Natural gas steam boiler only up to match the heating should be used, so the user must find the appropriate based on the actual gas boiler heating subject of his or her.
Based on the theory, a lot of natural gas steam boiler of 0.6 MW for 10000 square meters room heat, but, on account of various external and internal factors, gas boiler about will give seven thousand to eight thousand square metres room heating.
Sometimes, the boiler operation conditions are going to be reduced accordingly gas boiler heating part of theoretical value. Boiler will produce scale in operation as well, thereby reducing the thermal efficiency of boiler. Natural gas quality less than it,will reduce the combustion efficiency on the boiler. Reduce boiler outside the condition can even be attributable to the heating area. As an example, within the room warm do not,leading to leakage, heat along with factors will reduce boiler heating area. The weather temperature can also affect the actual part of gas boiler heating, like the Northeast winter colder regions, heating area will likely be a lot less than a few other central city.
The same  2o ton gas heating boiler for sale under different working conditions, inside a different city, under different climate conditions have different heating effect, choice of heating boilers must look at the internal factors and external factors exist, to ensure the gas boiler participate in the biggest role in heating season.
