Reasons why condensing gas boilers are more energy-saving than steam boilers07/13/2021
First of all, because the heating temperature of the condensing gas boiler is low, the temperature of the hot water outlet is generally between 110-150 degrees, and the heating is all sensible heat without latent heat. Secondly, the combustion temperature of the condensing gas boiler is low, the exhaust gas temperature is also low, and the loss is small. The third is that the temperature of the hot water sent out is low, and the pipe heat dissipation loss is small. The fourth is that there is no need to continuously discharge sewage and the loss is small. The fifth is that the fuel can be inferior and the fuel cost is low.
Condensing gas boiler-a type of boiler. It is distinguished by medium. In addition, according to the medium, it can be divided into: steam boiler, hot water boiler, steam and water boiler, organic heat carrier boiler. Hot water boilers can also be divided into fuels: coal-fired hot water boilers, oil-fired hot water boilers, gas-fired hot water boilers, and biomass hot water boilers.
According to different fuels, hot water boilers can be divided into electric hot water boilers, oil-fired hot water boilers, gas-fired hot water boilers, coal-fired hot water boilers, etc.; according to whether they are pressurized or not, they can be divided into two types: atmospheric hot water boilers and pressurized hot water boilers , What we usually call "hot water boiler" refers to the atmospheric hot water boiler. Because of its safe operation, most people use this atmospheric hot water boiler for bathing or heating.
Condensing gas boilers are mainly used for heating and bathing. The hot water boiler circulates the hot water in the heat preservation water tank through the hot water circulating pump, and it can heat the hot water in the water tank again and again to achieve the purpose of bathing; the hot water boiler circulates the hot water from the heating pipe through the hot water circulating pump through the radiator (radiator) It can meet people's heating requirements; the hot water boiler and hot water circulating pump cooperate with the heat exchanger to realize the dual functions of bathing and heating.
In the natural circulation hot water boiler, the inlet and outlet water are taken over from the top of the upper drum, and the inlet water is guided by the inlet water distribution pipe to the downcomer to enter the front and side lower headers, and is heated up by the inlet water wall pipe. The front and rear ends of the upper drum are provided with water barriers at the boundary between the descending and rising water flows, and the water barriers only cut off the lower half of the cross section of the drum.
For forced circulation, the inlet water is connected to the lower header at the front end, rising from the front water wall tube to the upper drum (the front water wall downcomer is cancelled at this time), and then transferred to the side water wall tube down tube to the side lower header, and then distributed to the side The water wall tube rises to the upper drum, and then descends from the front row of convection tube bundles to the lower drum. Finally, several processes are detoured between the upper and lower drums and water is discharged from the back end of the upper drum.
