How much air volume is required to burn one ton of white ash in a vertical kiln?

Whether a mixed-fired kiln or a gas-fired kiln requires a reasonable air supply, because any fuel combustion must meet three conditions, namely fuel, air (oxygen), and open flame, any one of which is missing The conditions are non-flammable. The amount of air used is calculated based on the oxygen demand of the combustible component of the fuel. If the air supply is not fuel, the fuel will not be sufficient. If the air supply is excessive, the excess air will become a large amount of heat in the flue gas, thus causing an increase and waste of fuel. Its air volume is generally calculated according to the formula: (calculation formula omitted) Its pressure should be calculated based on the different resistances formed by different kiln types and different raw material particle sizes. Generally speaking, the resistance of a shaft kiln can be calculated according to the formula of

40-70 H2O/effective height (m). However, there are differences in the particle size of raw materials and fuels. Therefore, the selection of fans must be based on both theoretical calculations and specific furnace types and actual experience. Only in this way can we have good use effect.
