full automatic biomass pellet low pressure steam boiler
Steam boilers What is the function? Too much in the form of full automatic biomass pellet low pressure steam boilers, took an ordinary four tons fast load steam boiler, for example. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Works steam boiler water is heated and converted to steam in the steam drum, the fire gives off heat in the furnace. Let me talk boiler, say the pot. This boiler is a water-cooled drum boiler. Around the drum in the two regions is provided two return tubes pyrotechnics, smoke box and in front of the drum to turn back. In the boiler drum and the lower connection between the tank, a downcomer and a cooling pipe, constituting the framework of the combustion chamber. An upper drum provided with a vapor separator, in order to reduce the outflow of water from the steam. Heating surface of the pot to the drum, and a lower cooling pipe pyrotechnic tube. A combustion section and drive means consisting of a chain grate, a combustion chamber pot grate frame composed of frame. It is surrounded by refractory material. By the combustion of the coal into the coal hopper, the thickness of the coal seam is controlled by the gate, while the air is sealed in front. Blast into the lower part of the combustion chamber is the place, this big boiler resistance, it is necessary to force the blast. Burning ash through the rear grate Eagle iron is discharged, and the outside of the furnace through the slag discharged from the device. Smoke from the rear of the boiler, the boiler return pipe from the first pipe, the second pipe from the reflux to the back, and then enters the precipitator ash is then discharged through the chimney draft fan. Induced draft fan is not only the smoke emissions, but also the negative pressure necessary for operation of the boiler. Steam boiler is a pressure vessel, the safety device is essential. Basic boiler water level gauge, pressure gauge, safety valve, thermometer, water can be added at an upper portion of the electric pump pressure, when the pump power and steam may also be used. Boiler water must be softened, and water treatment equipment.
How does the CFB boiler work
CFB technology burns fuels without fire or burners in the furnace but through a process of fluidization mixes the fuel particles with limestone which captures the sulfur oxides that are formed and the low temperature reduces nitrogen oxide formation. The limestone and fuel are recycles multiples times which increases both the efficiency of producing high quality steam to produce power and also reduces pollution due to its ability to burn fuel in a clean way than the conventional processes. Circulating fluidized bed technology(CFB) also offers the flexibility of using both coal as well as biomass fuels.
National response to control air pollution and maintain policies favorable ecological environment; effective control of thermal power, steel and other key industries, the total amount of atmospheric emissions of major pollutants, Ningxia implementation of thermal power, steel and other industries, especially air emission limits for pollutants in the metropolitan area of Yinchuan.
In particular emission limits refers to higher standards than the national emission of pollutants, more stringent emission requirements; implementation of special emission limits, implementation of key industries mentioned standard transformation is one important way to reduce pollutant emissions. Yinchuan City metropolitan area including Yinchuan, Shizuishan City, Wuzhong City Litong District, Qingtongxia City Administrative Region and Ning Dong Energy and Chemical Base (core area). Perform particularly air pollutants emission limits in all of these areas of thermal power, iron and steel, cement, petrochemical, non-ferrous metals, chemical industry, coal-fired boilers and sulfur dioxide, nitrogen oxides, particulate matter.
Since the execution time is tentatively scheduled for January 1, 2019, for the present, China has not yet specified air pollutants emission limits in particular industry, to be the relevant standards or modified, re-implemented.
For enterprises, especially not achieve emission limits of air pollutants, the government has formulated a series of remediation measures, the relevant enterprises to effectively assume responsibility for the theme of pollution control, ensure the completion of the task within the stipulated time. For within the specified time still can not meet the requirements of enterprise and equipment, the relevant departments will be severely punished according to law.
Biomass fired full automatic biomass pellet low pressure steam boiler has features of less consumption and eco-friendly during its service time. Biomass fired steam boiler can be pided into different types according to its different fuel such as bagasse biomass fired steam boiler, coconut shell biomass fired steam boiler, palm husk biomass fired steam boiler, rice husk biomass fired steam boiler, sawdust biomass fired steam boiler, wood biomass fired steam boiler and so on. In Philippines, there are a lot of bagasse, rice husk, coconut shell each year. Thus, Bagasse biomass fired steam boiler are going to be more and more popular in Philippines market.
