Therefore, in addition to supplementary firing, all the waste heat boilers have the same or similar structure. The new coking waste heat boiler, a highly efficient heat transfer, separation of functions furnace soot, and its new compact, …
Brief introduction: Coking plant produces large amounts of 550～900℃ coking waste gas during its production, to further utilize the waste heat we have developed the coking waste heat recovery boiler to improve energy utilization and protect environment. Efficient recycle of waste gas
Waste Heat Boiler - an overview | ScienceDirect Topics
188.8.131.52.2.3 Energy Recovery. An ironmaking plant consists of blast furnace, coking plant, sintering, and/or pelletizing plant. Both coking plant and blast furnace generate significant amount of extra heat in the form of COG and blast furnace-top gas. Both gases are secondary fuels, and are utilized in most cases internally (within ironmaking
Burner head. Typical arrangement of a waste heat boiler (illustrated as a water- tube boiler with The catalytic oxidation of ammonia is a base reaction for the production of Final assembly of a LaMont type boiler means of LaMont nozzles. This is provided with a …
This new patent of waste heat boiler for the waste gas of coke has the function of high efficiency heat transfer, two –level of soot separation in the boiler. it achieves the advanced level in China because of its compacted structures, novel structure, low cost, small floor area, environment protection and …
Feb 15, 2019 · Fig 2 Cut-away drawing of a Jewell-Thompson heat recovery oven . The coking of the input coal takes place by direct heating from the oven crown and by indirect heating from the refractory floor. The whole system is being operated under negative (sub atmospheric) pressure. The time of coking in Jewell-Thomson oven is around 48 hours.
CDQ Waste Heat Boiler. CDQ waste heat boiler is used by coking industry, the inert gas is used as a medium to cooling high-temperature coke, the absorbed inert gas is passed to the boiler, and then fed into the coke oven by circulating fan for recycling, to achieve high-temperature waste heat recovery.
Coking Waste Heat Boiler can organically combine the various components of the boiler without the change of their functions, centralize the heating surface, simplify the structure in the coking waste heat boiler and achieve the multi-function composite of the various components. This new patent of waste heat boiler for the waste gas of coke has
The waste heat boilers are widely used for various industries, such as glass industry, coking industry, pyrite-based sulfuric acid product industry, fertilizer plant, chemical industry (methyl alcohol, ethyl alcohol, formaldehyde, synthesis ammonia), cement manufacturing, cogeneration and concentrated heating for carbon rotary kiln, etc.
Jul 23, 2015 · Coking waste heat boiler is installed in the coking furnace back-pass, to recycle the flue gas waste heat and reduce energy consumption. During the process of coking production, the coking plant will produce a lot of waste gas with the temperature of 550~950 degree C.
Combustion for heat generation begins in the boiler burner system and the heat is transferred to the water in the boiler. The boiler produces steam and hot water for industrial process applications. Many boilers use an economizer to preheat the process water before it is fed to the boiler using waste heat from the exhaust gas.
A waste heat boiler uses the heat formed as a byproduct of another process, heat which would normally be wasted, and uses it to create steam. The steam can be used to drive turbines which produce electricity. Alternatively, the boiler can simply be used to heat water or other kinds of fluid. As it recycles some of the energy used, a waste heat
