Why biomass water boilers are more energy efficient than biomass steam boilers

2019-12-13

The first is because the heating temperature of the biomass hot water boiler is low. Generally, the outlet temperature of the hot water is between 110-150 degrees. When heating, all the sensible heat has no latent heat. Secondly, the combustion temperature of the biomass boiler is low, the exhaust temperature is low, and the loss is small. The third is that the temperature of the hot water is low, and the heat loss of the pipeline is small. The fourth is that there is no continuous sewage discharge and the loss is small. Fifth, fuel can be inferior and fuel costs are low.
Biomass hot water boiler is a kind of hot water boiler. It is distinguished by media. In addition, according to the medium, it can be divided into: biomass steam boiler, biomass hot water boiler. Biomass hot water boilers can also be divided into fuels: coal-fired hot water boilers, oil-fired hot water boilers, gas hot water boilers, and biomass hot water boilers.
Biomass hot water boilers can be divided into electric hot water boilers, oil-fired hot water boilers, gas-fired hot water boilers, and coal-fired hot water boilers according to different fuels; they can be divided into atmospheric hot water boilers and pressure hot water boilers according to whether they are under pressure. There are two types of “biomass hot water boilers” that we usually refer to atmospheric biomass hot water boilers. Because of their safe operation, people usually use this kind of atmospheric hot water boilers for bathing or heating.

Biomass hot water boilers are mainly used for heating and bathing. The biomass hot water boiler circulates the hot water in the heat preservation water tank through the hot water circulation pump, and repeatedly heats the hot water in the water tank to achieve the purpose of bathing; the biomass hot water boiler circulates the hot water in the heating pipeline through the hot water circulation pump, through the radiator (Heating fins) can meet people’s heating requirements; biomass hot water boilers and hot water circulation pumps combined with heat exchangers can achieve the dual functions of bathing and heating.

Structural principle
In the natural circulation biomass hot water boiler, the inlet and outlet water are taken over from the top of the upper drum, and the water inlet distribution pipe guides the inlet water to the downcomer and enters the front and side headers. The upper and lower ends of the upper and lower drums are provided with water barriers at the boundary between the descending and rising water streams, and the water barriers only block the lower half of the cross section of the drum.
For forced circulation, the inlet water enters the front lower header, rises from the front water-cooled wall pipe to the upper pot (the front water-cooled wall down pipe is canceled at this time), then turns into the side water-cooled wall down pipe to the side lower header, and then distributes into the side The water-cooled wall tube rises to the upper pot, and then descends from the front row of convection tube bundles to the lower pot. Finally, there are several detours between the upper and lower pots, and water is discharged from the rear end of the upper pot. Forced circulation boilers do not have economizers.
