4. Suspension structure is good for absorbing boiler expansion and makes it safe in operation.

5. Closed ash discharging device makes it achieve flue gas side seal box automatic slag discharge.

What is packaged boiler: packaged boiler is assembled for boilers and boiler relative to the bulk, packaged boiler manufacturer refers to the above basic installation work has been basically completed in their own units, after inspection and acceptance transported to the installation site, hoisting the boiler to the base, and then after acceptance by checking, installed pipes and other rotating machinery (blower, fan), and a dust environmental protection facilities, may be test run. General production unit boiler body stock, so short installation period. Prefer quick oven such as gas-fired boiler WNS quick product, efficiency and thermal efficiency are high, and the small footprint, long life, cost is not high, the general is a small stove or emergencies when urgent.

The size of the boiler pressure about the size of the load, is adjusted by adjusting the pressure regulator to achieve. When adjusting the load, simultaneously adjusting air pressure, air volume control must be synchronized, to ensure proper gas to match the air flow, so as to achieve economic operation of the boiler. In normal operation, the gas may not be a sharp turn up or down, in order to avoid abrupt change in combustion, the pressure receiving member suddenly damaged dilations.

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.
