A boiler is a kind of equipment that uses the heat released by fuel combustion to heat the working medium and generate steam at a certain pressure and temperature. It is composed of two parts: boiler and furnace. Meanwhile, in order to ensure the normal operation of the boiler, the necessary accessories, instruments and auxiliary equipment must be provided. Knowledge of boiler system is complex, so users often face many difficulties in purchasing. Here, ZOZEN Boiler will explain to you what is t...
(1) The furnace drying time depends on the shape, structure and humidity of the furnace. It takes 4 ~ 7 days for small low-pressure boilers and 10 ~ 15 days for heavy furnace walls.
(2) First, bake with wood, on the ash hopper of the room furnace and the grate of the chain furnace, use small fire for natural ventilation within 2 ~ 3 hours. When the temperature of combustion chamber rises, the ventilation capacity will be improved, and the flue damper can be turned down a little. It is best to k...
(1) The boiler and all auxiliary equipment are installed, and all tests such as ball passing test, hydrostatic test and air tightness test are qualified.
(2) All rotating devices, feed water pumps, condensate pumps, salt solution pumps, blowers and induced draft fans for coal conveying, combustion and ash removal are qualified for trial operation.
(3) The fuel and water supply are guaranteed, the steam, water and flue gas piping system are normal, and the connection unrelated to the boiler to ...
Before the boiler is put into operation, the furnace wall and arch must be baked and dried, which is called furnace drying. Furnace drying is to slowly dry the damp furnace wall and arch with warm fire to prevent ignition without furnace drying, causing cracking, deformation and serious damage.
Boiler safety accessories are indispensable parts of boiler operation, mainly refer to accessories such as pressure gauge, water level gauge, safety valve, steam-water valve, sewage valve, etc. These accessories are extremely important to the safe operation of boilers, especially pressure gauges, water level gauges and safety valves, which are the basic accessories for ensuring the safe operation of boilers. Therefore, they are often referred to as three safety accessories of industrial boilers.
There are many kinds of industrial boilers, for example, according to the boiler pressure, it can be divided into negative pressure boiler and micro positive pressure boiler.
As an effective tool in the era of environmental protection, gas-fired boilers are favored by all walks of life and widely used in food, paper, building materials, wine, chemical industry and other industries. With the increasing use of gas-fired boilers, there are more and more problems.
Low-pressure boilers operate at a lower pressure and reach lower temperatures than high-pressure steam boilers. Water in low-pressure boilers is not heated beyond 250ºF, and the steam pressure does not exceed 15 psi (pounds per square inch).
