Interpretation of the best configuration of domestic waste incinerator and waste heat pan

Release time:2017-03-09Author:admin

As we all know, agricultural living garbage incinerator is a very important component of the grate, China's waste incinerator grate is mostly imported, and waste heat boiler domestic design and manufacturing are more mature. The current situation is usually the practice of using imported grate and domestic waste heat boiler matching. So the choice of waste calorific value design point selection and waste heat boiler design is a more sensitive issue. How to make the best configuration of waste incinerator and waste heat boiler is a key problem in the design department. The raw material of waste incineration power plant is municipal solid waste, the calorific value of urban life is usually in the range of 1000-1500kcal / kg, rather than the fuel power plant in the design, only consider where the use of fuel coal, there is a relative Fixed fuel coal supply point, so the design value of the calorific value in the design of coal- fired power plants is relatively stable. Waste incineration power plant in the design, in order to better note the incinerator and waste heat boiler supporting the problem, but also take into account the value of household waste with the improvement of living standards change, so the garbage power plant in the design to consider garbage Value can not be too low to consider the garbage calorific value design can not be too high design value, so there is the MRC design calorific value of the problem.

Design units are usually based on experience to estimate the next five years the local people's living standards to develop the garbage value as a design point to design. If the design point selection is unreasonable, this will cause the incinerator and waste heat boiler is not exactly match. Such as garbage design value is too high, when dealing with China's low calorific value of domestic garbage, in order to ensure that the waste heat boiler to achieve the design capacity (output), is bound to increase the amount of waste or add other auxiliary fuel to ensure that the furnace temperature 850 ℃ above and can ensure that the flue gas residence time of 2 seconds or more, can achieve the waste incinerator and waste heat boiler better matching effect and national environmental emission requirements, is bound to cause long-term overload operation of waste incinerator, and waste heat boiler capacity To achieve the design capacity, so that the garbage incinerator is very unfavorable. If the waste calorific value design point is too low, in order to ensure that the waste heat boiler to achieve the design capacity to ensure that the furnace temperature above 850 ℃ and to ensure that the flue gas residence time of 2 seconds or more, the incinerator is bound to cause waste reduction, The furnace is running at a low load for a long time, wasting the capacity of the incinerator.

As an experienced incinerator and waste heat boiler designers, it is common practice to estimate the amount of waste calories (assuming calorific value) as a MRC design point after ten years of local household waste. This can take care to the garbage incinerator and waste heat boiler configuration problems, get a better deal.
