Oil-fired boilers include oil-fired water boilers, oil-fired hot water boilers, oil-fired heating boilers, oil-fired bath boilers, oil-fired steam boilers and so on. Oil-fired boilers are boilers fueled by light oil (such as diesel oil, kerosene), heavy oil, residual oil or crude oil. Compared with gas-fired boiler and gas-fired boiler, oil-fired boiler runs more economically than electric heating boiler and is more convenient to use than gas-fired boiler. With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired boilers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas fired boilers, etc., electricity Heating boiler operation is the most expensive, gas-fired boiler needs to be opened with gas pipeline, then, if there is no natural gas pipeline, but also hope that the operation cost of the boiler is low, only the choice of fuel-fired boiler. Oil-fired boiler is heated by burners, fuel atomization effect is good, fuel combustion is full, chimney can not see black smoke, so fuel-fired boiler green environmental protection, efficient and energy-saving. After the fuel oil is sprayed into the furnace, it is very easy to mix with air and burn rapidly and exothermic rapidly. Compared with coal-fired boiler with the same parameters and capacity, the thermal strength of furnace volume can be doubled. However, in order to reduce the heat load in the combustor zone, the water wall tube in this zone is avoided. Because of the overtemperature, the furnace volume is only reduced by about 1 / 3. Moreover, because the ash content in fuel oil is very little, it will not be slagging on the convection heating surface, so the flue gas temperature at the furnace outlet can be as high as 1300 ℃, and the pitch between tubes on the convection heating surface can be reduced to increase the flue gas flow rate, thus the heat transfer coefficient on the heating surface can be increased. Save heating area and steel. In order to prevent spontaneous combustion of carbon black oil scale on economizers and air preheaters, steam soot blowers should be added to these parts to keep the heating surfaces clean. At the same time, because the fuel oil does not form coke slag, the membrane water-cooled wall can be used to form a micro-positive pressure (500 x 1000 cow / ml). A boiler. It can save the draft fan, only the fan can exhaust the flue gas out of the furnace. If the whole shell of the boiler is made of thick steel plate, it can also be made into a positive pressure (0.3 ~ 0.6 MPA) boiler, which can make the whole structure of the boiler more compact, and is more used in the gas-steam combined cycle generator set.
The main purpose of the boiler is the main purpose of what the boiler: Boiler national economy is an important energy supply equipment. Electrical, mechanical, metallurgical, chemical, textile, paper, food and other industries, as well as industrial and civil heating boiler needs to supply large amounts of heat. Boilers using fuel combustion energy released or other energy to the working fluid (heat carrier intermediate) is heated to a certain device parameters. For heating the water to make it into the boiler steam is known as steam boilers, also known as a china fired steam generator for sale for heating water to make them more water into the boiler temperature, known as the hot water boiler for heating of Heat Transfer Fluid It called boiler organic heat carrier boiler.
Food factory steam boiler water shortages how food processing plant steam boiler water shortages how to deal with? Food factory steam boiler water shortages how to deal with? Steam boiler operators need to take what method to determine the boiler water, whether or not time to add water. When the steam boiler operators should find the boiler water do? When the china fired steam generator for sale water level drops below the minimum water level when the water level gauge can be directly color display all the color lights vapor. Low water level alarm number appears at high level and low level alarm. From this moment the low water level interlock, vehicle suspension. If the superheated steam temperature sharp rise performance, a steam outlet temperature higher than normal body. An exhaust gas temperature of the boiler increases. Small flow of water steam flow ratio. If a pipe rupture or economizer, should urgently add water.
Our environmental management efforts continue to increase, located in Wuhai City of Inner Mongolia is also actively respond to national policies, by removing, shutting down non-compliance of the measures within the jurisdiction of coal-fired boilers, etc., to improve air quality within the city.
Recently, a reporter to follow the staff Haibo Bay Area environmental monitoring brigade, examined the case of shutting down coal-fired boilers in rural areas. Trinidad town in Wuhai unity Village, coal-fired boiler is the main source of heat in the village residents, schools, hospitals in the town and airport, but because they do not meet environmental requirements, the boiler has been officially shut down at the end of 2018. Haibo Bay Area Environmental Protection Agency environmental monitoring battalion to us to: "Removing the boiler is 20 tons of steam coal-fired boilers, each heating season about to burn more than 3,000 tons of coal in accordance with the municipal government requirements. within the deadline 20 tons of steam boilers to be all removed, replaced with clean energy. since November 2018, this block of sea area has access to a central heating all children. "
So far in 2013, Wuhai City in strict accordance with regulatory requirements grid, earnestly implement the responsibility of inspectors on-site supervision, and has eliminated 20 tons of steam coal-fired boilers for heating and tea bath furnace 791 units, of which 2018 out of 58 units. Meanwhile, municipal and district environmental protection departments at all levels to increase on-site law enforcement and ensure that the boiler is no longer out of the resurgence. Up to now, it has no built-up area of Wuhai City and 35 tons of steam coal-fired boilers to achieve a stable discharge standards.
Gas used in high efficient natural gas boiler is a very common source of energy and can be transported and transported over long pipes, so that it is a good solution to long-haul fuel transportation. high efficient natural gas boiler will not produce ash after burning, impurities, corrosive gases. And industrial use of natural gas ignitionGet a Quote
