered sintered heat, while keeping the hot exhaust gas temperature of all the coolers at 450 ~ 550 ℃, which is about 150 ° C higher than the temperature of the conventional cooler outlet hot exhaust gas.
sintering ﬂue gas and cooler gases into the atmosphere.To make full use of the waste heat in the steel production, we design and develop sinter cooler waste heat boiler to save energy. GENERAL DESCRIPTION: Performance advantages Details Sinter Cooler Waste Heat Boiler
dust content in the off-gas, which can cause problem in the waste-heat boiler. Outokumpu Flash Smelting After a preliminary test in 1946, the first full-scale flash smelting furnace started operation in 1949 at Outokumpu Oy, Harjavalta (Finland). Flash smelting has been the most widely adopted copper matte smelting process since 1970.
This is a waste gas sensible heat recovery system from sinter cooler to generate electric energy. The system is composed of dust collector, waste heat recovery boiler as steam, circulation fan and power generator by steam turbine. The values of cost and effect are obtained from a system configuration of two identical sintering machines, coolers each equipped with waste heat recovery boiler and
Heat exchanger - WikipediaA heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be The word steam generator was regularly used to describe a boiler unit where a hot liquid stream is.
The results show that, the thermal efficiency of ring cooler and waste heat boiler were 26.78% and 45.60%, respectively, the corresponding energy efficiencies were 22.88% and 45.08%, respectively
WASTE HEAT RECOVERY BOILERS - Johnston Boiler
Heat recovery from residual blowdown. About 40% of the energy in boiler blowdown can be recovered through the use of a flash vessel and associated equipment; however, there is scope for further heat recovery from the residual blowdown itself A cooling machine should have a sintering machine, exhaust-heat boiler, cooler, and main stem pipeline.
The heat exchanger is arranged to heat water to be fed to a device, such as waste heat boiler, adapted to be operated with thermal energy recovered from a cooler for cooling the finished sinter discharged from the conveyor, whereby the thermal efficiency of the plant can be much improved.
Following is a typical waste heat recovery application involving operating conditions relating to a Johnston Boiler Company WHR boiler installation. = 187.28 X $3.58/Gal X 5,256 = $3,523,950.00/Year In this example the Johnston Boiler Company waste heat recovery boiler is capable of reducing fuel costs by as much as: $402.00/Hr $9,655.00/Day
A third source of waste water from the open hearth furnace is the blow down from the waste heat boilers, which recover heat from the exit gases and produce by-product steam. If there is a separate water treatment plant to supply make-up for the waste heat boilers, wastes from regeneration of the water treatment system may also constitute one of
Temperature of coke after cooling: < 200°C: Time of coke cooling in chamber: 2.0-2.5 Hr. Temp. of circulating gas before cooling chamber: 170-180°C: Temp. of circulating gas before waste heat boiler: 750-800°C: Pressure of steam generated: 66 ata: Temperature of steam generated: 500°C: Generation of steam / boiler: 25 ton / Hr

An engineering demonstration was carried out for industrial boiler flue gas waste heat and moisture recovery. The steam recovery efficiency reached 40% by achieving good recovery performance. Chen et al. [ 3, 19 ] studied the recovery performance of nanofiltration ceramic membranes of varied pore sizes under different experimental conditions.

The introduction of industrial furnace. Update：Liming. Industrial furnace is in the industrial production, the use of fuel combustion or electrical energy into heat, heat the material or artifacts of thermal equipment. Broadly, the boiler is a kind of industrial furnaces, but people are not used to include it within the scope of the
Those pertaining to cooling technology or waste heat utilization, outside the scope of this report, are not listed. Background on Coal-Fired Boilers In 1980, more than 340 steam electric plants in the U.S. utilized coal for 80% or more of their power generation and had a nameplate capacity >25 MW.
