high efficiency boiler

1200kw gas fired horizontal thermal oil boiler heating system Flame and high temperature smoke produced by complete burning of fuel (coal, oil, gas, etc.) exchange heat with organic heat transfer media in the pipe by radiative transfer and convection transfer, at the same time, the organic heat transfer media is circulating in the system pushed by the pump. And then the using-heat equipment takes heat from the media, which goes back to the boiler after heat exchange. So it is
