1、 Users can make choices according to their own economic strength and fuel supply.

2、 Model selection the mode of model selection is mainly to select the thermal power of the combustion engine according to the thermal power rate of the boiler (determined by the combustion engine)

Machine thermal power (redetermined model)

1. Calculation method of burner power: burner power = boiler power / thermal efficiency determines the model of burner and

    Select the pressure and flow suitable for the combustion engine according to the actual needs.

    Gas burner: required gas flow [M3N / h] = (burner power [kwx3.6) / [gas calorific value MJ / M3N]; Fuel burner: demand of fuel flow [kg / h] = (burner power [kW] x3.6) / fuel calorific value [MJ / kg].

2. Valve block selection for gas and dual fuel burners (mainly for gas boilers):

   Use the air valve group selection table to select the valve group with sufficient diameter. Please note that the value of the air valve group selection table is based on the boiler back pressure

   Data when is 0. When selecting the gas valve group, the actual gas pressure must be subtracted from the boiler back pressure to select the valve group. The gas in the gas valve group selection table is natural gas.

3. Check the connection size of the burner, especially the combustion head needs to be suitable for the boiler. The length of the combustion head in the boiler should be 10-20mm from the combustion head to the refractory throat. Check the flame size in the flame size drawing. Please be sure that the flame cannot touch the furnace wall.

The above is all about how to correctly select boiler burners.
