Measuring the Heating value of municipal solid waste mixed with the output waste from processing facilities and comparing the results with Tanner triangle for assessment of combustibility of Waste (A case study on the garbage of Qazvin)

In 1393, the daily average of waste produced in Qazvin was 300 tons that Per capita waste generation is 680 grams per person per day. To control these wastes, methods including composting, landfill and waste-to-energy conversion should be applied. The most common method of converting waste to energy incineration is done in the power plant. According to the World Bank, to build a waste incineration plant for burning waste without using additional fuel. The calorific value must be at least 7 Mj/kg and not less than 6 Mj/kg .Also the weekly fluctuations should be less than 20%.
In this study the samples of mixed wastes were taken to determine the quantitative and qualitative characteristics of the mixed wastes for one year. The samples were collected during one year. (Saturday, Monday and Thursday of each week) each time 5 samples were taken. To determine the characteristics of the output waste from processing facilities. Analysis of moisture, combustible materials and ash content, heating value were done according to standard criteria.
The results showed that the calorific value of Urban mixed waste of Qazvin is 6.133 Mj / Kg. The percentage of moisture was 50.3%, the ash 30.1% and the combustible materials 27. 9% .The calorific value wastes output of processing facilities was 11.8 Mj / Kg.
The waste output of processing facilities is more adaptable with Tanner pattern. Due to the high calorific value wastes output from processing facilities and its low moisture content. The Refuse derived fuel facility should be applied for waste management in Qazvin.
