Furnace drying, often also called "oven drying" or "boiler drying-out", is an essential step when commissioning a new circulating fluidized bed (CFB) boiler or after any maintenance that might have introduced moisture into the system. The purpose is to remove moisture, ensure the refractory and insulation materials are dry, and prepare the system for safe ignition and operation.
Here are the general steps involved in furnace drying for a circulating fluidized bed boiler:
Inspection: Be...
Typically, a steam boiler should receive servicing at least once per year. Any kind of safety failure with a boiler can have serious consequences, and so a yearly inspection will help to spot any safety issues that need to be addressed. Servicing your boiler on a regular basis can also help you to save money on repairs. If you spot a problem during routine maintenance, there's a good chance you'll be able to fix it at a much cheaper cost than if the problem goes unnoticed and becomes a larger and more serious issue.
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...
There are several ways to estimate the thermal efficiency of gas-fired boilers:
1. Direct method: This method involves measuring the amount of fuel consumed and the amount of heat produced by the boiler. By comparing these two values, it is possible to calculate the thermal efficiency of the boiler.
2. Indirect method: The indirect method involves measuring various parameters such as flue gas temperature, ambient air temperature, and fuel consumption, and then calculating the t...
Industrial boilers are an essential part of many manufacturing processes, providing the steam and hot water needed to power machinery and heat buildings. However, they can also be a significant source of energy consumption and greenhouse gas emissions, making it essential to ensure that they operate as efficiently as possible. In this article, we'll explore five ways to increase the efficiency of your industrial boiler, helping you to reduce operating costs, improve sustainability, and enhance p...
Using artificially softened water in the heating circuit with your boiler can potentially cause issues and is not recommended.
Artificially softened water contains high levels of sodium ions, which can cause corrosion of the boiler and other components in the heating system. This corrosion can damage the boiler and other components, leading to leaks and reduced efficiency.
In addition, artificially softened water can cause problems with water pressure and flow rate, which can i...
Gas-fired boilers use gaseous flammable gases (including liquefied combustible gases) as fuel. These gaseous fuels have relatively higher calorific value and less pollutant emissions, and are gradually becoming popular among corporate users.
Drying the moisture in the fuel of a biomass-fired boiler is important to ensure efficient combustion and prevent issues such as fuel bridging, clumping, and poor boiler performance. Here are some methods that can be used to dry the moisture in biomass fuel:
1. Sun drying: This method involves spreading the biomass fuel, such as wood chips or sawdust, in a thin layer in a sunny, well-ventilated area. The sun's heat and wind will help to evaporate the moisture in the fuel.
2. Fo...
