R & D of General-purpose Software for Boiler Fuel-gas and Air Resistance Calculation

The gas and air resistance calculation is an important part of boiler design. The universal model of the gas and air resistance calculation summarizes the calculation method is presented, the software framework is built up by Object-Oriented and the integration technology with the thermal calculation system is studied. The gas resistance calculation system, calculation methods and software system are improved to be correct and universal by practice, and it is applicable to all kinds of boilers with excellent currency.
