Coal-fired powder internal-combustion engines and generator capable of regulating and controlling generated energy

Abstract

The invention relates to coal-fired powder internal-combustion engines. Each engine comprises crankshaft, at least one cylinder body and a piston arranged in each cylinder body, wherein each piston is connected with the crankshaft through a crankshaft connecting rod; the lower part of each cylinder body is connected with an inlet of an air coal powder input pipe, and a feed valve is connected to the air coal powder input pipe in series; the bottom of each cylinder body is connected with an outlet of exhaust gas coal ash eliminating pipe, and a blow-off valve is connected to the exhaust gas coal ash eliminating pipe in series; an ignition device is arranged at the lower part of each cylinder body; an ultrasonic launcher capable of launching ultrasonic waves towards each cylinder body is arranged on each piston or at the bottom of each cylinder body. A generator capable of regulating and controlling generated energy comprises a plurality of coal-fired internal-combustion engines; and crankshafts of the plurality of coal-fired internal-combustion engines are arranged coaxially side by side; the adjacent crankshafts are connected by adopting a clutch to form a power shaft; and one end of the power shaft is in transmission connection with an input shaft of the generator. The invention aims to provide the coal-fired powder internal-combustion engines and the generator capable of regulating and controlling the generated energy, which have the advantages of oil resource conservation and high conversion rate of energy sources.

Description

technical field [0001] The invention relates to a pulverized coal-fired internal combustion engine and a generator with adjustable power generation. Background technique [0002] According to the global energy report, the current global oil reserves can only be used for 40 years, while coal can be used for 167 years, and the market price of coal is much lower than that of gasoline, diesel and kerosene. Therefore, further rational development and utilization of coal resources has very important practical significance. Internal combustion engine is a power output device widely used by human beings, but existing internal combustion engines cannot use coal as fuel. In addition, the existing power generation devices can only convert thermal energy into electrical energy with high efficiency at the rated power generation. When the electric energy required by the load decreases, the existing power generation devices cannot convert heat energy into electrical energy with high effic...

The internal combustion engine is a power output device widely used by humans, but the existing internal combustion engine cannot use coal as fuel

In addition, the existing power generation devices can only convert thermal energy into electrical energy with high efficiency at the rated power generation. When the electric energy required by the load decreases, the existing power generation devices cannot convert heat energy into electrical energy with high efficiency. Reduce the output of electric energy under the situation, which will lead to a lot of waste of energy
