The main water quality indexes of medium and high pressure steam boiler water are hardness, dissolved oxygen, iron, copper, sodium and silicon dioxide.
When it is found that the boiler steam pressure can't rise, the first thing we should do is to check whether the water pump of the gas-fired steam boiler works and how much the pressure of the water pump of the gas-fired steam boiler can reach. When installing the water pump of the gas-fired steam boiler, a pressure gauge is installed on the water pump. This is because, if the gas-fired steam boiler does not add water, it can be detected whether it is caused by the water pump.
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 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.
Boiler steam pressure control refers to maintaining the steam pressure of boiler drum by adjusting the fuel control system. Its basic task is to adapt the heat provided by fuel combustion to the steam load of boiler drum. At the same time, it is necessary to ensure the safe and economic operation of boiler drum and meet the requirements of environmental protection.
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.
Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
