Description

Boiler with waste gas advanced treatment

Technical Field

Background

The boiler is an energy conversion device, the energy input to the boiler comprises chemical energy and electric energy in fuel, and the boiler outputs steam, high-temperature water or an organic heat carrier with certain heat energy. The hot water or steam generated in the boiler can directly provide heat energy for industrial production and people life, and can also be converted into mechanical energy through a steam power device, or the mechanical energy is converted into electric energy through a generator.

The biomass boiler is a boiler using biomass energy such as crop straws, agricultural processing wastes and the like as fuel. Compared with a coal-fired boiler, the biomass boiler has the advantages of low sulfur dioxide and ammonia oxide content in the discharged flue gas, renewability, low pollution, wide distribution, very rich total amount and the like, and can save the energy consumption. However, when biomass fuels such as crop straws and agricultural processing wastes are wet, the fuels can not be combusted sufficiently, a large amount of smoke and dust are generated in the combustion process, the content of sulfur dioxide and ammonia oxide in waste gas is increased, and if the treatment of the smoke and dust cannot be enhanced, the desulfurization and denitrification treatment of the waste gas can be influenced by the large amount of smoke and dust in the waste gas, so that the desulfurization and denitrification treatment effect is reduced, and the waste gas cannot reach the standard and is discharged. In view of this, we propose a boiler with advanced treatment of the exhaust gases.
