The South African steel industry is very developed, but in the steel industry production process, a large amount of high-temperature flue gas is emitted. These flue gases carry a lot of heat energy, and if they can be used effectively, they will produce high economic benefits. The waste heat boiler produced by ZG boiler is mainly used for recycling high-temperature flue gas from industries such as chemical industry and steel. It is used for central heating or power generation. It is a kind of equipment that develops circular economy and saves energy.

Since 2017, located in Changchun City, Jilin Province to accelerate the governance of coal-fired boilers within the city out of small coal-fired boilers remediation process. Up to now, the work has achieved initial success.
15 in the city with 20 kilowatts and above the coal-fired generating units, 13 units have ultra-low emissions; city table 292 with 20 t steam / hour or more coal-fired boilers, emission standards have reached the count 253 male , accounting for 86.64% of the proportion of the boiler with; the city built area of 10 steam tons / hour small coal-fired boilers 2962 units, out of a total of 29553 units, up 99.7% out of proportion, the basic completion of the national requirements out of the task.
In order to further improve air quality, improve people's living environment standards index, Changchun City by expanding the ban on burning area, improve the standard phase-out of coal-fired boilers, plans to use two years of urban 20 tons of steam / h coal-fired boiler (kiln) furnace eliminated.
By the end of 2017, the city has eliminated 20 tons of steam / hour coal-fired boilers 964 units; at the same time to speed up the central heating and (expanding) network as well as the pace of clean energy promotion, provide for the transformation of the city's coal-fired boiler control a strong guarantee.
In recent years, Changchun City, adhere to the full implementation of coal-fired boilers governance, to improve ambient air quality in Changchun City has played a positive role. 2017, good days Changchun 276 days, compared with 2013, an increase of 35 days; heavy pollution days 10 days compared to 2013, reduced by 33 days; major air pollutants respirable particulate matter (PM10) and fine particles (of PM2.5) were 78 mg / m and 46 micrograms / cubic meter, respectively, 39.5% and 37.0% decrease over 2013.
