    A higher percentage can be recovered with a Flue Gas Condenser, assuming there is enough cold water to condense all of the flue gas that is available. Therefore, for 'ball parking' purposes, start by comparing boiler input capacity with the need to heat water. For example: consider a 500 hp boiler with a gas input of 20 million BTUs per Hour.Learn More

  • Flue Gas pressure drop - Boiler and Pressure Vessel

    Up to10%cash back · In early days, gas passages in boilers were large. As a result the pressure drop owing to the flow of fluids through these passages was small. So most boilers did not need any external means for moving the fluid through the system. As with an open fire, air was driven through the fuel grate and the boiler furnace simply by the buoyancy force of the hot flue gas. This is callednatural draft.Learn More
