Pulp bleaching and papermaking

Pulp bleaching and papermaking: chlorine bleaching is transformed into oxygen enriched bleaching to provide cheap oxygen. Oxygen enriched combustion in sewage treatment can improve the furnace temperature, increase the furnace capacity by 20-40% compared with air, and reduce the fuel consumption by 50%, extending the furnace service life. During oxygen enriched combustion, due to the elimination of most nitrogen, the combustion process is more effective, the amount of flue gas is greatly reduced, and the emission of nitrogen oxides and other harmful substances is greatly reduced, which is conducive to environmental protection. Oxygen is used to support the combustion, and the combustion temperature is high, which can reduce the amount of flue gas and the content of harmful substances generated in the waste combustion process. The heat generated in the waste incineration process can be recycled for heating and power generation. In short, oxygen enriched combustion support can improve productivity, save energy and reduce consumption. Oxygen combustion supporting is also widely used in iron and steel, non-ferrous metallurgy, chemical industry, furnace energy saving, glass and papermaking industries.
