Recently, the energy-saving retrofitting project for the purely-fired blast furnace gas of No. 1 boiler of thermal power plant reported by Zhongtian Iron & Steel Group in October last year has now been awarded the "Changzhou City Staff Top Ten Rationalization Proposal Award" and has received a bonus of 3,000 yuan.
With the continuous expansion of the Group's scale, blast furnace gas has also increased significantly. The existing gas consumption system of the Group is not enough to consume this part of blast furnace gas. If excess blast furnace gas is dispersed, it will waste energy and pollute the environment. To this end, the thermal power plant started to implement the comprehensive utilization of surplus blast furnace gas, and changed the existing 1# pulverized coal boiler from coal to pure blast furnace gas, making full use of surplus blast furnace gas as fuel for boilers to produce steam.
Immediately after the proposal was put forward, it was highly valued by the group. The project started on August 15, 2014 and was commissioned after commissioning in November of that year. According to the data tracking, after the implementation of the energy-saving reform project for the purely-fired blast furnace gas of No. 1 boiler of thermal power plant, from December 1, 2014 to September 30, 2015, the cumulative gas consumption of 102.759 million cubic meters of blast furnace gas will be saved, saving 15,7357.4 tons of coal. Calculated during the average coal price of 430 yuan / ton, to obtain direct economic benefits of 6766.3682 million yuan, 1596.46 tons of sulfur dioxide emissions, 259,600 tons of carbon dioxide, and obtained good economic and environmental protection effects.
Since the benefits of the energy-saving reform of the purely-fired blast furnace gas of No. 1 boiler in thermal power plant are obvious, the plant also carried out the energy-saving reform of pure blast furnace gas for No. 3 boiler last year. At present, the plant can consume 880,000 cubic meters of blast furnace gas per hour and can basically consume the Group's surplus blast furnace gas.
Hammer Breaker Chisels
Hydraulic breaker hammer chisel tool wearing resistance with longer working life
While we asked our loyal user why you always choose our hydraulic breaker hammer chisel tool. The user told they also bought from Korean years ago. hydraulic breaker hammer chisel tool quality is very good quality. And hydraulic breaker hammer chisel tool is three times longer working life than normal brand. The most important the chisels have nothing failure at all in these years.
Hydraulic breaker hammer chisel tool features:
1.Good quality material
Many kinds of steel can be made to hydraulic breaker hammer chisel tool. But different material means different quality. We choose the most competitive but very good material HB as the standard material. This materail is higher strength, good toughness,and it can stand continue impacting.
Different heattreatment
Except the raw material, heattratment is another fatal point to a good quality hydraulic breaker hammer chisel tool. We use salt-bath furnace in house with longer time to make use the material is penetration for longer working life.
