gas hot water atmospheric pressure boiler for sale

Work and family considerations hot water atmospheric pressure boiler for sale shutdown boiler inspection carried out maintenance before restarting operation, the need for a series of maintenance work, combined with the user experience and learning references, be aware of the following specific boiler maintenance work and family considerations. 1. Preparation (1) before the boiler before the boiler equipment maintenance inspection, as in normal shutdown program is stopped, slow cooling, water circulation and ventilation through the furnace, and gradually lowering the temperature of the boiler furnace. When the temperature dropped below 80 ℃, the door opening open various checks on the boiler. Prevent steam, hot water or cigarette burns when opening the door opening. (2) Steam test boiler feed water, should be separated from the sewer line with the respective other operation of the boiler. Blind for a separator plate should be sufficiently strong to avoid high pressure medium in the broken drum is operated. This clearly indicated the blocking position. Combustion chamber and the flue (3) Check the boiler should be separated from other operation of the boiler. Flue and ventilation doors must be closed tight after separating. 2, preparation of the pressure vessel (1) before the container inspection prior to examination, to be completely cut off the connection tube between the container and the gas pressure or other equipment, particularly equipment using flammable or toxic media. Not only must the valve is closed, and must be sealed with blind plates, so that the valve leaks, resulting in leakage of flammable or toxic gases into the vessel, fire, explosion or poisoning. (2) all media in the container to be discharged. Containers containing flammable, toxic or suffocating medium should be cleaned, replaced or sterilized, by sampling and analysis. A power supply associated with the container, such as a container with a stirrer, reversing mechanism, etc., must be cut off, and a clear flag indicating not allowed to connect. 3, a boiler maintenance considerations are (1) Note ventilation and monitored prior to entering the drum, the container, the drum must be opened, all in the hole hand hole in the container and the collection tank, the air convection period and adequate ventilation. When entering the drum and the container inspection, one must monitor the external device. Before entering the combustion chamber or flue must also be ventilated. (2) Note that the detection of electrical safety in wet flue drum and when the lighting voltage should not exceed 24 volts, with electric lighting. In dry flue, using appropriate security measures, it may be no more than 36 volts lighting voltage. When entering the test vessel, should be used no more than a low-pressure proof lamp voltage 12V or 24V. When the supply voltage detection equipment and maintenance tools than 36V, good insulation must be reliable grounding cord. Boilers and containers should not be used flame. (3) removably connecting member pressing the forbidden band in the inspection of boilers and pressure vessels, pressure if the fastener member needs to unload or screwing, must fully release the pressure, before it can be. Bolts or other fasteners can not be tightened or unloaded at the boiler pressure, in order to prevent accidents. (4) prohibits self-test instead of the hydraulic pressure to the boiler pressure vessel test pressure test generally use water as the pressure medium, there is no gas as a pressure medium, otherwise it is very dangerous. For structural reasons the like, water can not be used as a pressure medium test individual containers, when instead of hydraulic pressure in accordance with design requirements, should be thoroughly checked before the test, check the strength and reliability of the measures taken. Prior to implementation should conscientiously implement the design in accordance with the provisions of, and prior consent of the security sector.

Comments about the hot water hot water atmospheric pressure boiler for sale structural principle: electric hot water boiler containing hot water boilers, hot water boiler fuel, gas hot water boilers and coal-fired hot water boilers, hot water boilers hot water boiler that is working is to use fuel burning release of thermal energy can heat or otherwise for heating water is heated to a temperature of additional tools. Natural circulation boiler water, inlet and outlet are on top of the receiving drum, the water is divided into water guide pipe and lowered into the front side lower header pipe, through the waterwall tubes into the heating rise. The front drum, and proceeds under reducing water impermeable liner is provided at the boundary, only the lower half of the impermeable plate spaced transverse to the drum.

After installation and commissioning fast Boiler professional and technical personnel, two hot water hot water atmospheric pressure boiler for sales to provide our bodies quickly into the orbit of the normal operation. Meanwhile, the design of energy-saving equipment also effectively improve the thermal efficiency of the boiler, saved us a huge amount of fuel costs. --customer feedback

After the gas hot water hot water atmospheric pressure 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.
