industrial fuel oil or gas steam boiler

WNS type gas industrial fuel oil or steam boiler system control principle: ①, after WNS type gas steam boiler on the power switch, click on the pump control switch open position, after boiler feed water rises to the normal position, click-burner power switch, clicking the start button, the control system power is on, the burner into the working state, according to the operation program for the controller, to be re-ignition burner fires into the combustion state, the boiler enters normal operation this stage. ②, high output level when the water level rose to a high level alarm signal indicator light, when the water level rises to the pump stops running + 25mm, the water pump when the water level falls -25mmm automatic restart, when the water level falls -50mm, outputs a low level alarm indicator light, with bell sound, and cut off the power to the controller to achieve protection shutdown, -75 mm when the water level falls, the output signal of low water level indicator light. ③, when the pressure is raised 0.73MPa, the output signal of the first indicator light overpressure, combustion conditions and off the controller circuit, the controller stops the shutdown. Output when the pressure rises above a second overpressure 0.75MPa signal issued bell sound, alarm and cut off the power supply control system implemented emergency stop. Regulating the pressure when the pressure exceeds the upper limit, the controller output signal of a small fire fire closed valve, a valve to open the small kerosene ignition burner. When the lower limit pressure drops below the regulated pressure, the controller outputs the fire signal to open fuel valve fire, the fire to burn. ④, after the failure of the burner failure occurs, the burner control valve is automatically shut down to stop the oil combustion.

A few days ago, Datong City, Shanxi Province, issued a "decisive battle 300 days, to enhance the" Datong blue "plan", combined with ongoing Shanxi Province: innovation, work for "the great debate, promote green development, and constantly improve the level of ecological civilization, achieve a good number of days 300 days throughout the year for more than two goals. details are as follows.

1, aspects of the transition. On the basis of the regulation last year, continued to carry out "dirty scattered" enterprise rectification work. According to industrial policy, industrial layout planning, as well as land, environmental protection, quality, safety, energy consumption, etc., to carry out an intensive investigation, the establishment of management accounting. In accordance with the principle of "first stop after the rule", the implementation of classification disposal, have been banned "dirty messy" business, appears to prevent the resurgence of the phenomenon.

2, corporate governance aspects. Industrial pollution discharge standards to strengthen the comprehensive management of enterprises can not achieve full compliance, should be taken to stop production remediation. Full completion of key industries pollution remediation work, on the basis of the city's nine power companies that run on ultra-low emissions stable, GD Datong Power Generation Co. Ltd. within the scope of the built-up area of ​​the city and Datang International Yungang Thermal Power Co., Ltd. completed before the end of the colored Amidst the governance feasibility report, we lay the foundation for next year colored misty rain governance. December 30, 2019, to carry out ultra-low emissions and chemical industry, iron and steel, nonferrous metals, cement industry, especially emission limits transformation; completed 100 industrial enterprises fugitive emissions control, industrial furnace control 41 upgrades, 11 key industries and enterprises volatile organic compounds governance and four key industries and enterprises volatile organics management upgrade.

3, less coal ways. Insist on proceeding from reality, should be in accordance with the electric power, gas should the gas, should the coal coal (ultra low emission), should be hot is hot, and more heating energy policy to ensure the safety of the masses warm winter. Residents living coal simultaneous implementation of clean energy alternatives. District heating flat built-up area clean 100% coverage, coverage of other counties clean heating built-up area of ​​more than 70%, 40% or more in rural areas, to proceed with the phase-out of coal-fired boilers. Renovation project to carry out ultra-low emission coal-fired boilers, October 1, 2019, 65 tons of steam coal and above and build the region (biomass) and energy-efficient boilers to complete the transformation of ultra-low emissions, low nitrogen gas boiler basically completed the transformation.

Classification and distinction and design a gas boiler, gas boiler gas boiler classified in accordance with the fuel can be divided into natural gas boilers, boiler city gas, coke oven gas boiler, liquefied petroleum gas boilers and gas boilers; according to the function can be divided into gas boiler water , gas hot water boiler (gas heating boiler comprising a boiler and bath gas), gas industrial fuel oil or steam boiler and the like; can be divided according to the structure of vertical gas boiler, gas boiler horizontal; in accordance with the process can be divided into a single flue gas boiler and tris backhaul backhaul gas-fired boiler. Second, the difference between fuel oil-fired boiler fuel boilers and gas boilers is fuel (such as diesel, oil, kerosene, etc.), fuel gas-fired boiler to gas (such as natural gas, city gas, biogas as well as liquefied petroleum gas, etc.), depending on the boiler What fuel burning device called a burner, boiler gas burner configuration called gas-fired boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference is that what fuel burners. Third, the design of the boiler furnace by the gas boiler structural design pressure, provided through the top of the large pores, the boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that coordination and beautiful form. Vertical-mounted boiler combustion at the burner, combustion of the fuel within the positive pressure furnace, baffle interposed smoke tube, slow smoke evacuation rate, to strengthen the heat exchanger, the heat furnace to ensure maximize fuel combustion water, improving the thermal efficiency of the boiler; horizontal wet back boiler full three pass structure, the length of the flue gas flow, reducing exhaust gas temperature, the whole corrugated furnace provided, so that the flame produced a strong turbulence to improve the heat transfer coefficient strength, and effectively It is prevented due to thermal expansion and contraction of metal results in a reduction of the life of the device; smoke tubes of large diameter and large pore bridge the gap, the boiler at equal time scale coating thin and easy to clean.

Henan gas boilers What are the advantages and disadvantages? Henan gas boiler is a clean burning natural gas for industrial boiler energy section of industrial production output of hot water and steam. After the recent years, increasing environmental pressures and an increasingly serious energy crisis, the government has introduced a series of laws and regulations on the promotion of energy conservation and emission reduction, to encourage new energy promotion, the gas boiler should be transported from Henan, breaking coal boiler "thriving" situation. Compared with conventional oil-fired boilers, coal-fired boiler, gas boiler Henan has unparalleled advantages, mainly in the following areas: 1, Henan artificial gas boilers and low consumption of water and electricity costs; 2, gas-fired boiler flue gas of Henan or promote condensation energy technology, it greatly enhance the thermal efficiency further, when the exhaust gas temperature Henan gas boiler is reduced to 80 degrees or less, up to 95% efficiency; 3, Henan environmental clean gas boiler, a small area of ​​the boiler, low failure rate, significantly improve the use of units on-site environment, adequate supply and lower prices, environmental requirements higher cost areas of comparative advantage of obvious; 4, due to the Henan gas-fired boiler using clean energy, so when burned does not produce soot and dust in the furnace, so the operating life than other types of boiler long. However, due to the environmental advantages of natural gas and energy in a growing proportion of supply and demand and Jiazhiguilv bound to make the country in the future and gradually it with other primary energy prices linked to float, its long-term price trend will gradually open. In addition natural gas shortages in some areas or seasonal shortages also affect the reasons for its further promotion. On the whole, the use of gas-fired boiler more good than harm Henan, Henan to promote the use of gas-fired boiler is still the trend. Van de force as a professional boiler boiler supplier, in terms of Henan gas boiler series of development and exploration, successfully developed a low nitrogen gas boiler Henan, have made outstanding contributions to technological innovation in Henan gas boiler.
