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...
Coking of biomass boiler is a very complicated physical and chemical process, and the reasons for coking are as follows:
Analysis of coking in the combustion of biomass-fired boiler
(1) During combustion, the temperature of fuel layer is higher than the softening temperature of ash, which is an important reason for slag formation. Under the deformation temperature of the ash, the ash particles generally do not form slag, but when the softening temperature is reached, the eute...
The boiler manhole-lids are mounted from the inside of the boiler so that the boiler pressure will help to keep them tight. Hence the manholes have to be elliptical in shape to make it possible to take the lid out from the boiler.
Prepare relevant technical data, including technical data of boiler manufacture and installation, boiler use registration data, boiler operation records, water quality test records, repair and modification records, accident records and previous inspection reports;
A hot water boiler should be thoroughly inspected at first, including the accessory pipeline. Close the drain valve and open the gauge cock to discharge the air in the boiler.
Boiler feedwater treatment system includes two parts: pre-desalination system and ion exchange desalination system.
The pre-desalination system includes ultrafiltration system, reverse osmosis system, dosing system, chemical cleaning system, compressed air system, etc.
The ion exchange desalination system includes ion exchange system, acid-base regeneration system, compressed air system, wastewater neutralization treatment system, etc.
The boiler feedwater treatment methods ar...
