Increased Efficiency: Economizers and condensers are designed to capture and utilize the waste heat from boiler flue gases. This process significantly improves the overall efficiency of the heating system.
Reduced Fuel Consumption: By maximizing heat recovery, these devices lower the amount of fuel needed to reach the desired temperature, leading to substantial fuel savings and reduced operating costs.
Lower Emissions: Improved efficiency translates to less fuel burned, which directly reduces ...
Condensing boilers can achieve up to 98% thermal efficiency, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies over 90% when the return water temperature is at 110 ºF or less; the lower the return water temperature, the higher the efficiency gain.
This is because, under normal circumstances, the exhaust temperature of the boiler cannot completely condense the water in the flue gas, and the difference between the low calorific value and the high calorific value is mainly in the part of the latent heat of vaporization, so the low heat is used. The value is calculated to reflect the true efficiency of the boiler. However, there will be some special circumstances. For example, if the boiler is a condensing boiler, the calculation of the condensed water portion should be calculated using the high calorific value.
