Coal-fired boilers, biomass boilers and other environmentally friendly boilers need to be equipped with dust collectors to reduce emissions. Bag dust collectors are common boiler dust collectors. How to choose? The hot water boiler can be used for central heating in shopping malls, residential areas, etc. Why is it necessary to configure a heat exchanger when it is used for high-rise heating?

1. Selection method of boiler bag filter

  The choice of bag filter depends on what the biomass boiler burns. The dust collector is connected to the boiler chimney through the flue. Different biomass fuels have different bag filter configurations. The boiler burns wood and burns more biomass particles. Bigger, more Mars. For example, if a 4 ton boiler burns biomass particles, a dust collector with 240 cloth bags is sufficient. If a 4 ton boiler burns wood, a dust collector with 300 cloth bags may be required. Therefore, the specific configuration of the bag filter depends on the fuel used.

2. The function of plate heat exchanger for high-rise heating of hot water boiler

  If the heating area of 100,000 square meters is huge, the amount of water lost every day may reach more than 2,000 tons. It will directly lead to the paralysis of the entire heating boiler system. If there are heat exchange stations, the primary network does not lose water, and the secondary network has 20 heat exchange stations. On average, each small heating system only loses 100 tons of water, which is within the acceptable range.

  Also, 100,000 square meters, from the boiler room to the farthest building, sometimes can reach a distance of more than 5 kilometers. This will result in near-heat and far-cold. In relatively nearby areas, the room temperature can reach above 25 degrees, but the water at the end does not circulate at all, and the room temperature can only reach about 13 degrees. The heat exchange method can solve this problem. For each small heat exchange station, the heating radius is less than 1 km, and the heating effect is relatively uniform.

  There are also pressure difference problems, boiler maintenance problems (the water of the heat exchanger boiler and the water of the radiator will not contact), heating load problems and so on.

The selection method of the boiler bag filter and the function of the plate heat exchanger are introduced above. If you have more boiler-related questions, you can consult our company. If you need to design a boiler selection plan, you need to put forward specific use requirements and local environmental protection requirements, our company will customize the boiler plan for you.
