A waste heat boiler refers to a boiler that uses waste heat from various industrial processes, waste materials or waste heat and the heat generated by the combustion of combustible substances to heat water to a certain temperature. Oil-fired boilers, gas-fired boilers, and coal-fired boilers with flue box and flue waste heat recovery are also called waste heat boilers. Waste heat boilers can produce hot water or steam for use in other sections through waste heat recovery.
Due to the particularity of the production system and the waste heat power generation thermal system, the boiler mainly plays the following roles in the entire system:
(1) The boiler plays a role in reducing the temperature of the entire flue gas, can ensure the normal operation of the dust removal equipment in the system, and achieve low-temperature environmentally friendly emission of flue gas.
(2) The boiler uses waste heat to generate high-temperature and high-pressure steam and is integrated with the supplementary combustion boiler to drive the gas turbine and generator to generate electricity, providing power for the entire cement production system equipment.
(3) The boiler has a certain self-cleaning function, and the separated dust can be recycled again to achieve the function of "one machine with multiple uses".
(4) Conducive to reducing the energy consumption of the entire system and making full use of energy.
