fully automatic 7 bar oil fired steam boiler

Principles of fully automatic 7 bar fired steam boilers and solutions hydraulic external gear: told you about the principles of steam boilers and solutions for steam boiler hydraulic external gear in accordance with the fuel (electricity, oil, gas) can be divided into electric steam boilers, oil steam boiler, gas steam boiler three kinds; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler compact than a single, double return of the vertical structure, a large steam boiler plurality of three-pass horizontal structure. If the classification according to top standards, in the form of steam boilers on the lot, would like to give an ordinary packaged boiler say four tons vapor. 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 combustion section and drive means by a chain grate, a combustion chamber together with the pan rack frame formed on a grate composition. Four weeks envelope refractories.

There are many types of power plant boiler such as biomass power plant boiler, gas power plant boiler, oil power plant boiler, CFB power plant boiler and so on. However, when comes to the term of cost, coal fired power plant boiler is the most popular either in developed countries or in developing countries. Zimbabwe is rich in coal reserves and it has 30 billion tons of coal in 21 known deposits that could last for over 100 years, therefore, the coal fired fully automatic 7 bar fired steam boiler in power plant has earned great popularity in Zimbabwe.

Behind honor, it is thousands of times persist and exploration. Keep trying, and failed to improve, we have a number of scientific and technological problems. The launch of China's first low nitrogen boiler and stable operation in 2014, Beijing Huairou APEC venue for the realization of "APEC blue" to contribute their part. Respond positively to national policy, contribute to the cause of environmental protection. Group focus on lower nitrogen oxide emissions, a low nitrogen introduction of multi-type boiler. Existing "Thalia", "Willie sharp" and other series, the successful implementation of nitrogen oxide emissions below 18 mg / cubic meter, this data is far below the national existing standards (such as the most stringent in Beijing the implementation of 30 mg / cubic meter standard), is widely used in national important organs of the CPC Central Authority, the national Tourism Bureau.

According to fuel (electricity, oil, gas), oil-fired gas boiler can be divided into three kinds: electric fully automatic 7 bar fired steam boiler, oil-fired steam boiler and gas-fired steam boiler. According to the structure can be divided into vertical steam boilers, horizontal steam boilers, small and medium-sized steam boilers are mostly single, double-return vertical structure, large-scale steam boilers are mostly three-way horizontal structure. The following is the boiler pressure fire shutdown time more than 6 hours, the boiler main steam valve should be closed after a period of pressing fire, opening the superheater outlet header drain valve, to cool the superheater. If the air pressure rises after the main steam valve is closed, it can be used to lower the pressure of the boiler by feeding the water into the boiler and simultaneously discharging the water. Press. When the boiler resumes operation, it needs to go through the pressure rise and protect step 2. There is still steam pressure in the pot during the shutdown period of the pressure fire, so it is still necessary to pay attention to monitoring and make the boiler keep the allowable water level 3, the boiler with cast iron gas saving gas, after the boiler stops feed water, The gas-saving flue baffle shall be closed, the side-hearth baffle opened or used in the circulating pipeline to stop the water temperature in the gas-saving area exceeding the specified value of 4, the proper discharge shall be carried out during the shut-down of the furnace under pressure fire, and the sediment in the furnace shall be excluded. The operation of circulating water pump should not be stopped immediately after the furnace shut down. The circulating water of network should be kept circulating in the system for a period of time, and the water temperature of boiler outlet should be lowered below 50oC. The operation of circulating water pump can not be stopped until the operation of circulating pump is stopped.
