Before coking and boiling, check boiler parts detailedly. Inspection items are as follows:
1. Before coking and boiling, chain grate should be cold test run again and continuous running time shall not be less than 24 hours.
2. Ignition door can be opened flexibly, coal gate can be lift and dropped conveniently, coal gate left and right side is of the same distance to grate, and ensure the material layer thickness on both sides of the furnace is equal. If distance is not equal, it can be adjust...
1. After boiler body, economizer, air pre-heater, dust collector, etc are in place and installed, connect FD fan, ID fan, etc according to drawing and then connect corresponding flue gas duct. After fan in place, alignment between foundation and equipment base should be conducted with parallels. Fan position alignment should center on a shaft, central elevation deviation and vertical and lateral central line positional deviation should be 10mm or less and fan spindle should be in level state. Th...
1. Burner should be installed in accordance with requirements of burner installation and operation manual.
2. Burner should be installed in the center of the reserved front wall hole, the embeded length should comply with the design requirements and the fixation should be reliable.
3. Burner center deviation shall not be more than +2mm and air adjustment actuator should be flexible.
4. Burner and boiler body junction surface should be sealed reliably, the position that needed to be sealed bet...
The design and construction of gas boiler room is also a very important point in boiler safety. How to install the gas boiler should also conform to the boiler room design specification, and it is necessary to comply with the site, space, protection and other aspects.
How to install the gas boiler?
How to install the gas boiler is mainly based on the Boiler Room Design Code and Boiler Safety Technical Inspection Code. In addition, the Urban Gas Design Code and the Fire Protection Code ...
As a clean fuel, natural gas has much lower sulfur content and nitrogen content than coal, and there is no ash in the fuel, and the flue gas produced after combustion is almost smoke-free. Therefore, a nationwide upsurge of coal to gas has been set off.
However, there are some problems in the process of gas boiler operation, among which the hardness, harm and treatment of gas boiler flue gas condensate are prominent.
When the boiler flue gas temperature is lower than the dew po...
The main working principle of industry is a kind of heating equipment which uses the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the medium in the container, so that the medium can reach the required temperature, and then it can be transported to the heating process for heat exchange. According to different media, boilers can be divided into many types.
Types of boiler heating medium
1. Steam, steam boiler and superheated steam b...
Precautions for long-term work in the boiler room
1. Standard setting. Nowadays, most boilers are operated by PLC control system. Therefore, when setting, the boiler should be operated according to the factory instructions, so that the boiler can work within the required range.
2. Water level and water quality. Check whether the boiler water supply facilities are normal and whether the boiler water level meets the requirements. In addition, check whether the water quality is up to standard and...
The circulating pressure of a thermal oil boiler is generated by the driving of the circulating oil pump to the thermal oil circulation. Generally, the working pressure of the thermal oil pump is 4 ~ 8kg / cm2. Actually, the pressure of the thermal oil pump differs from different working conditions.
What are the factors that affect the maximum pressure of thermal oil heater?
1. Pressure of circulating hot oil pump
The pressure of liqu...
