Our other fast boiler in the boiler industry strength already heard, through cooperation proves that our choice is correct. This water-tube boilers installed very quickly, basically no delay our production process, bring benefits to the enterprise. --customer feedback

There are build on the control of emissions of nitrogen oxides boiler in order to achieve NOx emissions from combustion boilers of less than 30mg / m3, reached the world advanced level. Austrian far low nitrogen fuel gas boiler Staged Combustion Process of the invention into three regions in the furnace combustion techniques, primary combustion zone into the small portion of the fuel, the fuel required for the combustion air into the furnace in stages, the air volume of 80% left and right into the main combustion zone, the primary combustion zone of the upper (downstream of the flame) of the fuel injected into the secondary combustion and the formation of Carrying out a reducing atmosphere in the third zone into the combustion air required Further, complete burnout process. To create a discharge for the control of nitrogen oxides boiler fuel and air in order to achieve staged combustion gas boilers achieve emission limits is very basic configuration of environmental protection facilities, comprising an electrostatic precipitator or bag filter, gas boiler efficient desulfurization apparatus, a selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR) and the like denitration apparatus. All aspects of air pollution sources to install automatic monitoring facilities, steam boilers and networking with the environmental protection department, install a distributed control system (DCS system), real-time monitoring of gas boiler pollutant emissions. All-premixed combustion technology implementation of a number of Austrian far improved combustion technology after years of build have on the control of emissions of nitrogen oxides boiler fuel and air in order to achieve staged combustion. This technique can be gas boiler NOx emissions chain by 70% -60%. At present, to solve pollution problems of small and medium industrial gas boilers have four energy saving way. First, clean fuels covered by the remaining gas boilers, boiler premix combustion technology implementation of a number of improved combustion technology after years of Austrian far as natural gas boilers, biomass boilers and so on; Second, the rising water boiler technology.

How to deal with the failure of the gas burner boiler? How to deal with the failure of the gas burner boiler? Gas boiler with a combustion burner manner generally ejection liquid and gas, so that stable fuel injection, ignition a necessary condition. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass dzl 4 mw 1 0mpa biomass hot water boiler, biomass oil furnace. Boiler summarizes the four points of failure. Cause of these problems is different, not as ignition rods ignition, spark ignition rods single ignition, fuel injection increased strength unstable flicker noise large burners. The reason for these problems is different, the boiler needs to pay a lot of effort to collect them. First, the reasons many ignition misfire rod, such as clogging of the seam, moisture, leakage, ignition rods of different gap distances, skin damage, short circuit, all these reasons and due to improper operation caused by unscheduled maintenance. Troubleshooting not very difficult, can solve the cleaning, changeover, the ignition rod spacing problems.

Boiler "four" leakage phenomenon determines: whether the output of hot water, steam or thermal oil, and regardless of using coal, oil, gas, biomass or power boiler, has the following "four", respectively, of boiler waterwall tubes, superheater tubes, reheater tubes and economizer tubes. It covers all four pipes of the boiler heating surface, the internal pressure of the working fluid bear, may be external to bear the high temperature, harsh environment corrosion and wear, excessive reconcile between water and fire, where the energy is concentrated is passed .
