Abstract

The utility model discloses an internal combustion engine taking pulverized fuel as fuel. An inlet duct is arranged in front of the internal combustion engine. A low-pressure compressor and a low-pressure turbine are connected to the same shaft; a high-pressure compressor is arranged between the low-pressure compressor and the low-pressure turbine. A firebox and a high-pressure turbine are arranged on the same shaft; the high-pressure compressor and the high-pressure turbine are connected to the same shaft, and the firebox is arranged between the high-pressure compressor and the high-pressure turbine. An off-gas tube is arranged on the afterbody of the internal combustion engine. A tank is communicated with an oil pump through an oil pipe. The oil pump is communicated with the firebox through an oil pipe. A pulverized fuel box is communicated with a pulverized fuel feeder through a pulverized feeding pipe. The pulverized fuel feeder is communicated with a burner through a pulverized fuel feeding pipe. The burner is arranged in the firebox, or between the high-pressure compressor and the firebox. By adopting the internal combustion engine taking pulverized fuel as the fuel, pulverized fuel, much of which is reserved, is used as the fuel, and the problem that power is supplied through the high temperature produced by burning of pulverized fuel is solved; and power is given directly through high-temperature and high-pressure gasses produced from burning of pulverized fuel.

Description

Dust internal-combustion engine

Affiliated technical field:

The utility model relates to a kind of dust internal-combustion engine, belongs to the engine manufacturing technology field.

Background technique:

Need a large amount of fuel during the internal-combustion engine acting, and existing internal-combustion engine all adopts the internal-combustion engine of fuel such as kerosene, gasoline, diesel oil and inflammable gas, dust of no use (comprising coal dust, coal dust, ignitable dust) is the internal-combustion engine of fuel, up to the present just do work with dust high temperature of generation when the burning, the high pressure that produces during dust combustion of no use does work.

The model utility content:

The utility model is at the problems referred to above: it is fuel used to change traditional combustion engine, use the many dust of reserves to make fuel, solved the problem that the high temperature that only produces by dust combustion comes work done, realized that dust combustion produces the direct work done of high-temperature high-pressure fuel gas, if the dust internal combustion engine is installed on the boiler, water channel is connected together, and more the High Temperature High Pressure of good utilisation dust combustion generation is done work simultaneously, reaches energy-conservation purpose.

The technical solution of the utility model is finished as follows: intake duct is in the internal-combustion engine front, low pressure compressor and low-pressure turbine are connected on the same axis, high-pressure compressor is housed between the two, firing chamber and high-pressure turbine, high-pressure compressor and pressure kettle wheel are connected on the same axis, combuster between the two, offgas duct is installed in the internal-combustion engine afterbody, fuel tank is communicated with oil pump through oil pipe, oil pump is communicated with the firing chamber through oil pipe, dust box is communicated with machine supplying powder through giving tube cell, and the machine supplying powder warp is communicated with burner to tube cell, burner be installed in the firing chamber or be installed in high-pressure compressor and the firing chamber in the middle of.Described dust internal-combustion engine is an internal-combustion engine of making (comprising coal dust, coal dust, ignitable dust) fuel with dust.

It is fuel combustion that the utility model adopts with the dust; Air enters the firing chamber after intake duct continuously is inhaled into low pressure compressor and high-pressure compressor compression supercharging, right oil is under the effect of oil pump, entering combustion chambers burn from fuel tank through oil pump becomes the right gas of High Temperature High Pressure and enters the turbine acting of expanding, when chamber temperature reaches the optimum temperature that dust combustion uses, dust is under doing of machine supplying powder used, from dust box, machine supplying powder enters combustion chambers burn through burner becomes the right gas of High Temperature High Pressure, entering the acting of expanding in the turbine again.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described in further detail:
