After completion of the gas factory central heating boiler cleaning, be sure to use hot air to dry them, but not both for heating the furnace walls and other accessories, this is likely to have adverse consequences. Right way is to place an electric heater in the bottom of the gas boiler, heated.
Our emphasis on increasing green, local governments also factory central heating boiler operation produces nitrogen oxides and smoke emission requirements become more stringent. Fast boiler followed by the national trend of development, deepening of cleaning boiler product design and development. Lulu as a representative of business development of the national beverage, and hope to find a set of boiler energy conservation and clean in one, for drink production process of fermentation, sterilization, drying, curing and other processes. After many visits and market research, in October 2017 and entered into boiler fast boiler purchase contracts, purchase two 10 tons of steam and a whole 20 tons of steam condensing steam boiler. The two sides this cooperation is the other quality fast condensing gas boiler highly recognized, has proved a powerful strength fast boiler in the boiler production and service of gas condensate from the side.
The transformation of low nitrogen factory central heating boiler should be noted that what matters for retrofitting low nitrogen boiler should be noted that what? Of nitrogen oxide emissions is large, complex sources, environmental problems caused by acid deposition, fine particles, ozone, nitrogen oxides and analysis of contamination status must be further strengthened. If you do not take further measures to reduce emissions, with the United States and the United States to speed up economic development, population growth and urbanization, nitrogen oxide emissions will continue to grow in China in the future. Based on current trends, by 2030, emissions will reach 35.4x106 tonnes, will inevitably cause serious environmental impacts. Therefore, we must effectively enhance the emission control of nitrogen oxides. From this we can see that low nitrogen boiler is imperative! A check device to check for low NOX combustion gas before commissioning is in place, the gas pipeline flow is clean, whether the valve is open. There is a burner pipe leaks, reasonable pipeline installation. Discharging vent pipe valve from the foregoing, to ensure that no mixing of the air duct, and the exhaust pipe should be connected to the outdoor. Second, stable combustion and combustion of homeostasis Remember, combustion adjustment is the basis for all of the low nitrogen burner adjustment, as long as guaranteed under any changes in operating conditions of combustion stability and combustion of dynamic equilibrium, to burn steam temperature influence is even greater. Since the steam temperature is a sign flue gas heat value balance between the steam and heat absorption, this can be maintained as long as the dynamic balance, steam temperature can be kept stable. Third, the level of flame boiler boiler central flame center is also an important factor in high impact low-temperature steam. In the high temperature steam operation, the amount of coal combustor exhaust can be reduced, the amount of the lower stage burner of coal may be increased, and vice versa. Running low nitrogen burners, it should also be noted effect of different combinations of temperature steam mill. Steam at a low temperature exhaust composition regulating a large margin, the combination of the high temperature exhaust temperature adjusting stage so small margin overheat. It should be strengthened and soot blowing air distribution according to the situation.
2, tightness test
Indoor gas boiler pipes tightness test should be consistent with the following requirements:
① low pressure gas pipe test pressure boiler for planning a pressure not less than 5kPa, under the experimental pressure regulator least 30min, and view all the joint with the blowing agent, no leakage, no pressure gauge pressure drop qualified equipment. When the experimental system stainless steel corrugated hose, plastic composite pipe, oil hose, when the plastic cover brass, IH pressure not less than the experiment, in addition to sealing the respective view point, the end surface of the cladding layer should also whether there is leakage phenomenon View.
② medium pressure gas pipelines boiler pressure test planning more pressure and not less than 0.1Mpa. Under the experimental pressure regulator less than 2h, and view all joints with a blowing agent, no leakage, no pressure drop pressure measurement device qualified.
