Factors affecting Thermal efficiency of pressure Module Boiler
Due to the consideration of environmental protection conditions, many countries are basically carrying out the work of changing coal to gas. The selection of modular boilers largely avoids the contamination of ash accumulation, and at the same time, the discharge of dangerous gases such as nitrogen oxides has been clamped down. Thermal efficiency is an important rule to measure the thermal efficiency of modular boiler. Next, let us study a number of factors of thermal efficiency of pressure module boiler.
After the inquiry of the relevant personnel, the heat loss of the module boiler mainly includes these two parts: the full proportion of combustion air is unreasonable and the heat loss of smoke emission is unreasonable. Reducing the heat loss of smoke emission can be installed at the end of the module boiler, or the FGR boiler with more advanced function can be selected.
The unreasonable proportion of combustion air is not in accordance with the standard analysis: the ejector burners are used in the general module boiler, resulting in the air-fuel ratio can not be maneuvered. Some of the modular boilers use mechanical air supply burners, which cause the unreasonable air-fuel ratio to be unreasonable in the following aspects: the unreasonable air-fuel ratio mainly includes two cases: when oxygen exceeds the standard, Countless excess cold air can be heated, resulting in the increase of energy consumption cost of the module boiler and the decrease of the thermal efficiency of the module boiler. When oxygen is irregular, incomplete combustion will occur, and the thermal efficiency of modular boiler will decrease.
