Abstract

PURPOSE:To evenly perform an average refuse charge to contrive the lowering of the fluctuation of calculated lower heating value by performing the information for calculating an average refuse charge by the average of movement whenever each refuse charge time interval is divided into many unit times and the unit time elapses. CONSTITUTION:In a hoper 4, pieces W2,... Wn, Wn+1,... of refuse 2 are successively charged at the times t2,... tn, tn+1,.... The average movement value of an average refuse charge M (kg/hr) per unit time at the average movement time K (hr) previously set in a constant range is calculated whenever the unit time elapses. First average refuse charge M (tn) is expressed as M(tn)=W1+W2+ Wn/K. The heating value of a furnace 1 is calculated from the heat balance of the furnace 1 as soon as the average refuse charge M is calculated to make them H(tn). The lower heating value Q(tn)=H(tn)/M(tn) is calculated by dividing the heating value H(tn) by the average refuse charge M(tn) corresponding thereto. The fluctuation of the calculated lower heating value Q is very small.

The most appropriate method for the amount of garbage burned f in the above equation is to use the rate at which garbage is removed into the furnace by the butcher (a/hr), but since it is not always easy to measure it, conventional In the calculation method, the average amount of garbage inputted into the hopper per unit time m (o/hr) is used instead. However, since the amount of garbage input has large temporal fluctuations, the average amount of garbage input m is determined by a preset moving average time k (
hr) is adopted. The moving average time is the time range when performing the moving average.
It is usually set to 2 to 3 hours. To explain this conventional calculation method in more detail using the graph in FIG. It is assumed that the conditions are filled and filled. As the furnace is operated, the amount of garbage in the hopper decreases, and at time t1 when it reaches a few limits, the hopper is filled with garbage W1 again.

Problems to be Solved by the Invention However, in the conventional calculation method described above, since the amount of garbage input W at each time is a discrete value of about one piece every 5 to 20 minutes, a moving average value is used as the average garbage input Jim. Even if it is adopted, there is a problem that the fluctuation is large, and as a result, the calculated lower heat generation 1q also fluctuates greatly.

Effects According to the configuration of the present invention described above, the period between each garbage input time (t) is divided into a large number of unit times (u), and the garbage input is performed at the average garbage removal speed (V) for each unit time (u). Based on this average garbage removal speed (V), calculate the moving average value of the average garbage input amount (M) per unit time in the moving average time (K) every unit time (u). Since it is calculated, the average amount of garbage input (M) is extremely smoothed. Therefore, the variation in the lower calorific value (Q) calculated by dividing the generated heat value (H) by the average amount of garbage input (M) is extremely small.

(W) is divided by the time between both garbage input times (t) to calculate each average garbage removal speed (V), and between the two garbage input times (t), each unit time (u) is calculated. It is assumed that garbage is inputted at the respective average garbage removal speeds (V), and these average garbage removal speeds (V
), the moving average value of the average amount of garbage input per unit time (M) within a certain range of moving average time (K) is calculated every unit time (u), and at the same time, the A waste incinerator lower heat value is characterized in that the generated heat value (H) is calculated from the income and expenditure, and the lower calorific value (Q) is calculated by dividing this generated heat value (H) by the above-mentioned average waste input amount (M). Quantity calculation method.
