The essay serve a documented basis for joint project of erection and operation of biomass residue firing CHP (Combined Heat and Power) unit. 58 tons/hour of steam at 12 barg are generated in few heavy oil firing boiler thermal boilers and consumed in production process. The basic assumptions are that saw dust or/and wooden chips with LHV (Low Heating Value) 18,000 kJ/kg will be fired in a fluidized bed boiler producing about 30 ton/hour steam (about a half of needed process steam). The steam flow, passing through a back pressure turbine, will generate electricity corresponding to difference of enthalpies of fresh steam generated in the boiler and of one needed for process. From the turbine outlet the steam will be used, as today, for the technological process of the factory.

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.

Wns series oil and gas boiler thermal boiler

This kind of boiler is an oil and gas fire tube boiler produced by ZBG, which is a small capacity boiler. The use of large-area combustor design, advanced corrugated furnace structure, threaded pipe design and other technologies to improve boiler thermal efficiency.

With zg's overseas layout, zg once again cooperated with foreign companies. zg provided a 45 ton biomass boiler thermal boiler to a palm oil plant in Puntarenas Province, Costa Rica.Costa Rica is a beautiful country. Although it is still an agricultural country, it has achieved a relatively high standard of living and tourism is booming.
