Product Description

Waste incineration flue gas processor :

Product Information:

The purification system of waste incineration power plant usually contains semi-dry method deacidification, dry spray,  activated carbon adsorption, bag-type dust remover, wet desulphurization, GGH heat exchanger and SCR denitration process.
The flue gas from the waste incineration power plant, after being deacidified by wet process, has a temperature of 50-70ºC and is in a saturated water state. Direct discharge will corrode the flue channel and chimney and produce white smoke at the chimney outlet.Therefore, it is necessary to use steam or high temperature original flue gas to increase the outlet temperature of deacidified flue gas to be above the acid dew point.From the point of view of energy saving, using high temperature original flue gas to heat the low temperature net flue gas with GGH heat exchanger is the most economic heating method.





According to different working condition and flue gas temperature, we developed various types of heat exchangers used for waste incineration system, including all welded plate heat exchanger and tubular heat exchanger.

All welded plate heat exchanger:



All welded plate heat exchanger takes the all welded plate bundle as heat transfer unit and stainless steel plate with round shape dimple as heat transfer element. By using the regular convex on the plates,the disturbance effect of flue gas is improved, so as to form turbulence with low Re, enhancing heat transfer performance. The plate surface is smooth, not easy to accumulate dust, avoiding energy waste caused by low heat transfer efficiency with high fouling resistance. Seamless welding is adopted between plates to guarantee there is no risk of leaking on the core of equipment.

Non-metallic tubular type heat exchanger:



The tubular heat exchanger adopts the non-metallic tube structure and can bear the low temperature dew point corrosion. Normally the high temperature flue gas enters the heat exchanger and after heat transfer with deacidified flue gas, the temperature can be lowered to be below  120 ºC,and can even achieve 60ºC in the low temperature trigonum. At this time the moisture fog and composition of sulfur in the flue gas coagulated into sulfuric acid,which causes dew point corrosion and has a bad effect on the service life of heat exchanger. While the heat transfer tubes adopted by non-metallic type heat exchanger has higher anti-corrosion performance and can solve the problem of low temperature dew point corrosion, better guaranteeing long term and safe operation of the equipment. The heat transfer tubes can be designed and fabricated into different pressure and stiffness classes according to various users' special request, such as different flows, pressures, cover depths and loading conditions.At the same time, the tubular heat exchanger module is equipped with a protective network to prevent external damage during transportation and installation.
