use of coal in steam boiler

Advancing the ignition point of coal, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal. 2. The air supply and reasonable regulation. In Grate, vibration stove, oven and forth, depending on the characteristics of the combustion process, reasonable air, to promote combustion furnace is very important. As the chain furnace, with grate the fuel is kept in motion, occur sequentially ignition, combustion, burn various stages. Along the longitudinal direction of the combustion grate stages, the partition, the amount of air required in the grate longitudinal direction is different. In the preheating zone of the head and the tail of burnout grate stage, small air requirement in the middle stage of combustion grate, the air amount required.

Thirteen Five release plan indicates that China's move towards green development pace firmer, Beijing SASAC Building Materials Service Center from its start, the use of green boiler heating for low nitrogen as the primary task before the onset of winter. SAC Building Materials authorities after preliminary investigation and after the screening, the other fast boiler R & D experience in the field of boiler cleaning two decades expressed appreciation can, in August 2017 signed a five Thalia T6 series one boiler and two vacuum with fast Boiler condensing gas boiler products contract.

Boiler structure have? The whole structure, including boiler and boiler auxiliary equipment of two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler.

Factors which influence energy-intensive industrial boiler energy-intensive industrial boilers factors influencing factors which have high energy consumption of industrial boilers which have 1, energy consumption is low management level industrial boiler is too large, are long-term presence of many companies in the current . On the one hand understanding of the enterprise energy conservation boiler is still not sufficient, on the other hand the energy management level is still at a low level, and even some companies even the most basic measuring instruments are not equipped. In order to reduce operating costs, many companies have to buy the old boiler use, lack of components purchased fuel means of inspection. Even in the case of raw coal screening is not performed, it is directly put into production use, it is difficult to ensure full combustion of coal. Not only the thermal efficiency is low, but also resulted in a waste of fuel. 2, heat recovery is poor combustion is incomplete, the situation is the high rate of heat loss is extremely common in industrial boilers used in the process, saving the main parameters of the boiler will be exceeded. Economizer function is to heat energy recovered, but in actual use, heat recovery efficiency is very low. In this case, do not use a lot of boiler economizer direct altogether, inevitably produce exhaust gas temperature is too high. Meanwhile, return the device and steam condensate recovery, it has not been fully appreciated and better use, some are put to use in the boiler after installation, and did not take appropriate measures to deal with poor recycling effect. 3, lack of effective supervision of the level of energy service work, depends largely on the level of experience and technical personnel. But in practical terms, due to the lack of technical personnel, resulting in the energy service work at the level of the low. Various enterprises produced energy-saving products with high imitation, coupled with the lack of effective supervision of energy-saving measures, resulting in the entire market of energy-saving products more confusing. The effect of not only energy-saving effect is not ideal, and to transform the poor, the performance of energy-saving products remains to be greatly improved. Market confusion, vicious competition phenomenon has not been fundamentally curbed.

Types of Coal | Boilers - Technical Information

There are various types of coal, from anthracite with its high carbon content to bituminous coal, subbituminous coal and lignite (brown coal), an even younger coal. Power generating equipment needs to be optimized for these different types of coal.
