Boiler is a kind of thermal energy conversion equipment composed of drum and furnace. It uses fuel combustion to heat water into steam or hot water to provide power for production or help auxiliary production. With the continuous improvement of industrial manufacturing technology, boiler's control has also changed from the traditional full manual operation to the present automatic intelligent control.
Selecting a gas-fired boiler for heating a 200,000 m^2 area involves several considerations to ensure efficient, reliable, and cost-effective operation. Here’s a structured approach:
1. Determine Heating Demand
First, calculate the total heating demand of the 200,000 m^2 area. Heating demand varies based on climate, building insulation, usage, and local standards. A rough estimate for moderate climates is 100 W/m^2, but this can vary.
2. Choose Boiler Type
Decide on the boiler type. Fo...
A well designed and operated biomass boiler burning fuel within the specification of the boiler should not produce any smoke, but black smoke may be produced if the fuel is too wet for the boiler. All biomass boilers produce some oxides of nitrogen (NOx), particularly nitrogen dioxide (NO2). While NOx emissions from gas boilers have been reduced significantly in recent years through the use of low NOx burners which burn at a temperature slightly below that at which NOx forms, the nature of biomass combustion, and the need to ensure the complete combustion of wood gases, means that combustion takes place at a temperature where atmospheric oxygen and nitrogen can chemically combine. The better the quality of the combustion control system on a biomass boiler, the lower the NOx emissions will be. In general, biomass boilers produce less NOx than oil boilers. Biomass boilers do not produce any oxides of sulphur (SOx).
In the whole drying process, we should pay attention to gradually increasing the temperature instead of burning by raging fire; regularly checking boiler's water level and keeping it within the normal range; keeping the flame balanced in the furnace. In addition, we also should properly open the drainage valve and maintain the water level, regularly record the flue gas temperature to control the rise of temperature and high temperature and keep the temperature within the normal range. In general, under these conditions, boiler’s drying quality can be ensured.
The pollution discharge of the biomass-fired boiler is less than the coal-fired boiler. It is also necessary to deal with the exhaust gas of the biomass-fired boiler to meet the national standards before boiler ignition and operation.
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.
Discharging high-temperature flue gas generated by a biomass-fired boiler efficiently and safely is crucial for boiler operation, environmental compliance, and energy recovery. These gases, if not handled properly, can lead to energy inefficiency and increase the emission of pollutants.
