Existent problems of gas boiler heating and application of energy saving techniques to boiler plants

Based on the survey of gas boiler heating， points out the problems existing in “gas for coal”. Analyses the reasons and puts forward six energy saving techniques， including weather compensator system， condensing technology， boiler centralizedcontrol system， regulation of frequency conversion fan burner system， hydraulic balance system and room thermostats. Applying all the techniques above to several boiler plants achieves good economic and social benefits.
