In general, waste heat cannot directly generate electricity. The waste heat must be sent to a waste heat boiler to convert the water into steam. The steam is used to drive the steam turbine to drive the generator to produce electricity. The amount of heat source to be used for low temperature waste heat depends on the boiler which cannot generate electricity directly. We tested that the waste heat generator group of Tianrui Zhengzhou Cement Plant uses the waste heat from the cement production process, which reaches more than 300 degrees.
The waste thermal energy generation boiler has the following functions of high and low pressure boilers:
1. The boiler plays the role of reducing the temperature of the whole flue gas, which can ensure the normal operation of the dust collection equipment in thee system and achieve low temperatures and environmentally friendly smoke emissions.
2. The boiler uses waste heat to generate steam at high temperature and high pressure, and is integrally combined with the supplementary combustion boiler to drive the turbine and generator to generate electricity, thereby providing energy to all of the cement. production system equipment.
3. The boiler has a certain self-dusting function, and the separated dust can be recycled and used to achieve the multi-purpose function of a machine.
4. It is helpful to reduce the energy consumption of the whole system and achieve full energy utilization.
