vertical tubeless boiler for school

In Apr 2014, there was a set 75 ton biomass fired steam vertical tubeless boiler for school to Manila, Philippines, and until now, the boiler is working well in power station.

Recently, Nanchang, Jiangxi Province to fully implement the national environmental protection work conference and the province's environmental protection work conference, combined with the actual situation of the city, issued a "blue sky Nanchang win the Battle of three-year action plan (2018-2020 years)" (referred to as " plan"). "Plan" put forward a management plan for major air pollution problems.

As the relevant departments to actively promote the utilization of clean energy. The city gradually reduce the proportion of coal consumption, by 2020, coal accounted for the proportion of energy consumption dropped to below 65%; principles and has gradually increased the proportion of natural gas energy consumption, adhere to "the electric power should", "should air the gas" to promote natural gas work to build the pipeline, steadily "coal to gas" project.

2018, the main city of Nanchang to the new area, the main city area and open small blue through the open area to expand the range of city ban on burning areas. By the end of 2020, Nanchang County, Jinxian, Anyi required scoping combustion zone ban within the jurisdiction of, and informed consent of the uniform implementation of the municipal government.

"Plan" put forward in 2018, the main city of the new areas into the combustion zone ban, the main city through the open area and a small blue through the open area phasing out the 10 steam tons / hour and coal-fired boilers; 35 tons of steam launch built-up area / out of hours and coal-fired boilers. As of 2020, the city built basically out of the region 10 steam tons / hour and coal-fired boilers, coal-fired boilers within 10-35 tons of steam / hour range is substantially complete alternative clean energy sources, and no longer approve new 10-35 steam tons / hour of coal-fired boilers.

Specific the following two cases.

1, the same tonnage boiler

Condensing heat recovery vertical tubeless boiler for school comprises a latent heat of vaporization and sensible heat of the water vapor portion of the high temperature flue gas. Recovering sensible heat change with decreasing flue gas temperature is not great; recovered latent heat of vaporization of water vapor as the temperature decrease vary greatly, when the higher exhaust gas temperature, very little recovery of latent heat, with significantly lower exhaust gas temperature, the recovery of latent heat increases rapidly, and subsequently stabilized, condensed from the point of view, the difficulty of flue gas condensation of the flue gas with decreasing temperature and increasing.
