■ structural characteristics of waste heat boiler is generally not the fuel, there is no combustion devices, compact layout of heating surface area is small. Waste heat boiler heat mainly metallurgical, mechanical, chemical and other departments of the various kiln exhaust gas, and the internal combustion engine, gas turbine exhaust and so on. The heat source is characterized by a wide range of temperature varied widely, effectively recycling waste heat. Use of waste heat recovery can be greatly reduced business operating costs, emissions fully meet the requirements of environmental protection, but also to make the Earth a blue sky should be a contribution.
■ Our company produces the waste heat boiler is divided into two categories: shell and tube and the flue.
■ shell and tube heat recovery boiler is mainly used for small chemical fertilizer plants, mainly constituted by the tubes and the metal shell of one small-scale waste heat boiler of compact, flexible arrangement of heating surface characteristics, which have needle-shaped tube heating surface tubes, spiral finned tubes, H-finned tubes, the boiler more compact size.
■ flue waste heat boiler is mainly used for sulfuric acid, lime production waste gas utilization, mainly by the drum, the composition of evaporation tubes, arranged flue heating surface forms of water-based device, it has a separate furnace wall and the frame, which is a species of larger waste heat boiler.
