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.
In recent years, the state has stepped up efforts of prohibiting the traditional coal-fired boilers. Major enterprises keep up with the times and purchase various environmental protection boilers. Gas-fired boiler is currently the most popular environmental protection boiler. However, due to geographical limitations in some areas, natural gas is difficult to obtain, or the cost is too high, some enterprises will choose biomass 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.
First of all, the boiler water and steam are two concepts. It is the unit of measurement for boiling water boiler. What is a boiled water boiler? It belongs to the category of normal pressure hot water boiler, which heats the water temperature to boiling state. To ensure safety in use, the top of the boiler is provided with a nozzle communicated with the atmosphere. If steam is discharged automatically, the boiler will always work under normal pressure, so its attribute is normal pressure hot water boiler.
Fuel injection nozzle of combustion oil pump of gas boiler does not inject fuel. Possible causes include blockage and leakage of oil supply pipeline. The solution is to clean, repair or replace;
The manufacturers with different scales will have different price policy on the natural gas boilers. The prices of natural gas steam boilers in some large boiler enterprises are higher, while those in some small enterprises are lower. The difference lies in the raw materials, the production process, the quality of employees, and the service management of the company.
The reduction of nitrogen oxides in gas-fired boilers is mainly achieved by burners and increasing the furnace size of boilers. In order to help enterprises save costs and reduce nitrogen oxides in gas-fired boilers, low-nitrogen transformation can be realized by configuring appropriate low-nitrogen burners and staged combustion technology plus the flue gas internal circulation technology, and the emission can be controlled to be less than 30 mg/m3.
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.
