【発明の詳細な説明】 〔産業上の利用分野〕 本発明は都市ゴミの焼却方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for incinerating municipal waste.

焼用空気供給量の調節を行っていた。In conventional incineration methods, the amount of municipal waste fed into the incinerator at each input port and the number of inputs per unit time are measured.
Based on the measurement results, the amount of municipal waste supplied to the incinerator is adjusted to suppress fluctuations in the supply weight per unit time, and the combustion exhaust gas from the incinerator is measured. Based on the results, the amount of combustion air supplied to the incinerator was adjusted to ensure complete combustion.

欠点があった。[Problem to be solved by the invention] However, in the conventional incineration method, many measurements are required, such as measuring the feed weight for each input port, measuring the number of inputs per unit time, and also measuring the combustion exhaust gas. This method has the disadvantage that it requires a lot of effort for measurement.
本発明の目的は、測定に関する手数を少くして、都市ゴ

ることにあり２．その作用・効果は、次の通りである。The characteristic means of the method of incinerating municipal waste in the present invention is to measure the apparent specific gravity of municipal waste, and based on the measurement result, calculate the supply capacity of municipal waste to the incinerator per unit time according to the apparent specific gravity. The larger the apparent specific gravity, the smaller the amount to suppress fluctuations in the amount M of municipal waste supplied per unit time, and the amount of combustion air supplied to the incinerator is set to be smaller as the apparent specific gravity becomes larger. 2. The aim is to suppress fluctuations in excess air ratio. Its actions and effects are as follows.

できる。In other words, as the water content (V) increases, the apparent specific gravity of municipal garbage increases, and the weight per Φ aspect increases, which reduces the supply capacity to the incinerator per unit time. By doing so, fluctuations in the weight of municipal waste supplied per unit time can be suppressed, and the apparent specific gravity increases. Since the calorie per liter is low, by reducing the amount of combustion air supplied to the incinerator, fluctuations in the excess air ratio for complete combustion can be controlled.

In order to completely burn and incinerate a predetermined amount of municipal waste in a short operation time of -1 day, the municipal waste processing equipment that consists of the following methods measures the apparent specific gravity of the municipal waste, and based on the measurement results, If we reduce the supply capacity of municipal waste to the incinerator (2) per unit time as the apparent specific gravity increases to suppress fluctuations in the weight of municipal waste supplied per unit time, then
The amount of combustion air supplied to the incinerator (2) is set to decrease as the apparent specific gravity increases, thereby suppressing fluctuations in the excess air ratio.

となる。In other words, the incinerator (2)
A hopper (5) for receiving the workpieces from the pinto (1) which are intermittently supplied by the transport crane (4) according to 1) and supplying the workpieces in this hopper (5) into the furnace. The butcher type feeding device (6) is attached to the furnace body (7).
A stoker (9) is connected to the supply port (8) of the material to be processed (8) of the furnace body (7) and conveys the material to be processed that has been supplied in a stagnant state near the supply port (8). An ignition burner (10) facing the supply port (8) in the L space of the stoker (9) is provided on the furnace wall on the opposite side from the supply port (8) No. 111, and the combustion gas is In the space, there is a supply port (8
) to drying zone (A), combustion zone (B) and after-burning zone (C)
The stoker (9) is formed so as to be combusted while being dried by the combustion air supplied from the forced air blower (12).
An ash chute (15) is installed to catch the incinerated ash flowing down the gap between the cranes (4) and 1. (11) Municipal garbage itj: A meter to measure I■
In addition to installing a device (13), a high level sensor (IIs) is installed at the -L part of the hopper (5), and a low level sensor (1, s) is installed at the bottom of the hopper (5). When the top surface of the garbage reaches the position (L) of the low level sensor (LS), the crane (4) transports the city garbage one level from the bit (1) to the height of the low level sensor (H5). (11) until the amount of garbage is reached, and the number of times of input at this time is
Measure the weight of municipal garbage for each amount of input, and let the total input weight at that time be B (t), and the volume from the low position (L) to the high position (11) in the hopper (5) as A (nf). Since municipal waste is constantly being fed into the furnace by the feeding device (6) while it is being fed from the low position (1,) to the high position (1) by the crane (4), the feeding time in between is 1. '
(h) and the amount of garbage supplied per unit time by the supply device (6) is C (cm/t+), then the apparent specific gravity of municipal garbage is A+CT.

。Then, based on the measurement results of the apparent specific gravity, the quality of the trash is ranked into three types: high quality, standard quality, and low quality according to its calorific value. In detail, depending on the region, the quality of garbage follows the almost straight line -L in Figure 2, and those with an apparent specific gravity of 0.2 to 0.3 have a low water content and a calorific value of approximately 2000 to 3000 Kcal.
Garbage with an apparent specific gravity of 0.3 to 0.35 is classified as high quality with a calorific value of 1,200 to 2,000 kcal/Kg, and garbage with an apparent specific gravity of 0.35 or more has a high water content and calorific value. is classified as low quality with approximately 700 to 1200 Kcal/Kg.

t/day), high-quality waste is in the first pattern (a),
Standard quality trash is in the second pattern (b), and low quality trash is in the third pattern.
In order to change in accordance with pattern (c), the garbage supply capacity per unit time of the supply device (6) is changed according to the pattern according to the quality of the dust, and at the same time, the feeding speed of the stoker (9) is also changed according to the pattern (c). Adjust in proportion to 6).
