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...
Flue Gas Recirculation (FGR) is one of the most effective techniques employed in modern boiler systems to achieve low emissions of nitrogen oxides (NOx), a group of pollutants responsible for smog formation and acid rain. To truly appreciate the value of FGR and its widespread adoption in boiler technology, it's essential to delve into the underlying principles and its benefits.
1. Nitrogen Oxides (NOx) in Boiler Combustion:
When fuel is burned in boilers, several by-products are formed. Among...
When it comes to gas boiler efficiency testing, it’s essential to understand the set of standards that govern this process. These standards not only help measure the performance of the boiler but also ensure that it meets specific safety and environmental regulations. Typically, in various countries, this could be a national standard or an internationally recognized one like the ISO (International Organization for Standardization) standards. For instance, in the United States, the American...
To understand the air flow requirements of a 10-ton gas boiler, it's essential to comprehend the mechanics behind boiler operation. A boiler's efficiency and safety are largely contingent upon the proper mixture of fuel and air, both in terms of volume and velocity.
Fundamentals of Boiler Air Flow:Combustion Process: For a gas boiler to operate efficiently, the fuel (in this case, gas) must burn completely. A proper mix of fuel and air is essential for complete combustion. Insufficient air flow...
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...
The regulation for the exhaust temperature of a gas boiler chimney outlet may vary depending on the specific jurisdiction and the type of gas boiler.
In general, the exhaust temperature of a gas boiler chimney outlet should be below the flue gas dew point to prevent condensation and corrosion in the chimney. The dew point temperature can vary depending on the composition of the flue gas, which can be affected by factors such as the type of fuel being burned and the efficiency of the boiler.
So...
Gas-fired boiler uses natural gas as fuel, and the heat generated by combustion heats the medium, and then transports the medium to the heating equipment using thermal technology. The gas-fired boiler system consists of many components, with slight differences. Some users will find that flue gas recirculation pipes will be added to the gas-fired boilers in use. In this regard, we are analyzing the function and principle of flue gas recirculation pipe of gas boiler for everyone.
Function...
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.
