Industrial boiler is a kind of energy equipment widely used in production. The energy equipment is a boiler system composed of boiler body, combustion engine, fan, motor, etc. If you want to operate the boiler system correctly, it involves all aspects.
When purchasing the gas-fired boiler, the enterprise will generally require to visit the boiler factory at the later period of boiler procurement. Via visiting the boiler factory, the enterprise can have a comprehensive understanding of the operation process, production scale, product quality details, corporate management level, factory shipment and other information of the boiler factory, and can further understand the service quality of the boiler manufacturer.
It depends on the system of the gas boiler, the boiler water temperature at 60-90, 90-150 and 70-130 can achieve better energy-saving effect.
Energy-saving devices such as condensers are added to ZOZEN gas-fired hot water boiler. The waste heat is used to increase the water temperature of the gas-fired boiler. The rated inlet temperature is 70℃, and the exhaust gas temperature is reduced, so that the thermal efficiency of the boiler is increased to over 98%.
Combustion system: The combustion system of coal-fired thermal oil heater includes base, grate, furnace, etc. The combustion system of oil/gas heat-conducting oil boiler includes furnace, burner, ignition device, etc.
Oil circulation system: circulating oil pump, oil injection pump, storage tank, expansion tank, etc.
Control system: complete with boiler control box.
Air-smoke system: refers to the system composed of flue gas and air generated by combustion, mainly including induced draft fans...
1. Water leakage on the inner wall: Water leakage on the inner wall can be divided into three types: boiler leakage, water wall leakage and downcomer leakage. If the leakage holes of boiler barrel and water wall are relatively small, it is ok to use steel with the same steel grade for patching and flaw detection. If the downcomer is leaking, it needs to be replaced.
2. The hand hole leaks: you can re-install it from another angle to see if the hand hole cover is deformed. If it is deformed, you...
1. The defective parts in the last inspection.
2. Whether there are cracks and corrosion on the inner and outer surfaces of boiler pressure components, especially on openings, welds, edges and so on.
3. Whether the pipe wall is worn or corroded.
4. Whether there is any crack, fracture or corrosion at the brace of the boiler and the joint with the pulled element.
5. Whether the expansion port is tight, and whether there is annular crack in the expanded part of the pipe end.
6. Whether the ri...
Safety accessories of the thermal oil heater include safety valves and bursting discs, stop valves, pressure gauges, etc.
The basic configuration of low nitrogen thermal oil heater system includes the following main parts:
1. Combustion system: including furnace, burner, ignition device, etc.
2. Oil circulation system: circulating oil pump, oil injection pump, storage tank, expansion tank, etc.
3. Control system: complete with boiler control box.
4. Air-smoke system: refers to the s...
Raw water: refers to water that has not been disinfected and filtered, such as river water, stream water, well water, reservoir water, etc.
Feed water: refers to the chemical water delivered from deaerator to boiler by feed pump.
Make-up water: Make-up water for boiler is to make up the lost part or externally supplied part after completing a steam-water cycle, so that the boiler can always operate at a safe water level.
Recycling condensing water: When the heat energy of steam or hot water i...
