The output power of the burner should be matched with the rated output of the 3000kg fired boilers, and the shape of the flame, such as length and diameter, should be selected to suit the furnace structure. Supply the air needed for fuel combustion from the torch root to make the oil mist or gas and air mix evenly and quickly to ensure complete combustion.

New coal fire late, often appear off the fire bed fire, fire away from coal gate about 0.6 ~ 1.Om, burning furnace is not strong, high ash carbon content. For existing furnace arch structural problems, from improving fuel fire conditions, improve furnace temperature begin to transform the 3000kg fired boilers. After the furnace arch after the transformation, the people stove fuel from coal gate 0 · 3mRP fire, the fire bed combustion intense flame full of good, strong rotation. Since lowering the front arch, the arch extended, reduced to about 1 2 throat formed between the arch of the original pitch. Where the enhanced mixing flow disturbances, reorganized stream, enhanced combustion furnace, to effectively improve the temperature of the entire front region and the arch of the furnace, to reach 1400 degrees, the condition of the fuel to improve ignition. 2. The ignition point of coal in advance, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal.

The frequent attacks on haze weather since last year heralded that the atmosphere had to be managed. Coal emissions are regarded as the culprit of the formation of haze, so the coal-to-gas plan has entered a high-speed growth period in an all-round way. At present, the transformation of natural gas 3000kg fired boilers has become the hot first choice for investment environment management industry. According to reporters understand, so far for coal-fired boiler demolition and phase-out has entered a substantive phase of implementation. Since entering the second quarter, many places in the country have issued measures to remove and reform high-pollution coal-fired boilers, and a war of annihilation of coal-fired boilers has been launched in an all-round way. The correlation analysis shows that under the background of energy saving and environmental protection, coal to gas will become the next few years. As a substitute for coal-fired boilers, natural gas boilers will also usher in a high-speed growth period. In addition, the reporter learned that since the second quarter of 2013, in addition to Beijing, Zhengzhou, Xi'an has also dismantled 194 coal-fired boilers; Construction, environmental protection, municipal and other departments of Lanzhou City to reform the urban coal-fired boiler projects jointly approved, has started to demolish 83 units of 1518 steam tons, accounting for 40% of the total task of dismantling; Urumqi, Xinjiang, has put coal into the people's livelihood project as the top priority in the construction of beautiful Xinjiang; dozens of heating stations in Tibet are also actively carrying out the transformation of gas-fired boilers; Jiangsu Jiangyin, which is heavily energy-consuming, has also stepped into clean-energy applications, with 100 coal-fired boilers scheduled to be phased out by the end of the year. As a result, the coal-fired boiler gas conversion project has entered the high tide period.

Since March this year, Haidong Qinghai province to implement the central issue environmental supervision feedback coal-fired 3000kg fired boilers rectification work, speed up the production of green, zero emissions work processes, and improve air quality, to develop a series of coal-fired boilers on the rectification requirements of the program, as the initiative, strike out, to carry out rectification work in coal-fired boilers within the city, complete elimination of high energy consumption and serious environmental pollution of coal-fired boilers. Planned before the end of 2020, out of the new regulation since 2013 registered 10 tons of steam per hour and a total of 35 sets of coal-fired boilers. To date, 24 have been dismantled coal-fired boilers, the completion of 69% of the total demolition tasks.

In campaigns, the Haidong Market Authority established the Secretary for the head of the leading group, and achieve the "four guarantees" work. First, strengthen organizational leadership, promptly convene a special meeting arrangements, set up to director, head of the leading group, strict rectification requirements, compaction responsibility, division of labor, supervision and implementation, to ensure that the tasks, responsibilities, personnel, time to implement place; second is to strengthen the publicity and guidance, held a coordination will promote, publicize national environmental policy so that the people in charge to enhance environmental awareness, consciousness of serving the overall situation, to ensure that the main responsibility to put in place; the third is Duocuobingju full supervision of the remediation coal-fired boilers demolition work to ensure full demolition tasks to complete the rectification of high-quality, on-site in time for the use of special equipment write-off procedures to monitor and update the information platform, the rectification work will not stay dead; fourth is to strengthen the rectification pin number system and standardize accounting, according to " Qinghai province to implement the central requirements of environmental protection inspectors feedback pin number rectification work approach ", the timely development of ledger collect relevant information, to ensure that the sales numbers for the record rectification work tasks.

Up to now, the central feedback requirements Haidong included the removal of 35 planned coal-fired boilers have been demolished 24 units, of which the county mutual aid, Ledu District, safe area, Minhe County, Hualong County coal-fired boiler demolition has been completed work to complete the renovation work ahead of coal-fired boilers. Next, Haidong will continue to increase coal-fired boilers eliminated, remediation publicity work to do mass persuasion to explain, guide active community participation, active support and cooperation to carry out "ban on burning 'governance activities. Actively persuade pressure coal-fired boiler units to implement the "coal to oil", "coal to gas", phasing out coal-fired boilers high pollution, high energy consumption, encourage economic boiler unit to switch to environmentally friendly, safe and efficient biomass, natural gas, etc. clean energy.
