Various components of the electric steam electric high pressure steam boiler is composed of different materials. 1, in order to prevent the occurrence of electrochemical corrosion, cathodic protection measures must be taken. 2, for the treatment of sewage, electric boiler blowdown bottom of the boiler flue gas condensation can be prevented. Since the flue gas is flue gas condensation (diesel or natural gas) and the flue gas temperature in the aqueous too low, water generated. A portion of the moisture is discharged from the chimney, the chimney wall is absorbed, the rest is deposited on the bottom of the chimney.
February 13, 2019, a food processing plant in Heilongjiang province, after the Spring Festival to resume production process, electric high pressure steam boiler explosion accident occurred, killing two people were killed, to the masses lives and property of people come at a cost, resulting in adverse social impact .

As of now, law enforcement officers deployed 116 times, check unit 52, checks the boiler 64 for five in the boiler there are security risks of Special Equipment Safety Supervision issued a letter of instruction, ordered to stop using, be put into use after the rectification qualified.
4 tons steam electric high pressure steam boiler fast boiler's Henan small series with you briefly quick 4 tons a steam boiler. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of a steam boiler. He said first boiler say "pot." This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. A chain grate combustion section and drive means, coupled with the combustion chamber pan rack on the frame configuration composed of the grate. Four weeks envelope refractories. . From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blast into the lower part of the combustion chamber is a place that boiler greater resistance, need to force the blast. Cinder burn out, the rear portion of the grate by the "beak iron" discharged from the slag out of the furnace feeding machine. The boiler flue gas from the rear, by the front drum smoke tube a return line, the return from the two rear return smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. Not only is the induced draft fan exhaust fumes, the negative pressure of the boiler operation is required. Steam boiler pressure vessel, the safety device is necessary. Boiler necessary water level gauge, pressure gauge, safety valve, thermometer, and under the pressure of the electric pump can pay, and the vapor pump when power is off can also be used.
Electric steam electric high pressure steam boiler before the preparatory work needs to be done to prepare the working electrode is a kind of steam boiler power for energy conversion from electric energy into thermal energy, the hot water or organic heat medium (HTF) is heated to a certain portion of the boiler through the heat exchanger parameters (temperature, pressure) and externally output has a nominal thermal Machinery working fluid. The use according to electric boiler can be divided into: KS-D electric water boilers, CLDR (CWDR) electric water boiler (including an electrical heating bath boilers and electric boilers), LDR (WDR) electric steam boiler. Steam boiler is the production of specified parameters and quality of steam boilers. Quasi-electric boiler steam preparation work needs to be done to prepare one thousand work (1), the operator must understand the working principle of the boiler, location, performance and working methods of the various accessories. (2), check the oil combustion, and each nozzle connection, power supply and the burner, the pump, the boiler installation accessory. (3), a clear main steam valve open, after closing the normal close it. (4), water level gauge inspection, confirmation flexible water level, normal position. (5), the pressure regulator is properly tuned, regulate combustion damper.
