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, promotional pellet horizontal 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.
Beijing SL Pharmaceutical Co., Ltd. as China's key high-tech enterprises, has great influence in the pharmaceutical industry. In early 2017, two-Heron relevant person in charge to get in touch fast boiler, double-Heron Pharmaceutical according to demand, our company to provide a 1-ton split steam condensing promotional pellet horizontal steam boiler, and is responsible for subsequent transportation, installation and commissioning work .
10 tons of horizontal gas hot water boiler safety features Henan party nearly 10 tons of gas hot water boiler can be divided according to the type of gas hot water boiler WNS and SZS gas hot water boiler, meaning both what is it? WNS means is a horizontal-type combustion chamber burner, meaning that double drum SZS vertical type burning furnace chamber, although the two different processes of different structures, but the fuel and the safety device are the same. This chapter focuses to introduce safety protection system of the two kinds of boiler: 1, interlock protection system ① As the two kinds of dual-use oil and gas boilers are in this together computing, once the fuel or air pressure below the minimum set when the standard, it will automatically cut off the fuel supply ② cold water delivery device event of a failure, will automatically cut off the fuel supply ③ water temperature is higher than the highest temperature setting, will automatically cut off the fuel supply 2, the most dangerous place is the ignition system boiler system , because many of these conditions could not be controlled once the ignition, so the first firing of the furnace should be purged to avoid residual combustible gas combustion furnace, after the purge, ignite pilot fuel (oil or gas) flame monitor reflects the flame existence, and it continues to burn about 10s. After 10s, the main fuel valve (oil or gas) driven i.e., ignite the main burner. If the normal main burner combustion, the ignition system is automatically shut down. 3, turn off the boiler system we know if it is to continue to provide fuel to the furnace in the flame will cause serious consequences of an explosion, this one so fast Henan party made a special detection device, or burn when the ignition fails halfway flameout, general in the 5S (ignition) or the 10s (runtime) off oil, gas solenoid valve, with sound and light alarm signal. 4, via the feedwater system to a steam cycle water injection drum seat, gall direct flame furnace, the flame furnace heat absorption, the heat absorption of smoke tube furnace high temperature flue gas discharged water, boiler water becomes progressively heated steam, by after separation water separation means leads from the main steam valve. Henan party fast as a professional gas boiler manufacturer, has 70 years of design and manufacturing experience, customers throughout the country, the most recent of several large cooperative enterprises and 10 tons of gas hot water boiler, Zhengzhou University, Zhengzhou Yutong Bus with 10 tons of gas hot water boiler, Gongyi aluminum plant with 10 tons of gas promotional pellet horizontal steam boiler, your trust is fast Henan party's power in the service of idealism Henan party fast, quality-oriented principle never live up to your commitment to your trust!
How to choose the heat exchanger is a promotional pellet horizontal steam boiler Shandong? To steam boiler insulation damaged condition for viewing prior to use, view of the burner, to see whether the normal operation, but also to see to make sure the valve open position is correct, to view the attachment security equipment, instrumentation equipment and devices automatic control equipment must meet the requirements. Point blast furnace steam boiler admit items are: open oil circulation pump before and after the valve, the valve open oil heating process, mediation high tank level in a reasonable position, admitted that the gas pressure before the gas burner must be burned in power scale, power supply normal.
