A firetube boiler can react very quickly to load changes due to the fact that it has a large volume of stored energy in the form of hot water and steam.
Gas-fired boiler uses natural gas, biogas, coke oven gas, etc. as fuel, it has high combustion efficiency, and its emissions are commonly used energy equipment in food, chemical, building materials, medicine and other industries. The rated output of gas-fired boiler is generally used to describe the heating capacity of boiler. Here, ZOZEN Boiler will take you to learn how to choose the rated output of gas-fired boiler.
Rated output of gas-fired boiler
The rated output of the gas boiler refers ...
The gas-fired boiler is applied in all walks of life. In order to ensure its safety in use, it is necessary to design the boiler room according to the specifications. In boiler installation, it is necessary to comply with the standard requirements of site, space and protection. What is the installation height of gas-fired boiler?
Regarding the installation height of gas-fired boilers and the requirements of various details, we mainly refer to the Code for Design of Boiler Room and the C...
Boiler output refers to the maximum continuous output of the boiler under rated parameters (pressure, temperature) and certain efficiency. For steam boilers, it is called rated evaporation, and the unit is tons/hour; For hot water boilers, it is called rated heat production, and the unit is MW.
What are the main factors affecting the output of gas-fired boilers? According to the analysis of ZOZEN Boiler engineers, there are many reasons for the insufficient output of gas-fired boilers,
...
Different users have different requirements for boiler configuration. For example, some users need NOx emission less than 30mg/Nm3, and some users only need it less than 80mg/Nm3. The better auxiliary equipment configuration is used, the price of boiler will naturally rise.
Different users have different requirements for the configuration of the whole boiler system, and the brand and quantity of auxiliary machines also affect the price. The better the brand, the more expensive the price. For ex...
The first technical problem is the reconstruction of boiler body:
The coal-fired boiler is mainly grate firing boiler. For small water-tube hot-water boilers, it may lead to the water temperature at the outlet of the riser exceeding the limit or overheating boiling or even vaporization. For shell-and-tube boilers, the rising flue gas temperature at the furnace outlet will make the working conditions of the tube plate worse, thus causing cracks and leakage of the tube plate.
Different steam pressures correspond to different steam temperatures.
1. The steam temperature of low-pressure boiler is mostly saturation temperature or not higher than 400℃.
2. The outlet pressure of medium-pressure boiler is 3.8 ~ 5.4 MPa, and the commonly used steam temperature is 450℃.
3. The outlet pressure of sub-high pressure boiler is 5.4 ~ 9.8 MPa, and the common steam temperature is 540℃.
Fuel injection nozzle of combustion oil pump of gas boiler does not inject fuel. Possible causes include blockage and leakage of oil supply pipeline. The solution is to clean, repair or replace;
