SU79490A1 - Grinderless chamber for burning milled peat - Google Patents

Description

The object of the present invention is a grinder-free furnace intended for burning milled peat.

The furnace is equipped with a vertical dryer pipe, the upper part of which is connected to the combustion chamber by means of an expanding nozzle, which is a burner. The heated air is introduced through a slot located at the bottom of the pipe. A cylindrical separation bag is provided at the bottom of the dryer tube, which serves to trap and remove impurities in the fuel.

The schematic drawing shows a mill-free chamber furnace for burning milled peat.

The furnace consists of a pipe-squirly 7 with a separating bag 8 and a combustion chamber 9 with a cold funnel 13.

The work of the furnace is as follows:

chute 6 directly to the pipe dryer 7.

The dryer pipe is a round pipe, the upper part of which is connected to the combustion chamber with an expanding nozzle.

The fuel that has entered the dryer pipe 7 is picked up by a stream of hot air supplied from below through the annular slot 10, which is located at an angle to the axis of the pipe.

The speed of hot air at the beginning of the pipe should be 25 m / s, which ensures that all particles with a size of up to 15-20 mm are picked up. When transporting peat through a pipe, it is very intensive to dry it in a suspended state.

Separate larger pieces of peat budzt repeatedly fall down and again rise with a jet stream. When hitting the upper PLATE}, the peat pieces will undergo some grinding, which will contribute to the combustion of the firebox. Metal pieces and occasional large pieces of peat fall into the separation bag 5 and are automatically removed through flashing lights. Dried and well mixed with
