Working principle: tube type waste heat boiler is: the heat of the flue gas water saturated water. Inside the casing pipe with heat, the mixture of water vaporization produced along the riser to drum, for steam-water separation; saturated water drum through the lower header pipe into decline sleeve type heat pipe assembly, evenly into the jacket for natural circulation. Drum water level within the maintenance shall be borne by the water supply system.
The structure of the boiler and features: the device is composed of three parts: heat pipe steam generator, steam (water separator), circular tube. Heat pipe steam generator is a steam generating device, the sleeve pipe type heat pipe as heat transfer components. Due to the characteristics of the heat pipe itself that heating and circulation and the heat source of the device (flue gas) apart, isothermal heat exchange element has excellent, has the ability to resist the corrosive gas dew point corrosion. Steam and water circulating system heat the unique structure of the casing pipe and perfect. The boiler has the following characteristics:
1, the heat transfer from flue gas into the water completely by the heat pipe element, water, steam is heated indirectly, and flue gas in different space;
2, the system of heat pipe element are mutually independent, single or a plurality of damage generally do not affect the operation of the system;
3, because of unidirectional heat conduction of heat pipe, heat transfer only from flue gas to the water, and not by the water, the steam to the flue gas side;Any external power is not
4, heat transfer process.
