    For a boiler feed pump controller, the MM 150SMD can be used for the pump controller. It has a snap switch in it (S). For a LWCO, the MM 63M has a No. 2 switch in it and is already a snap switch. Many locations are now forbidding use of mercury type switches for boiler applications.Learn More

  • How to calculate the gas consumption of the gas boilers

    Formula for calculating oil consumption of diesel-fired steam boilers: fuel consumption per hour of oil fired steam boiler = 3600* thermal power / diesel calorific value / boiler efficiency. If it is burning diesel, the fuel consumption per hour is about 132kg. 1 ton diesel steam boiler produces 1 ton steam per hour, so the fuel consumption of a 1 ton diesel boiler is about 70 liters.Learn More
