industrial bearing pressure boiler

Boiler not cleaned What are the dangers industrial bearing pressure boiler daily to do the cleaning work, the scale should be cleaned, so as to avoid unnecessary losses, which harm the following look at the boiler scale: 1, causing the metal heating surface of boiler overheating, damage to the boiler, shorten life. Boiler heating surface green scale, cooling the metal wall surface is affected, resulting in increased wall temperature, the mechanical strength of the metal material is reduced, resulting in heating surface deformation, bulge, burst pipes and the like, or even a serious explosion. Damage to the boiler, affecting life. 2, to reduce the evaporation boiler, reducing the thermal efficiency of the boiler, waste of fuel. The presence of boiler scale is equivalent to an additional layer of resistance heating surface, because the scale is lower than the thermal conductivity of steel is large, hindering heat transfer, the heat released by combustion of fuel can not be effectively transferred to the water, water vapor can not be measured heat , with the exhaust gas side of heat is lost, and therefore to reduce the boiler output, fuel waste. According to statistics, the junction of a millimeter scale, about 2 to 3% waste fuel. 3, disruption of normal boiler water circulation, forced shutdown maintenance, increase maintenance costs. After water boiler fouling, reduced flow cross-section of the inner tube, the flow of power to increase the water cycle, even when serious completely blocked. Disrupted and boiler water circulation pipe burn, forced shutdown for maintenance. Waste of human and material resources, resulting in losses. In short scale great harm to the boiler, the boiler can not be safe and economic operation. Explosion-proof doors too heavy or inadequate pressure relief area; Exhaust Gas Temperature unreasonable. Caused by poor management of the boiler running water or boiler filled with water; poor management of water quality caused by boiler scaling; oxygen poor metal heating surface corrosion; sewage is not timely boiler water alkalinity is too high; adjust the boiler is not timely adverse atomization, incomplete combustion, flame instability or skewed; the fault itself or combustion burner system failure caused by boiler flameout. In summary, boilers and process design supporting improper installation, operation mismanagement can cause accidents occurred boiler, enterprises and workers to bring the loss of life and property. As long as we understand and master the hidden laws of boiler accident, strict boiler design, boiler installation, boiler management, and constantly improve and perfect the boiler management method, you can while avoiding disadvantages, to avoid boiler accident.

Recently, Jinan City, Shandong Province People's Government issued and implemented the "2018 Beijing and Tianjin and the surrounding regions - 2019 autumn and winter tackling air pollution comprehensive management action plan" to inform the implementation of the program, requires the consolidation of ambient air quality improvement achievements, promote air quality continues to improve. On October 1, 2018 to March 31, March 2019, and all the city county fine particulate matter (of PM2.5) mean concentrations fell more than 2%, severe pollution and over several days up declining.

"Implementation plan" will be based on four construction industry, energy, transport and land use optimization adjustments to promote clean heating, public transferrin, enterprises mentioned standard upgrade, dust remediation, focusing on the consolidation of "scattered pollution" enterprise comprehensive rectification results, ruthless grasping diesel trucks, industrial furnaces and rectification of volatile organic compounds, heavy pollution to the implementation of the weather in autumn and winter peak load shifting production to strengthen joint prevention and control among regions, strengthen law enforcement supervision.

1, continued implementation of the total coal consumption control, strict implementation of national, provincial coal consumption reduction of about alternative work arrangements, and the development of alternatives seriously implement the Jinan City, the work reduction of coal consumption, coal consumption control tasks break down into individual counties, total coal consumption to achieve a steady decline. 2018, the city's total coal consumption control in less than 17.14 million tons.

2, effectively promote clean heating to the town (street) or the county as a unit as a whole. As of 2020, the city's pre-season heating living and improve the basic motivation for heating coal for alternative tasks, to develop a three-year implementation program to determine the annual task of governance. Taking into account the agricultural greenhouses, animal building bulk coal governance and to proceed with energy-saving buildings to improve energy efficiency. The county should proceed from reality, according to local conditions, reasonably determine the transformation of technical route, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, and actively promote the use of solar thermal and centralized biomass utilization; adhere to highlight focus, give priority to urban life and motivation for heating gas demand, priority to promoting the urban bulk coal cleared. Gas will adhere to the reform, to change the electric set, on the basis of priority to the protection of residents in 2017 has started "coal to gas," "coal to electricity" project on gas electricity, gas and new year according to the actual supply and heating period the ability to reasonably determine the residents' coal to gas, "" coal to electricity "households; insist on legislation after the break, substitution of gas for coal to electricity instead of coal and other alternatives, in the implementation of air power is not the case, the original heating facilities will not be removed. In accordance with national, provincial requirements, to complete the clean winter heating construction tasks 33000.

3, complete replacement of the bulk coal areas to be designated as high-pollution fuel combustion zone ban in accordance with the provisions, shall not be burning coal for use again. Severely crack down on sales of low quality coal combustion, to ensure the quality of coal used in line with national and local coal quality standards.

Procedure industrial bearing pressure boiler boost? Boiler boosting steps are as follows: 1 when the pressure was raised to 0.05; when 0.1MPa, rinsing drum water level gauge. 2. When the pressure was raised to 0.15; 0.2MPa time, closing the drum door air, dehumidifiers hydrophobic door header. 3. When the pressure was raised to 0.25; 0.3MPa when, sequentially lower header sewage water wall door, note drum water level, the boiler feed water should be closed drum, economizer inlet to the recirculation door. 4. When the pressure was raised to 0.3MPa, the notification instrument (h) flushing pipe tables, the contact main steam turbine door open doors steam heating pipe, when the pressure was raised to 0.6; when 0.7MPa, the main valve fully open close the bypass valve. 5. When the pressure was raised to 1MPa, thermal notification into water gauge. 6. When the pressure rose when 2MPa, steady pressure to the boiler conduct a comprehensive inspection found irregularities should be stopped boost, until the fault is cleared, continue to step-up, pressure increased to 2.4MPa, sewage regularly turn. 7. When the pressure rose to 3; when 3.4MPa, rinse Water Level Indicator, notification chemical laboratory quality soft drinks, and equipment to conduct a comprehensive inspection. Boiler and steam conditions

Natural gas steam industrial bearing pressure boiler operation is automatically interrupted abnormal combustion burner gas steam boiler advantage is supplied by well-known manufacturers in the world, burn automatically stop controller in accordance with instructions, a separate control box has a number of security, performance, security and stability, maintenance rate. Advanced steam boiler automatic controller, Chinese LCD screen, man-machine interface, users simply relaxing setting, the boiler is able to start and stop according to user requirements, load regulation, automatic water supply and other automated operations.
