98 heat efficiency electrical boiler

98 heat efficiency electrical boiler

First, when the need for boiler pressure test? 1, the newly installed boiler when put into operation. 2, more than a year boiler outage and resume operation. 3, boiler, pressure member after significant repair or replacement, such as the number of water wall tubes in the replacement number of more than 50%, superheater, reheater, economizer other group member replacement, a significant repairs performed drum Time. 4, severe boiler overpressure 1.25 times the working pressure up to and above. 5, when a large heating surface area of ​​the boiler water after severe deformation. 6, according to operation, safety and reliability of equipment operation when there is doubt. Second, the method of pressure testing a boiler water pressure test should be carried out when the ambient temperature is higher than 5 ℃, antifreeze measures must be less than 5 ℃. 2, the water pressure test should be maintained above the ambient dew point temperature, to prevent surface condensation boilers, water seepage and the like will not occur closely confusion, difficulty increases inspection; but it should not cause high temperature to prevent vaporization (so difficult to find the leak) and excessive temperature stress, usually 20 ℃ ~ 70 ℃. 3, the water is full, pressure is gradually increased to 0.4MPa, namely a tight check, if necessary, be tightened once the flange, and hand Manhole cover bolt hole. 4, water pressure test, pressure should slow down, when the pressure rises to the pressure of work, should be suspended boost, check for leaks or anomalies, and then boosted to the test pressure for 20 minutes, if the pressure It did not decline, that is, down to the working pressure checked. 5, find any leaks should cook the recording, in order to reduce the time to repair the atmospheric pressure.

Learn steam boilers and boiler selection computing applications: boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, the boiler after the conversion, externally output having some heat steam, hot water or organic heat carrier. The original meaning refers to the pot on the fire heated containers that hold water heater which places combustion of the fuel, boiler and furnace boiler consists of two parts.

Fast boiler is in Anyang City, scientific and technological innovation high bar business, we already heard. After this cooperation really deserved reputation, since the boiler to provide us with a self-running, never malfunction or accident. It comes with a complete remote monitoring service, eliminating our worries. --customer feedback

The cross section of boiler hearth is generally square or rectangular. Fuel burns in the furnace to form flame and high-temperature flue gas, so the furnace wall around the furnace is composed of high-temperature resistant material and thermal insulation material. Water-cooled wall tubes are often installed on the inner surface of the furnace wall, which not only protects the furnace wall from burnout, but also absorbs a large amount of radiation heat from flame and high temperature flue gas.
