High temperature flue gas waste heat boiler design and manufacturing by waste heat boiler supplier Zhongjie Equipment

Description :

　　The conditions that should be met when designing a waste heat boiler

　　1. Smoke side parameters:

　　Smoke volume (standard or operating conditions), smoke inlet temperature, smoke composition, smoke dust content, smoke side pressure (positive or negative), boiler smoke side system resistance

　　2. Boiler parameters:

　　Boiler rated evaporation capacity, boiler rated steam pressure, boiler rated steam temperature, boiler exhaust gas temperature

　　3. Other parameters:

　　The industry to which the main flue gas system belongs, system process description, boiler installation form, boiler structural form, meteorological parameters of the boiler installation site, or other special requirements.

　　The role of waste heat boiler in production system

　　Due to the particularity of production systems and waste heat power generation thermal systems, boilers mainly play the following roles in the entire system:

　　a) The boiler plays a role in reducing the overall temperature of the flue gas, ensuring the normal operation of the dust removal equipment in the system and achieving low-temperature and environmentally friendly emission of flue gas;

　　b) The boiler uses waste heat to generate high-temperature and high-pressure steam, which is then combined with a supplementary combustion boiler to drive the gas turbine and generator to generate electricity, providing power for the entire cement production system equipment;

　　c) The boiler has a certain self dust removal function, and the separated dust can be recycled and reused, achieving the function of "one machine for multiple uses".

　　d) Beneficial for reducing the energy consumption of the entire system and achieving full utilization of energy.

　　Types of waste heat boilers

　　The main types of waste heat boilers include: sintering machine waste heat boiler, three waste mixed combustion furnace and blowing gas waste heat boiler, cement kiln waste heat boiler, steel waste heat boiler, hazardous waste waste waste heat boiler, garbage incineration waste heat boiler, coking waste heat boiler, non-ferrous metal smelting waste heat boiler, sulfuric acid waste heat boiler, ore blast furnace industry waste heat boiler, glass kiln waste heat boiler, dry quenching waste heat boiler, carbon kiln waste heat boiler, gas steam turbine waste heat boiler, steelmaking waste heat boiler, etc.

　　Cement kiln waste heat boiler

　　The pure low-temperature waste heat boiler is an efficient boiler that mainly uses the low-temperature waste heat flue gas discharged from the preheater kiln head clinker cooler and kiln tail preheater at 250 ℃~400 ℃ to generate micro superheated steam. At the same time, the micro superheated steam is used to drive a low parameter steam turbine to do work and generate electricity. The overall structure of this type of boiler adopts a vertical layout form, which has significant characteristics such as flexible layout, small footprint, low infrastructure investment, low air leakage, and low steel consumption, and is highly favored by users. The use of low-temperature waste gas heat for power generation is an effective way to save energy, reduce consumption, and achieve comprehensive resource utilization. It can not only reduce cement production costs, improve enterprise economic benefits, but also enhance enterprise competitiveness, partially alleviate electricity shortages. At the same time, it can reduce exhaust gas temperature and dust concentration, as well as CO2 emissions, greatly reducing air pollution and greenhouse effect on the environment, enabling cement enterprises to achieve resource recycling and clean production.
