Problems solved by technology

The disadvantages are: it takes a long time to prepare for raising the fire, and the boiler must be kept in a hot standby state when it is temporarily stopped, the thermal efficiency is low, and the device is cumbersome
[0005] 2. Wood-burning engine technology. During World War II, there were a large number of automobile, motorcycle, and tank engines fueled by firewood, coal, and charcoal. They mainly pyrolyzed, cracked, and gasified wood and other biomass materials to generate Gases such as wood gas are cooled, purified, and compressed before being sent to a special engine for combustion. This technology is phased out after the development of the petroleum industry due to unstable power output, large exhaust pollution, and long start-up time. With the rise of oil prices and Oil and gas resources are exhausted, and now some inventors are studying and improving this technology
[0008] 5. There are many monographs on the development of hydrogen energy technology, the most notable of which is fuel cell vehicle technology, including high-efficiency high-temperature electrolytic cells; but all current hydrogen energy technologies involve hydrogen production, conversion, storage, transportation, etc. There are many technical bottlenecks in various links, such as the construction of hydrogen refueling stations; the same is true for pure electric vehicles, such as the construction of charging piles, battery weight, charging time, cruising range, etc. There are many problems, and there is no ideal solution , the development and promotion are greatly restricted

Embodiment 1

[0030] To improve a certain fuel cell truck, adopt figure 1 The system shown uses two American-made STM4-120 engines with a total output power of 50KW. The hot chamber is properly improved to facilitate pure oxygen combustion, remove ashes and deal with exhaust gas. The cold chamber adopts an air cooling system; the fuel is pre-heated. Extruded crop straw materials soaked in lime water in batches are fed at a rate of 20 kg per hour. The generated power is connected to the SOEC high-temperature electrolytic cell to electrolyze water, and the obtained pure oxygen is connected to the combustion chamber (combined with the thermal chamber) Combustion-supporting, SOEC high-temperature electrolytic cell produces hydrogen, which is connected to fuel cell to generate electricity with air, and drives the vehicle power system through the output of inverter power supply, while retaining a certain capacity of battery to adjust power output and ensure the use of engine warm-up, climbing, ac...

Embodiment 2

[0032] Power supply is difficult in a remote forest area, but biomass materials such as forest trees are abundant, so the figure 2In the system shown in the figure, the trees are not easy to burn in the air due to their high moisture content just after felling; the branches and other materials are sent to the fuel pretreatment device to be pulverized and sprayed with a certain amount of lime powder to mix evenly, and sent to the steam generating boiler through the conveying device The pure oxygen combustor in the boiler burns and heats steam in pure oxygen to generate a boiler. The steam in the boiler is heated by a heat pipe and connected to a micro-turbine generator set with a power generation power of 10 to 20 kilowatts to generate electricity. Part of the electric energy is directly output for use, and some of the electric energy After rectification, it is connected to a large-flow hydrogen-oxygen generator, and the pure oxygen generated is connected to the pure oxygen com...

Embodiment 3

[0034] Take the modification of BYD F1 electric vehicles as an example. The curb weight of the original model is 1.4 tons, the speed is 100 kilometers per hour, and the power consumption per 100 kilometers is 10 to 12 degrees per hour; 4 oxygen cylinders of 270 kg (including 32 kg of oxygen, about 24 cubic meters), or Dewar bottles of 300 kg (including 200 kg of liquid oxygen), the curb weight increased to 2.3 tons, and the power consumption per 100 kilometers increased from 10-12 degrees to 17-10 degrees 22 degrees, with a 25KW engine generating 25 degrees per hour is enough to supplement. Stirling machine (US STM4-120 type) cost increased by 100,000 yuan. A 25 kW Stirling engine generates electricity per hour at 25 degrees and consumes 15 kg of firewood and 8 kg of high-pressure oxygen (about six cubic meters in one bottle), and the cost per 100 kilometers is more than 20 yuan; load 150 kg of wood and a Dewar bottle of liquid oxygen It can run thousands of kilometers in 10 ...
