thermax sgi 005 steam boilers

On the "low nitrogen" process, the use of international tip side quickly premix, the FGE other combustion flue gas recirculation techniques, starting from the different positions of the boiler, the nitrogen oxide emissions fall again, less than has been achieved 18 mg / cubic meter remarkable results.

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.

Simple once-through boiler configuration, there is no bulky drum, the downcomer may be used or less, but the evaporator heating surface within which the working fluid flows discharged power can provide natural circulation, the pump needs to be borne by all.

(2) Reasonably carry out boiler blowdown. Boiler sewage is divided into regular sewage discharge and continuous sewage discharge. Regular sewage discharge can eliminate water slag and sediment in the boiler water. Continuous sewage can reduce the salt content and silicon content of the pot water. Therefore, the boiler duty officer should strictly implement the technical measures specified in the technical standards and the operational sub-fields when carrying out the sewage discharge work.
