In Harbin fifth session of the Fourth Session of the National People's Congress, coal-fired united states bagasse fired boiler manufacturers governance as a key task to be mentioned again. Meeting specific targets: by 2019, Harbin will govern coal-fired boilers, boiler out of 35 tons and below do not have to upgrade conditions, starting 65 tons or more of coal-fired boilers and energy-saving ultra-low emissions transformation.

2019, Harbin will continue to strictly control the total amount and quality of coal, according to local conditions to solve the shanty towns, suburban town (township) village coal powder burning problem by briquetting, Burying to field, the way raw material cogeneration, effective path to explore the comprehensive utilization of straw, the straw open-air Jinshao continue to focus on the work to implement the required emission limits industrial emissions, car exhaust strengthen, kitchen fumes, dust and other site management, effectively improve air quality.

2018, Harbin City, air pollution, elimination of coal-fired boilers 1191 units, biomass boilers to replace more than 10,000 units, updated bi-fuel taxi 1270 units, 1323 units of new energy buses, comprehensive utilization of straw and prohibiting open-air work strength forward, ambient air quality fine days up to 312 days, an increase of 42 days over the previous year, the highest level since the ultra-high PM2.5 monitoring.

2) Low polluting

NOx and SOx emissions are significantly decreased without special environmental modifications. In the case of fluidized-bed boilers, desulfurization is carried out intrafurnace,using mainly limestone as the fluidizing material.For denitration,PC boilers operate at combustion temperatures from 1,400oC to 1,500oC,whereas circulating fluidized-bed boilers operate at lower temperatures, ranging from 850oC to 900oC, thereby suppressing thermal NOx emissions as the generation of NOx is dependent upon the combustion temperature. In addition, the operation of

Second, the shutdown maintenance and corrosion

1. boiler after shutdown, in order to prevent corrosion of the pot must be maintained.

2. Short-term maintenance. Wet regimen employed; i.e. after the shutdown, the water will fill the furnace, the entire exhaust air.

There are many successful cooperation cases, In 2012, there was a energy saving
