Thermal power generation generally refers to the use of heat energy generated when combustible materials are burned to heat water, turning the water into high-temperature, high-pressure water vapor, and then using the water vapor to drive the generator to generate electricity. In thermal power generation, the burning materials will produce a large amount of smoke. Gas and flue gas need to be treated with desulfurization, denitrification, dust removal and odor removal to reduce their pollution to the environment.

When the exhaust gas generated by thermal power generation is purified, the existing purification equipment usually uses a single spray equipment for purification.
