gas heating condensing water tube hot water boiler for sale

Structure and characteristics of Water Tube Boiler (double Longitudinal Tube Boiler)

The structure of the double vertical tube water tube boiler is mainly composed of upper and lower vertical tube, convection tube bundle, water wall tube, header box and down tube and other pressure-receiving components. The length of the lower drum is about half shorter than that of the upper drum. The empty space is provided with a furnace, a curved water pipe is arranged between the two drums, and a water wall tube is arranged around the furnace. The burning equipment adopts a gas/oil burner, and the tail flue has an economizer. The boiler evaporation is generally less than 20 tons / hour (t / h), the working pressure is less than 2.5 MPa (MPa). The high-temperature flue gas enters the rear convection flue from the right exit of the furnace, flows in an S shape along the two smoke-proof walls, flushes the convection tube bundle laterally, and then flows through the economizer from the left side of the furnace wall, and is discharged by the induced draft fan and the chimney.

How to use gas-fired boiler gas boiler includes a gas water boiler, gas heating condensing water tube hot water boiler for sale, gas steam boilers, gas hot water boiler which is also known as gas heating boilers and gas boilers bath, as the name suggests refers to the gas boiler fuel gas boiler, gas boiler and oil-fired boiler, electric boiler comparison economy, so most people have opted for a steam boiler equipment gas-fired boiler, heating, bath with. 1, boiler water, softening the first, but also to clean the water quality can not be an impurity. 2, gas boiler before the fire, you want to view the valve pipes, steam pipes, water gauge, pressure gauge and drain valve and so on, whether it is intact, whether the normal use. 3 and can not be conditioned to avoid rendering problems. If the gauge to reach the promised 80% working pressure, to avoid excessive pressure. 4, the water table in a glass tube, which should consolidate outer shield, but also to clean and tidy. How should the functioning of the water table at any time of the investigation, if any anomalies should be handled immediately. 5, when the gas boiler shutdown urgency, you want to cancel burning, then closed throttle, then open the door and release valve, the order can not be inverted. 6, when the pressure rises quickly, when and beyond promised to work pressure or boiler annex presents the phenomenon of failure, or a furnace, ducts appear deformed, when leaking air leakage, urgency should be shutdown immediately.

Fast Boiler Co., Ltd. is a really truly think about your clients practical solutions to business problems, this recommendation after this water-tube boilers put into use, the quality inspection departments, the nitrogen oxide emissions, soot and other indicators They are in line with national standards, but also very full of fuel combustion, high thermal efficiency, saves us a lot of fuel costs. This cooperation, I am very satisfied. --customer feedback

After the gas heating condensing water tube hot water boiler for sale 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.
