For winning the Battle of Blue Sky, Jiuquan City, Gansu Province, issued in 2019 action to implement the program, which requires: accelerate the implementation of the transformation of ultra-low emission thermal power and other key industries. Details are as follows.

First, in an orderly clean heating in winter

Seriously implement the "clean Gansu winter heating overall plan (2017-2021 years)" and "clean Jiuquan City winter heating embodiment (2017-2021 years)", combined with the overall urban planning and development of real priority to the development of central heating and accelerating focus heating pipe network construction and transformation progress, and constantly improve the urban central heating cover, reduce civil bulk coal usage, central heating difficult coverage areas, speed up the implementation of all types of decentralized clean heating.

Second, the full completion of the comprehensive improvement of coal-fired boilers

And by phasing out the demolition, clean energy transformation, environmental compliance management, etc., complete with coal-fired boiler remediation tasks. Increase efforts to eliminate small coal-fired boilers, the county level and above urban area (high-tech zones, except through the open area, industrial parks and industrial agglomeration area) basically eliminated 10 tons of steam per hour and coal-fired boilers and furnaces tea, operational stove, grain storage and drying equipment, coal-fired facilities, in principle, to 35 tons of steam per hour, the new coal-fired boilers, in principle, to the rest of 10 tons of steam per hour, a new coal-fired boilers.

Third, strengthening the total control and the clean use of coal

Issued according to the provincial total coal consumption control objectives and annual coal consumption indicators, strengthen coal total control. New coal coal project implementation reduction alternative, reduce the proportion of coal in energy consumption, improve power coal in total coal consumption in proportion.

Fourth, accelerate the development of clean energy and new energy

Gradually increase the proportion of non-fossil energy consumption, the orderly development of hydropower, optimizing wind, solar energy development layout, coupled encourage the promotion of coal-fired biomass power generation, local conditions to develop biomass energy, geothermal energy, to ensure that by 2020, the city's non-fossil fuels in energy the proportion of total consumption reached 20%. Increase renewable energy consumptive efforts to solve the basic water abandoned, abandoned wind, abandoned light problem.

Boiler gas supply system generally supply duct inlet means, gas piping system and a boiler room emission purging conduit and other components. Some requirements are as follows:

1) from the boiler room to the gas pressure regulating stations gas pipeline (gas introduction tube boiler), except when special requirements need to consider the production of the outer gas tube double, generally single gas pipe. When gas double pipe, each pipe capacity by gas boiler 70% of the total gas consumption is calculated.

2) When the intake pressure regulating device in more than 0. 3MPa, and larger than the surge, large noise may be generated, in order to avoid the noise transmitted along the duct to the rear gas boiler room, the regulator means 10 to suitable 15m section of pipeline laid underground to take.

3) gas is introduced from the outside manifold gas boiler room, the total should be installed at the inlet shut-off valve, a gas-flow direction, the valve should be installed before the vent pipe, and a sampling port mounted in the vent pipe should be installed after the purge valve joints.

Why is the boiler discharging?

The purpose of boiler blowdown:

Henan fast boiler novel Free supervisory inspection 5 tph biofired steam boiler and Characteristics of the fast boiler steam boiler is a gas integrated small steam boilers, the use of forced circulation DC coil structure, with safety, high thermal efficiency, steam generation, high degree of automation specialty. 1, in accordance with safe "Steam Boiler Safety Technology Supervision" provisions, the boiler water capacity of less than 30L boiler does not belong to the range of coverage, without inspection and approval. 2, high thermal efficiency thanks to the principle of countercurrent heat exchanger, steam boiler exhaust gas temperature of less than about 110 deg.] C, operating thermal efficiency of 92%. 5-10% higher than conventional steam boiler. Henan fast boiler steam boiler imported from Germany frequency premixed combustion apparatus, the unique design of the burner and the combustion air is premixed gas, into the interior of a boiler and a high-speed rotation of the spherical combustion flame is formed, so that complete combustion of all the fuel, the maximum amount of heat transmitted to the coil, in order to maintain low oxygen content in the flue gas, the excess air coefficient is much lower than the national standard. 3, the steam generation capacity of the steam boiler fast due to water is extremely small, heating temperature after 3 to 5 minutes to produce steam, and generally conventional boiler takes more than 20 minutes, significantly reducing the warm-up time, save energy and improve the speed of the reaction system . 4, a high degree of automation Henan fast boiler is a steam boiler water to generate the steam to the steam generating device monolithically integrated, from the replenishment water - steam supply all the equipment in the factory integration is completed, the entire linkage control system, PLC control system can in accordance with external load size automatic adjustment system operation fault alarm, truly automated unattended operation.
