Generally, it is required that the water temperature shall be reduced to 80℃ to drain the water in the boiler. This is because if the water temperature is high, the temperature in the furnace is still very high, and the metal of the furnace wall and heating surface will still accumulate some heat. After the water is released, there is no working medium in the water wall to cool, which makes the wall temperature rise and the temperature rise is uneven, which is not conducive to the safety of the water wall.
The flue gas treatment of biomass boiler adopts the pretreatment and deep processing. The deep processing adopts the pulsed jet cloth filter, the waste gas treated by this system can meet the discharge standard stably. The flue gas enters the cyclone dust collector or flame arrestor through the dust removal pipeline.
It is necessary to confirm whether the boiler pressure is correspondingly higher when steam is not used and lower when steam is used. This is mainly due to the different water pressure and volume under different pressures.
The limited space refers to a space which is closed or partially closed, relatively isolated from the outside world, with narrow entrances and exits, staff can't work in it for a long time, natural ventilation is poor, and toxic, harmful, inflammable and explosive substances or oxygen content is easy to accumulate. To define a limited space, it is necessary to meet the following three conditions at the same time, which are indispensable: the volume is large enough for people to enter completely; Or restrict the entry and exit; It's not designed to stay for a long time.
During the operation of automatic boiler water softener, the role of salt is to backwash sodium ion resin to prevent the sodium ion resin from being poisoned by iron, so the salt will not be destroyed during operation. Pay close attention to the salt content in the salt tank. As long as the salt is continuous, there is no requirement for the salt content. However, for good control, the amount of salt is generally about two-thirds of the salt tank, and then filled with water.
Biogas boiler is a kind of boiler using biogas as fuel. It is suitable for new energy boilers in slaughter plants and breeding plants. Biogas boiler is a new type of energy-saving and environment-friendly boiler, which can not only save fuel cost, but also solve the environmental pollution problem.
Coking and dust accumulation on heating surface. Whether it is slagging and ash deposition on the water wall of the furnace or ash deposition on the superheater, convection tube bundle, economizer and preheater, the measured thermal resistance of flue gas will increase, and the deterioration of heat transfer will worsen the cooling effect of flue gas, resulting in an increase in the temperature of boiler waste gas.
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.
