Pressure chinese coal fired chain grate steam boiler shutdown fire you do not know the techniques and precautions steam boiler refers to water heated to a certain temperature parameters and the production of industrial steam boiler, the water in the steam drum is heated to become vapor, fire emits heat in the furnace, It is the principle of the steam boiler. Steam boiler belongs to special equipment, design, processing, manufacturing, installation and use of the boiler must be supervised by technical supervision departments, users only get to use the boiler permits to use steam boilers. Fire pressure steam boiler shutdown is interrupted by slowly burning until the load drops to zero until a planned shutdown. Specific steps are as follows: 1, to reduce boiler load, according to the length of time of shutdown, the seam thicker, the thickness is generally not more than 200 mm, suitable to accelerate the speed of the grate. 2, the distance to the thick seam slag is about 1 mm grate stop rotation of the drum is stopped, the operation of the induced draft fan, blowing off a small segment of the regulating plate stopper and dampers qs, relying on natural ventilation to maintain coal lean-burn, the sewage, boiler water level will rise to the maximum allowable level. If the fire burn coal gate, grate can be switched on again, the gas will move back some distance. 3, the recovery boiler needs to run, as long as the opening lead, a blower, to adjust the smoke, and the wind baffle plenum segment adjusting the opening degree of the shutter, the adjustment of combustion steam boiler seam thickness to be normal, start grate, to resume operation .
Select the first chinese coal fired chain grate steam boiler to know what parameters? Steam boilers have the following main parameters: 1, Rated evaporation Rated evaporation is power steam boiler, steam boiler is the most important parameter, usually expressed in tons evaporation, that is, we usually say how many tons of boiler. 2, rated steam pressure rated steam pressure means that the steam pressure generated in the steam boiler, generally expressed in MPa or kg. 1MPa is 10 kg, like laundry, all hospitals, factories and the like conventional steam occasions the general use of low-pressure steam 1.0MPa or less. Only when using steam as a power to require the use of high-pressure steam. 3, where the steam temperature of said steam temperature, refers to the temperature of saturated steam. Saturated steam pressure and steam temperature are corresponding. Temperature of saturated steam at a pressure of 1MPa 184 ℃. 4, gas / oil / coal consumption fuel consumption is an important indicator of concern when choosing a steam boiler, which is directly related to the use of the running cost of the boiler. In the operation of the boiler, the fuel cost is very impressive, if just considering the purchase cost of buying a cheap but high energy boiler, which led to the late high operating costs, certain that it will be wasted. 5, the thermal efficiency of fuel consumption with the boiler thermal efficiency of boilers is inversely proportional. The higher thermal efficiency, lower fuel consumption of the boiler. Boiler thermal efficiency expressed as a percentage, the value is a more intuitive. 6, the boiler operating weight, size or location in the election of the steam boiler, it should find the place whether the load per unit area can withstand the weight of the steam boiler, and if there is enough space to place the steam boiler maintenance and reserve space.
Two of the country this year, the NLD Central Democratic National Construction Association Central and made a number of proposals, to speed up the clean and efficient use of coal mine environmental governance has become a hot topic.
NLD central in the proposal pointed out that China's energy structure adjustment should take Duocuobingju way, multi-pronged approach in phasing suppress excessive coal consumption, promote clean and efficient use of coal, etc., it is necessary to focus on environmental protection, but also to resolve the coal system pressure generated by the financial industry, but also pay attention to the industry employment situation of people's livelihood and social stability.
National Bureau of Statistics recently revealed that total energy consumption in 2018, 4.64 billion tons of standard coal, up 3.3 percent over the previous year, of which coal consumption increased by 1.0%. According to statistics, China's coal demand had reached 4.24 billion tons high point in 2013. From 2014 to 2016, coal consumption declined for three consecutive years, from 2017 to 2018 and began to grow, demand for electricity is the most important factor in the growth of coal consumption in our country return to growth.
NLD central in the proposal put forward, to change the traditional extensive coal utilization, promote clean and efficient use is an inevitable choice to realize energy structure adjustment "soft landing". As most of the early years of huge capital investment in the coal industry to achieve through bank credit, the current coal production capacity is still excess capacity, low coal prices, in this case, it should gradually promote the adjustment of energy structure through technology, etc., should not too quickly, leading to financial system pressure increases, the pressure to raise employment and livelihood.
Proposals suggest that the development of coal-based regional energy center, to achieve energy efficiency an "electricity, gas, cold, heat, water" comprehensive energy plan overall, a substantial increase in thermoelectric projects. Forced to upgrade enterprise technology through carbon taxes and sewage charges, increase the proportion of clean energy use. Regional Center for Alternative Energy Development dispersed small boilers. Accelerate the development of clean coal conversion industry, the direct liquefaction of coal, industrialization indirect coal liquefaction, coal gas, coal, ethylene glycol and other technologies to increase support development efforts.
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.
Chain traveling grate is widely used in many countries for long time. Ash content plays an important role for chain grate. Coal to be used for chain grate must contain at least 10% ash in order to from a protective layer between the chain grate surface and the fuel coal.Get a Quote
