What is the burning of the boiler?
The boiler burning is the study of how fuels are burned in boilers that heat water for steam. There are many applications for steam boilers, including heating of the chemical process, steam heat for buildings and hot water and steam that controls electric turbine generators. Burning is a reaction of oxygen fuels in the air to create a heat used for steam production. When the fuel is sprayed or atomized into a boiler with air, the mixture may ignite the ignition coil or a small pilot flame. Burning releases a large amount of heat, some of which heat water on steam and some are lost due to radiation and loss in smoke. The radiation is an infrared heat loss that occurs from the hot boiler to the cooler room. Smoking losses are heated gases that are ventilated from the boiler through its smoke or ventilation.cy burning of the boiler. The main problems to be considered are the efficiency of combustion or how well the fuel and air mixtures burns and how to minimize heat losses.The famous heat loss can be minimized by the correct insulation of the boiler and steam pipes. The design and controls of the boiler can be used to maximize combustion efficiency.
The boiler combustion surface usually has a tube containing water and a pair passing through an open box that can contain burners and controls. Tube design can improve efficiency using multi -band systems. The water tubes entering the boiler may first pass through the smoke gas zone, which takes part of the waste heat and preheat water. The pipes can then pass through the combustion zone more than once to fully use the combustion heat, which also improves efficiency.
The efficiency of the combustion of the boiler for air and fuel mixtures is decisive for the proper operation of the boiler. The molecule fuel the theoretical amount of oxygen to be completely burn, but in fact it is necessary to excess oxygen due to various losses in the combustion zone. The air isAbout 21 percent of oxygen, so unburned nitrogen in the air must also be heated in the boiler and venting with smoke. This also affects the efficiency of the boiler and creates nitrogen compounds that have been associated with acid rain and smog formation.
too much oxygen reduces the temperature of the boiler burning, it can create some undesirable pollutants and requires the fuel to heat oxygen and nitrogen that are not used. Lack of oxygen can reduce the boiler efficiency and create soot and other by -products that can damage the boiler over time. Research has found that monitoring of oxygen and combustion gas concentrations in the smoke gas and maintaining the correct temperature of the smoke bathing can optimize the boiler performance.
Smaller boilers can be treated manually using smoke gas sensors and smoke gas thermometers, but many boilers can benefit from automatic Contryols. The boilers may not work at one operating point, but will have different steam requirements or operating conditions, which is Manua settingimpractical effectiveness. Older boilers can be equipped with electronic controls that provide feedback on air and fuel input pumps to provide the best combustion ratio.
