Because coal fuel is expensive and coal combustion can cause serious environmental pollution, it is necessary to transform the coal-fired boiler into gas-fired boiler. However, the reconstruction of coal-fired boiler is not a small project. Only pay close attention to every phase of the reconstruction process can avoid failure.
(1)Ensure normal and stable steam pressure, steam temperature and evaporation.
(2)Avoid coking and burner damage; Ensure the safety of the operation of the superheater; Reduce pollution of combustion.
(3)Make the operation achieve the highest economy.
If the pumps of a coal-fired boiler are not absorbing water, it could be due to several reasons. It's essential to diagnose the issue accurately for an effective solution. Here are some common causes:
Air Locks in the Pump or Suction Line: If there is trapped air within the pump or the suction line, it can prevent the pump from creating the necessary vacuum to draw water.
Low Water Level in the Feed Tank: If the water level in the feed tank is too low, the pump may not have enough water to dra...
Serious coal leakages in the fire grate of coal-fired boilers can be caused by several factors, each impacting the efficiency and safety of the boiler operation. Understanding and addressing these issues is crucial for maintaining optimal performance. Here are some common causes:
Wear and Tear: Over time, the fire grate components can wear down due to the constant exposure to high temperatures and the abrasive nature of coal. This wear can create gaps through which coal can fall.
Improper Grat...
The arrival of the heating season makes us realize that improving the efficiency of heating coal-fired boilers is crucial for comfortable indoor warmth. As a well-known heating equipment manufacturer, ZOZEN Boiler is committed to providing efficient and reliable coal-fired boiler solutions. The coal-fired chain grate boilers produced by ZOZEN can be divided into four series: SZL series double drum longitudinal chain grate boiler, DZL series single drum longitudinal chain grate boiler, DHL series...
Volatile matter in fuel, particularly in solid fuels like coal or biomass, plays a crucial role in the combustion process within boilers. Understanding the effect of volatile matter can help optimize the boiler operation for better efficiency and emissions. Here are the impacts of volatile matter on boiler combustion:
Ignition and Combustion Stability: High volatile matter content aids in the easy ignition of the fuel. As volatile components release and ignite rapidly when the fuel is heated, t...
What are the procedures and formalities for the retrofit of a coal-fired boiler?
The procedures and formalities for retrofitting a coal-fired boiler can vary depending on the specific regulations and requirements of the region or country. However, there are some general steps that are typically involved in the retrofit process:
1. Feasibility Study: The first step is to conduct a feasibility study to assess the technical and economic viability of the retrofit project. This invo...
The amount of coal burned by a large 660 MW boiler in one hour would depend on several factors such as the calorific value of the coal, the efficiency of the boiler, and the load at which the boiler is operating. However, as a rough estimate, a 660 MW boiler operating at full load and with an efficiency of around 38% would burn approximately 250 metric tons of coal per hour.
It's important to note that coal consumption can vary widely depending on various factors, such as the quality of...
