Renovation is done to the boilers system for saving of energy and water and near zero discharge of wastewater. Some sufficient conditions to guarantee the boilers are safe and economic operation in the zero - emission conditions. So it could reduce energy and water consumption,pollution emission,production cost,and enhance enterprise competitiveness. The boilers system is featured by safety,energy saving,water saving and emission reduction. The practice shows that the boiler supply water quantity of per ton of steam has decreased from 1. 5m3 to 0. 073m3 ,the waste water discharge of per ton of steam from 1. 4m3 to 0. 003m3 ,the coal consumption of a ton of steam from 168. 3kg to 152. 3kg,the dissolved solids of boiler water from 3000mg/ L to 2100mg/ L,and the corrosion rate of carbon steel is less than or equal to 0. 001mm/ a,the scale inhibition rate is greater than or equal to 99. 95% . The 2 sets of 35t/ h medium - pressure boilers will save cost of 8. 253million yuan an annual.
