Two characteristics of environment-friendly thermal oil heater
1. Ultra-low nitrogen emission
Countries or regions, according to the actual environmental situation, have formulated the corresponding emission standards of boiler air pollutants, which have clear requirements for nitrogen oxides, sulfur dioxide, dust and flue gas blackness.
As a professional manufacturer of environment-friendly thermal oil heater, ZOZEN deeply studies low-nitrogen combustion technology, and its environment-frien...
The boiler economizer is a device installed at the lower part of the flue at the tail of the boiler to recover the waste heat of the exhaust gas. It absorbs the heat of the high-temperature flue gas to heat the boiler feed water, reduces the temperature of the exhaust gas of the boiler, saves energy and improves the thermal efficiency of the boiler. Therefore, when using boilers, it is very important to master the correct treatment method of boiler economizer tube burst.
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...
