When the water level is high, the quality of steam will drop. This is because the water level will enter the steam-water separator, and the water will slide out with the steam.
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.
As a kind of equipment that needs to be used continuously for a long time, it is quite common for the boiler to malfunction due to operation errors or environmental quality problems. Today, Let’s discuss the causes, analysis and solutions of common faults of steam boilers.
Boiler furnace is a three-dimensional space surrounded by furnace walls, which is used for burning fuel. The function of the boiler furnace is to ensure that fuel is burned out as much as possible, and to cool the flue gas temperature at the outlet of the furnace to the temperature allowed by the safe operation of the convection heating surface.
Explosion doors mainly use their own weight or strength. When it is greater than or equal to the total pressure acting on the furnace at normal pressure, the explosion-proof door is closed. When the furnace pressure changes, the total pressure acting on the explosion-proof door exceeds the weight and strength of the explosion-proof door itself, the explosion-proof door will be flushed or broken, and a part of flue gas in the furnace will be released, thus achieving the purpose of pressure relief.
The main purpose of boiler acid washing is to remove iron oxide, copper scale, iron scale and other impurities in the evaporation heating surface of the boiler, and also to eliminate silicon dioxide and scale.
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.
