ASME Approved Horizontal Packaged Gas Water boiler

Gas-fired steam boiler steam boiler gas to become the market trend is for countries to protect the environment, to control environmental deterioration and promote the steam boiler, gas steam boiler reconstruction is an arduous and urgent major project. Why the high price of coal to gas has changed, serious pollution of coal, especially in the past two years haze is particularly serious, mainly from coal to gas deal with environmental pollution, but the operating cost is much higher than gas. But the long-term development, economic development and should not expense of the environment, protecting the environment is everyone's responsibility. After gas steam boiler into a gas steam boilers, gas consumption is how much? Do not control coal, substantially in accordance with your boiler power to calculate, but one thing you need to think clearly, with the efficiency of gas-fired boiler efficiency gas boilers were quite different. So when you change 4 tons of coal boiler gas boiler, you can consider using a smaller gas-fired boiler. Coal to gas is a national policy not to install all right? Not installed, then it is possible, but now the country for gas-fired boilers is gradually ban, not to use, and if you do not choose coal to gas, then you need to select the coal to electricity, coal to heat pump etc., the gas must be slipping, these types of coal to the way you can compare each to see which is more suitable for their own gas steam boiler steam boiler gas into the benefits of what. Gas steam boiler includes a central water heater, new energy-saving, high efficiency stainless steel burner, electronic ignition pulse, a stainless steel coil heat exchanger, a strong discharge blower, intelligent control assembly elements, security devices and the like, the use of liquefied petroleum gas, natural gas, gas and other gaseous fuels, using the latest combustion technology design and manufacture of the heat exchanger, the thermal efficiency up to 95% water fast heating speed, high flow, with energy saving, easy to scale, automatic control without staff on duty, easy maintenance and so on. Economic and environmental performance far superior to the conventional type boiler modules may be stand-alone or in combination of line. Gas-fired steam boiler to save land resources, the same will not cause pollution like soot gas boiler. Gas boiler need to go through dust, slag process, complicated process, where the same water, gas boiler more environmentally friendly.

What is the state of a burning oil-gas boiler after it is put out? How to judge whether the burning oil and gas boiler is extinguished? Oil-gas boiler manufacturer-gas-fired Fangkuai boiler for you to introduce in detail: The indicator value of the negative pressure gauge in the furnace of oil and gas fired boiler suddenly increases, the furnace blackens, the flame can not be seen from the fire hole, the combustion sound in the furnace disappears, the flame monitor sends out the fire extinguishing signal. Air temperature, air pressure drops sharply, water level drops first and then rises, etc., all of which are extinguished. Due to the auxiliary engine accident caused by the quenching, such as induced fans, blower power interruption, there is also an accident signal; if the fuel supply interruption, the boiler fuel or gas pressure is reduced to zero.

After the gas hot asme approved horizontal packaged water boiler hot water boiler vaporization emergency 1. Vaporization handler circulating pump stops abnormally pump failure caused by: ① blower stops running immediately. ② immediately open the door, take measures to pressure the fire, lift the chute gate, cutting off the supply of coal grate. ③ In the case of boiler pressure not greater than 0.6MPa (600KPa), the exhaust valve to follow, only a sharp rise in pressure in the boiler deflated, used only relief exceeds 0.9MPa, and the exhaust process to be carried out slowly, prevention boiler due to loss of pressure and more violently again vaporized. ④ close the boiler water, water main gas valve. ⑤ open stop valve recirculation line, to ensure that the water supply pipe velocity convection heating surface (economizer) to prevent re-vaporization of the economizer. ⑥ The operation of the above operation, at the same time to pay the boiler to reduce the boiler water temperature and the furnace pressure. ⑦ After the boiler pressure is normal, i.e., opening the standby circulating pump, into the normal combustion. 2. Treatment failure or sudden loss of power boiler vaporization of power: ① immediately open the door, lift the coal chute slide gate to take pressure fire measures to reduce the oven temperature. ② Grate with the fastest speed in order in the shortest time to fire onto the slag tap. ③ the degree of treatment in the first case. Once a short time can not supply heating network system, antifreeze should take emergency measures. 3. Due to excessive heat boiler boiler vaporization process: ① the immediate closure of the drum, induced draft fan. ② immediately open the door, take measures to pressure the fire, lift the supply of coal chute slide gate, off of coal, while the grate into fast gear. ③ In the case confirmed the presence of water, the boiler can supply water to the boiler body, boiler out of the water while closing the main valve. ④ Open line stop valve recirculation pump to ensure water velocity convection heating surface of the pipe, to prevent the economizer again vaporized. ⑤ Open circulating pump with jog mode, jog each time less than 30 seconds, again less than one minute jog interval. Jog purpose is to reduce the boiler water temperature, while preventing a large amount of steam into the pipeline system. ⑥ back into place after the safety valve, circulating pump running, and then the normal burning stove. 4. Water boiler system run vaporization process due to water loss, loss of pressure caused by: ① immediately closed drum, induced draft fan. ② out of the water while closing the main valve and the boiler circulating pump. ③ take the same measures to cool the furnace tube described above. ④ Open stop valve recirculation line. ⑤ rely exhaust valve until the safety valve back into place. ⑥ until the boiler water temperature drops below 50 ℃, when the temperature of the furnace temperature less number 200 ℃, again within the boiler feed water, water course to be carried out slowly, to prevent harm to the boiler when the temperature is too large. ⑦ After processing leakage fault, the system time to the replenishment, and out of the water boiler always open the valve, and the circulating pump, and then normal combustion.

Fangkuai Boiler has carried out a large-scale welding revolution, eliminating traditional manual welding operations with low efficiency, low accuracy and poor stability, and converted it to the use of mechanical welding equipment with high efficiency, high accuracy and high stability for automatic operation . Realize welding automation of all important parts from the drum to the tube sheet. The submerged arc welding, argon arc welding, carbon dioxide welding and other welding details of the process have also made corresponding intelligent changes, workers' welding environment is cleaner, and the quality of boiler welds is more guaranteed.
