Recently, the Government Office of Hebei Province issued the "Hebei province coal investment projects coal alternative management approach", mainly to strengthen air pollution control, the implementation of total coal consumption control target. The new "management approach" referred to new construction, renovation, expansion project of coal, coal should carry out the same amount of reduction or substitution (hereinafter referred to as a substitute for coal). Coal substitute coal should be completed before the project goes into operation.

These measures apply to administrative areas in Hebei coal for direct consumption of fixed asset investment projects. It refers to the direct consumption of coal raw coal, washed coal, other coal washing, coal slurry, coal, coal and other raw materials or fuels production and processing or combustion, its coal facilities (facilities, tools) including boilers, furnaces , gasification, blast furnace and so on.

Coal alternative pathway includes the following four aspects: the elimination of backward production capacity, excess capacity and Yajian enterprises closed down, converting reduce coal consumption; the implementation of central heating, reduce coal consumption saving technological transformation or removal of equipment out of coal-fired boilers and other equipment coal consumption; use of renewable energy, natural gas, electricity and other clean energy alternative to coal consumption; the other to meet the requirements of coal consumption reduction approach. Replacement of coal coal project supervision and management, energy conservation authorities responsible for co-ordination at all levels.

Condensing boiler heat exchanger fouling problems: As a new condensing boiler gas boiler, gas and water quality of a higher demand, if the purity is not enough gas, the burner can easily lead to pore plugging, whereas if the boiler water hardness is too high, it is easy to produce large scale, affecting the normal heat, thereby reducing the thermal efficiency of the boiler, a little serious, it also reduces the life of the boiler. Auxiliary heat exchanger is an important need for a condensing boiler, a good heat exchanger can be quickly transferred to the water, and then delivered to the end user. And if the case of heat exchanger fouling occurs, it will affect the results of the heat exchanger, or even a local high temperature, there is the risk of burst pipes or even boiler explosion. Boiler heat exchanger fouling is a very complex issue. From practical experience, the formation of fouling is substantially as follows: ① induction; ② soil particles to the heat transfer surface of the migration process; ③ soil particles in the heat transfer surfaces of the adsorption process; ④ fouling deposit hardening process; soil release ⑤ process. However, theoretically, in the formation of dirt while also accompanied by falling dirt.

ZG Boiler constantly driving towards new improvements in combustion technology of 10MW utility boiler and in material applications which allow our products to burn a wide range of fuels cleanly while meeting the most stringent environmental regulations on nitrogen, sulphur oxides, particulates and greenhouse gas emissions.

"Module", equivalent to a single large boiler split into several small boilers, in the number of "simple parallel combination" may be implemented in different tons of steam demand. Modular design structure determines the three characteristics of the boiler. 1, each boiler backup each other upon a single fault occurs in the boiler, the boiler can start immediately the other, a very small effect on the heating. 2, capacity scalability is good, a lot of demand for heating office buildings and other heat load life will change in different seasons, the selection module boiler can be the perfect solution to this situation, at any time by increasing or decreasing the number of boiler units, achieved a smaller investment meet the demand. 3, boiler room infrastructure do not ask, can significantly reduce capital investment costs.
