The design and construction of boiler room is also a very important point in the safe use of boiler. The gas supply, combustion, inspection and other items of the boiler should also comply with the boiler room design code. As many users have consulted the question whether pressure boilers can be installed in the basement, ZOZEN Boiler here will give you a professional answer.
Can the pressure-bearing boiler be set in the basement? It is necessary to refer to the relevant design codes of...
Before degassing and dehydration, boiler parts must be checked, and detailed inspection items are as follows:
1.Burners work well, combustion is stable and combustion load change can be controlled freely.
2.Auxiliary such as FD fan, ID fan, oil system equipment and so on shall do cold test and run normally.
3.Lubricating oil shall be full filled in all bearing boxes and oil cups.
4.Inspection of safety accessories and protective equipment:
a) The needle valve or the stop valve in the pressu...
Boiler pressure is the main signal to indicate the combustion status and judge whether the combustion in the furnace is stable. Generally, it is divided into micro-positive pressure and negative pressure. What is the function of negative pressure boiler? What's the difference between a negative pressure boiler and a positive pressure boiler?
What is a negative pressure boiler?
The negative pressure boiler refers to the boiler equipment that keeps the furnace in a negative pressure stat...
A boiler is a kind of equipment that uses the heat released by fuel combustion to heat the working medium and generate steam at a certain pressure and temperature. It is composed of two parts: boiler and furnace. Meanwhile, in order to ensure the normal operation of the boiler, the necessary accessories, instruments and auxiliary equipment must be provided. Knowledge of boiler system is complex, so users often face many difficulties in purchasing. Here, ZOZEN Boiler will explain to you what is t...
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...
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) The furnace drying time depends on the shape, structure and humidity of the furnace. It takes 4 ~ 7 days for small low-pressure boilers and 10 ~ 15 days for heavy furnace walls.
(2) First, bake with wood, on the ash hopper of the room furnace and the grate of the chain furnace, use small fire for natural ventilation within 2 ~ 3 hours. When the temperature of combustion chamber rises, the ventilation capacity will be improved, and the flue damper can be turned down a little. It is best to k...
(1) The boiler and all auxiliary equipment are installed, and all tests such as ball passing test, hydrostatic test and air tightness test are qualified.
(2) All rotating devices, feed water pumps, condensate pumps, salt solution pumps, blowers and induced draft fans for coal conveying, combustion and ash removal are qualified for trial operation.
(3) The fuel and water supply are guaranteed, the steam, water and flue gas piping system are normal, and the connection unrelated to the boiler to ...
