kedel pellet boiler cost
Air scaling coefficient α (not on predetermined criteria)? A: According to GB / T16157-1996 "emissions from stationary sources of particulate matter and gaseous pollutants measured sampling methods", SO2 emission concentration of kedel pellet boiler cost should be converted into the measured excess air coefficient α = 1.8 at a concentration of emission.
Boilers and furnaces distinction and deaerator Optional: heat transfer station and the kedel pellet boiler cost room, the difference between them, what is? Optional deaerator on the boilers, which usually is? And, boilers and furnaces distinguish between simple right? These issues are on the boiler, and that is very important and basic, so below, immediately give a specific answer, so that we learn through to clear, rather than a smattering. 1. heat transfer stations and boiler room, the difference between them is mainly what? The difference between the boiler room and the heat transfer station, if summarizing, then, there are mainly the following, is: one difference: heat transfer station, which is to convert the boiler room to the production of hot water a user may direct use of hot water, its temperature is lower than 100 degrees Celsius. And high temperature hot water generated by the boiler room, is higher than 100 degrees Celsius. Difference between the two: the boiler room for the production, the heat transfer station is as a transit station, so they used the device, is not the same, that can not be mixed. 2. Optional boiler deaerator, should be how to choose? Deaerator, which has a head type and there is no points of the first type. In the boiler, which is typically the first type of this kind of choose, without selecting the type of this kind without a head. However, if it is a large boiler plants, because it is more than 1000t / h, then, it is to adopt non-tower-type deaerator in order to meet the demand. And, on this point, we should have a clear understanding, you can not go wrong.
We can think of, to a few decades, the party will soon be implemented in the next few years: the digital workshop, open-plan offices, model worker Innovation Studio, garden chemical industry park, the hotel of the staff quarters, a model customer panorama kedel pellet boiler cost room , honor VR, VR ...... these artisans will be demonstrated by the fast square panoramic VR atlas, people will be able to feel the mobile phone side, the gas field fast boiler open mind and strength! 20 years of precipitation technology, more than 100 national patents, more than ten national honor certificate, the State Ministry of energy saving recommended products, domestic boiler industry being the only nationally recognized "academician workstation", under the aura, is the party who constantly fast pursuit and creation. Fast boiler, condensing gas boiler leader!
Boiler water circulation 1. theoretical value in the form of warm district heating system, a large flow of a low-temperature radiation heating, heating kedel pellet boiler cost circulating water than conventional radiator heating system should be large, according to cell location and distribution of building floor height parameter, district heating pattern taken by the secondary heat exchanger system, to meet the overall cell mass and the heating effect. 2. The heating system of resistance along the pressure loss, the pressure loss of local resistance and other factors, and equipment to pipelines and fittings specification data calculating determined. When considering circulating pump selection. 3. In the secondary heat exchanger unit circulating pump selection should consider the flow rate, the pipe system resistance and lift the design parameters.
