Safety valve manual valve oil-fired boiler emission test is necessary to prevent security annex oil-fired boiler overpressure operation when the boiler pressure reaches the pressure relief valve jump start, jump start automatically relieve pressure. If the safety valve does not operate long-term, there is likely to stick to rust inside the valve structure, the valve can not be under pressure to adjust the automatic jump start, will cause the boiler overpressure operation, or even an explosion hazard boiler. In order to prevent the relief valve and valve seat stick, according to "Boiler Code" provides manual drain valve should be periodically tested. Oil-fired boiler Procedure: (1) in the boiler operation, when the state of the pressure pot 75% or more boilers operating pressure is reached, check valve use, to confirm the absence of abnormality, emissions test done manually; (2) valve lifting handle or the weight slowly, this time should jump start exhaust valve; (3) after 3-5 seconds, the weight or the handle down, the safety valve should be closed; (4) If the valve is not closed Yan, should be repeated by lifting the handle hammer until closed. If the valve is still closed tightly, the need for shutdown valve repair or replacement: stop the pump, the pump to stop, stop the fan off the main power, boiler exhaust valve opening, closing sub-cylinder inlet valves, valve disassembly, after repair or replacement, installation of safety valve, and then open the safety valve check if no abnormal, turn off the safety valve; (5) if jump start, a safety valve spool may be stuck foreign matter or embroidered dead, need for safety shutdown a valve for repair or replacement. Safety valve should be manually emission test points to note: (1) the pressure pot manual drain should be at least 75% of the state working pressure, prevent manual drain valve does not jump start at low pressure. (2) If there are two or more boiler safety valve, the discharge should be done in the first row of the high value of the low back valve. (3) for lifting and a manual valve handle should Qingtai light or weight, can not be used for lifting and Meng Jin. These are the emission test and safety valve manually precautions oil-fired boiler, we want to help.
Our emphasis on increasing green, local governments also 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 cheap dealer price 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 procedures and techniques fuel gas cheap dealer price steam boiler today gave us something about knowledge steam boiler installation of fuel gas bar. Fuel gas steam boiler installation there are many details that need attention, summed up the matter of installing the top ten fuel gas steam boiler Note: To ensure safety, customers must choose a fuel gas steam boiler installation qualification professional installation company to install. Fuel gas steam boilers should not be installed in a bedroom or bedroom with direct access from the room, not installed in the air is not smooth basement. Fuel gas steam boiler power supply using 220V / HZ alternating current, reliable ground wire must be connected to ensure safe use. Gas pipeline with the gas burner with gas for the pipe must be the link, the link can not be used flax, with raw materials must be used. After installing the gas pipeline, the gas valve is opened, a connection portion soap check for leaks, if any leakage off the seal valve repair or replacement, and then check the gas boiler, until no leakage so far. Gas steam boiler installation must be flat or rational design, as short as possible, less coarse, i.e. to shorten the pipe, reducing the curve, diameter to be rough. In addition the return path should be in charge of the gas boiler outlet back to the same diameter. Natural circulation Sheung gradient slope and the return pipe main conduit are 3-5%, waves appeared not to prevent blocking gas pipes, exhaust system piping system should be placed at the top, and the valve can not be installed. Minimum system blowdown valve installed at the bottom of the tank fill pipe should be above the highest point of water, the atmosphere port through the automatic vent valve can not be replaced, the valve can not be mounted, must not be obstructed. Gas-fired steam boiler system piping length, bend over, no gradient, Heating ineffective should be installed circulating pump, water pump to be installed on water pipes, select pumps according to the size of the heating area.
1, natural gas boiler degree of automation is very high, generally need only a simple user interface control, to complete the startup, shutdown and adjustable parameters, labor cost is very low.
2, flue gas condensation recovery boiler is provided with a tail, by the secondary recovery of the high temperature flue gas, so that the thermal efficiency is further enhanced when the gas boiler flue gas temperature is reduced to below 80 ℃, its efficiency can be increased to 108 %the above.
3, the internal gas boiler larger heat transfer area and wings tubes finned tubes, light pipes in general, the heat transfer area can be increased 5-fold compared to the overall area of the boiler is directly reduced about 40%. For less demanding to build a boiler room, boiler room can save capital costs.
4, due to the natural gas boiler using clean energy sources, will not produce the combustion process in the furnace soot and dust, the degree of smoke pollution emissions is also low, truly clean and green, can significantly improve the use of units on-site environment, regional environmental requirements to be high, and has a clear advantage.
5, the choice of materials, natural gas boilers do a great degree of change, anti-corrosion treatment, pipe insulation, packaging materials ...... These measures have made the boiler has stronger corrosion resistance, life will naturally run longer than other types of boilers.
