Coal-fired chain grate steam boiler producing 20 tons of water purification materials
As the pollution of water resources becomes more and more serious, emerging water purification materials are slowly being put on the table as an emerging industry and have become very effective materials for treating sewage. From a macro perspective, it can be divided into: water purification activated carbon series, water purification filter element series, water purification filter material series, water purification agent series, and water purification filler series. Today, the editor will introduce to you a coal-fired chain grate steam boiler that produces 20 tons of water purification materials.

2. Coal consumption of 20 tons of coal-fired chain grate steam boiler
From the 20-ton coal-fired steam boiler models introduced above, we can know that there are many models and the pressure can be freely selected. This results in the coal consumption of 20-ton coal-fired chain grate steam boilers not being the same. Calculation formula for coal consumption of coal-fired boilers: boiler coal consumption per hour = boiler thermal power * 3600/coal combustion value/boiler efficiency
The user can roughly calculate the coal consumption of the boiler according to this formula. For example, this SHL20-1.25-AⅡ has a boiler thermal power of 14MW. The calorific value of bituminous coal is generally between 27170 and 37200kj/kg. We take the middle value of 22.3MJ/kg to calculate. The design thermal efficiency of ZBG GroupSHL20-1.25-AⅡ is 80%, then set the formula: 14MW*3600/22.3MJ/80%=2825kg
