Note: The cleaning cycle gas-fired specification for industrial boilers

Large boiler: 2 ~ 3 years cleaned once; Medium Boilers: 3 to 5 years washed once; small boiler: 4 to 6 years washed once.

To complete the "clean winter heating pilot cities in northern areas," the goals and tasks, Jinan Municipal People's Government issued the "Jinan City" pilot cities for winter heating cleaning northern "three-year implementation plan (2017-2020 years)." "Program" is mentioned, three-year pilot period 59 key projects a total investment of 27.3 billion yuan, 2.1 billion yuan from the central government funds, municipal funds 5.8 billion yuan financial support to attract social capital of 19.4 billion yuan. Six technical work in accordance with the deployment path, focusing on elimination of coal-fired specification for industrial boilerss, clean the deep geothermal heating, urban and rural construction and other clean energy alternative to lead technical projects, improve the maintenance of post-operation, promote clean winter heating work in an orderly manner.

Focus on the implementation of urban and rural clean energy alternatives. In the vast rural areas and central heating uncovered areas, in accordance with the enterprise-based, government promotion, residents affordable policy, local conditions, the use of alternative energy classification implementation. Urban and rural clean energy alternative to task a total of 48 projects, plans a total investment of 6.272 billion yuan (excluding clean coal-burning alternative to low-quality coal project), in which the central budget funds 820 million yuan, local financial and social capital invested 5.452 billion yuan. Coal to electricity which involves 19 projects, the use of alternative energy, Valley Electric energy storage, energy management contract, support clean green electricity for heating, with a total investment of 650 million yuan, of which the use of the central budget funds 250 million yuan; shed no change change clean heating, involving 95 000, in which the central government 200 million yuan.

So, what precautions do when the user has to buy electric steam specification for industrial boilers for the first time? Fast boiler for your science.

A thermal efficiency

Boiler explosion in the specification for industrial boilers explosion pressure is always weak parts of component failure, and then by the gas, water expansion due to severe water hammer pot large amount of water so that the tear propagation occur. Vertical boiler rupture, most of them in scraps circle at a lot of steam from cracks jet, flew into the sky like a rocket, likely to fly away from tens to hundreds of meters; horizontal boiler explosion, prone to high temperatures in the lower abdomen drum furnace or combustion zone above the high temperature radiant section, since the inside of the furnace, boiler most likely parallel longitudinal flew. Next, we analyze the reasons for the explosion of the boiler equipment: 1, congenital defects: design errors, force structure, thermal compensation, the water cycle, a serious error with respect timber, strength calculation, safety facilities; manufacturing error, the wrong material, not according to the drawings, poor quality welding, heat treatment, hydrostatic testing, and process specification errors. 2, overpressure rupture: high operating pressure exceeds the boiler working pressure permit the element stress than the material limit stress. Overpressure conditions often due to safety relief device failure, inaccurate pressure gauge, overpressure alarm device failure, severe water shortages and accidents caused by improper handling. 3, overheating failure: a steel sheet hot burn, reduce the strength member caused damage. When the boiler water is generally dry, thick fouling, boiler water, there is reason to cause foreign matter or grease fall within the drum asbestos rubber plate or the like. 4, and burst patterns from slot: receiving element alternating stress, fatigue cracks, but also by the combined effects of corrosion, resulting in a groove-shaped thinned. 5, water hammer damage: the system caused by improper operation soda water hammer, so that the additional element by a strong stress failure. These are the causes of boiler explosion, I believe you must have learned a lot of knowledge of it, I hope this can help you to better avoid the occurrence of such phenomena, to ensure the safety of the work carried out.
