Industrial production uses various furnaces, such as heating furnace, converter, reverberatory furnace, fluidized bed roaster, rotary kiln, etc. These furnaces all consume a large amount of fuel. Their thermal efficiency is very low, generally only about 30%, while the heat taken away by high-temperature flue gas, high-temperature slag, high-temperature products, etc. is up to 40-60%. The available waste heat accounts for about one-third of fuel consumption in metallurgy, and more than 15% in machinery, glass, paper making, etc. use Waste heat boiler The method of recovering waste heat has been widely used in various industrial sectors in the past 20 years.
Waste heat boiler refers to a boiler that heats water to a certain working medium by using the waste heat of waste gas, waste or liquid waste in various industrial processes and the heat generated by the combustion of combustible materials.
Waste heat is the heat discharged without being fully utilized in industrial production. It belongs to secondary energy and is the product of conversion of primary energy and combustible materials.
Waste heat boiler mainly has the following characteristics:
1. Adopt module structure design, reasonable layout and superior performance;
2. The boiler can adapt to gas turbines with different fuels and meet different waste heat utilization needs;
3. The boiler can meet the requirements of frequent startup and shutdown of gas turbine, with strong peak shaving capacity and fast startup;
4. The boiler adopts a multi-layer protective plate thermal insulation structure, with strong air tightness and simple structure;
5. The boiler components are assembled and delivered, which is convenient for installation and short in cycle.
