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?

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...

What do the internal circulation and external circulation of circulating fluidized bed boiler mean?
Internal circulation and external circulation of fluidized bed boiler
The internal circul...
Commonly used dust removal equipment of SZL boiler includes multi-tube dust collector, wet scrapper and bag filter.
1. Multi-tube dust collector: XTD type vertical ceramic multi-tube dust collector has the advantages of wear-resistance, high temperature resistance, corrosion resistance, low cost, etc. Its collection efficiency is not less than 95%, resistance is not higher than 900Pa and mainly removed dust granularity is greater than 20um.
Design, manufacture and acceptance of multi-t...
The fuels of ZOZEN WNS gas/ oil fired boiler are mainly oil and gas. Oil and gas fuel are supplied to burner by piping conveying.
Oil fuel supply system mainly includes: oil storage tank, daily-used oil tank, oil filling pump and oil filling pipelines.
Oil storage tank: This is used to store oil for boiler combustion. Small capacity oil storage tank usually adopts buried layout and buried tank should be reliably fixed and be guaranteed not be floated by surface water. Oil tank that volume is m...
