automatic switch-over gas fired hot water boiler

the fuel used in the horizontal boiler is natural gas which is transmitted to the boiler room through the gas pipe.The gas is convenient and less pollution. But in the using process, the probable leakage not only increase the fuel costs of enterprises, but also contain security risks, the following is the solving measures proposed by engineer:

1. the natural gas leakage treatment. For outdoor buried gas pipeline leakage, the Gas Co should be immediately informed to cut off the gas source, and the person in charge should report to the responsible departments. According to the natural gas leakage emergency treatment, indoor gas leakage: emergency shutdown, open the emergency air exhaust machine, cut off the total valve of boiler room, and report to the responsible departments, according to the natural gas leakage emergency treatment.

2. strictly regulate the industrial boiler gas design construction, uses the high quality boiler,burner, valves and other accessories, prevent gas leakage, strengthen management, regular inspection, must according to specification of the installation of gas leakage alarm device, and regular inspection.

3.no smoking and playing mobile phone in the industrial gas boiler room, no dumping any inflammable and sundries, real domestic demand the use of electric welding, gas welding operations, in strict accordance with the operation procedures, construction work by professional on-site monitoring, all those who enter the boiler room personnel are required to wear anti-static overalls.

4, when the industrial gas boiler gas leaks, gas concentration in the lower explosion limit before also need water spray extinguishing system protection. Using dilution water spray, the gas concentration decreased, can play the role of fire effect. Fire water and fire hydrant in good condition, especially in the cold winter, to prevent the pipeline freezing.

Comparison of natural gas and coal-fired boiler boiler: natural gas, including natural gas boiler water boiler, gas automatic switch-over fired hot water boiler, gas steam boiler, which is also called natural gas hot water boiler natural gas heating boilers and gas boilers bath, days as the name suggests refers to the gas-fired boiler fuel for the boiler of natural gas, natural gas boilers and oil-fired boiler, electric boiler compared to the most economical, most people have opted for natural gas as a steam boiler, heating, boiler equipment for bathing. Gas boiler comprising KS-Q water natural gas boiler, CLHS (CWNS) natural gas hot water boiler, LHS (WNS) natural gas and steam boiler, wherein the natural gas comprises a natural gas hot water boiler heating boilers and gas boilers bath, with the realization of the country "West-East" project, natural gas boiler gradually become the people's choice. "Special Equipment Safety Supervision Regulations" as defined in the boiler is the use of various fuels, electricity or other energy sources, the costumes, the liquid is heated to a certain parameter, and external heat output devices. Which is defined in a range equal to or greater than the volume of the pressure of the steam boiler 30L; outlet pressure is greater than or equal to 0.1MPa (gauge pressure), greater than or equal to the rated power and the pressure of the hot water boiler 0.1Mw;

Beijing New Energy Automobile Co., Ltd. is China's first to operate independently and gain new energy automobile production qualification of new energy auto companies, mainly engaged in new energy vehicles and key parts and components research and development, production, sales and service business segments, and the layout intelligent manufacturing, energy management, smart travel, Internet +, and other strategic emerging industries. In the new energy automobile manufacturing process, and a series of paint drying processes can not do without the help of automatic switch-over fired hot water boiler. Due to the company before the device has reached less than the growing production needs, the introduction of the 2017 mid-tail electric company producing heating pressure hot water boiler (CEDR0.7--95 / 70-Ⅱ).

Oil-fired boiler technical analysis when equal sulfur content greater body oil and coal, low-temperature corrosion of boiler fuel in general is much more serious than a coal-fired boiler, for two main reasons: 1 coal-fired boilers, especially pulverized coal, coal 90% of the ash content of the flue gas is taken away, fumes generated in the sulfuric acid vapor is adsorbed fly ash in the flue gas, sulfuric acid vapor in the flue gas is reduced; coal combustion, about half of the sulfur remaining in the ash . While combustion of oil, the sulfur content of the fuel is almost complete conversion of SO2, the fuel ash few, little fly ash in the flue gas, the flue gas adsorption capacity of the sulfuric acid vapor is weak. 2. higher hydrogen content in the fuel, about 11% to 12%, per ton of fuel combustion can produce about one ton of water vapor, when the fuel in the flue gas water vapor partial pressure higher than when coal, lignite but because with water and more exceptions detailed in Table 1 below. When these two reasons that the fuel, the concentration of sulfuric acid vapor in the flue gas is large, when the sulfuric acid vapor in the flue gas is not only a so-called thermodynamic point of water vapor partial pressure is low is formed, as shown in Table 1. When the flue gas in a small amount of sulfuric acid vapor, the flue gas dew point of significantly increased. Effect of sulfuric acid concentration on the corrosion rate is large, typically at a sulfuric acid concentration of 40% to 50%, the fastest etching. Due to use of fuel oil-fired boiler, the flue gas dew point is not only high, but the sulfuric acid concentration in the air preheater heating surface is also formed large, low-temperature corrosion is worse than boiler fuel fired boilers.

Condensing boiler - Wikipedia

2019-7-21·Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.
