Traditional energy and coal periodicals

Coal is the main energy source today, and about 40% of the global electricity comes from coal-fired power generation. Coal is produced by prehistoric plants buried underground. Millions of years later, the decaying plants in the crustal movement turned into combustible coal.

First, most coal seams are stored in cracks in other rocks. Miners drill holes in different positions between rocks, then mix ammonium nitrate and diesel oil, and inject an appropriate amount of explosive liquid into the holes, and then block the holes with mud to bear the explosive force, which can guide the impact force on the side of the explosion point and ensure that the rock layer is washed horizontally and vertically at the same time. Workers put detonators in each hole, then connect all detonators with leads, and then detonate them with charges. Of course, the explosion delay will be set to let each detonator explode one after another, so that the continuous explosion is more powerful than the simultaneous explosion. The explosion broke the rock stratum.

Second, a miner who exposed the coal seam used a huge excavator to clean the gravel soil, exposing a solid and hard coal seam. From the side of the mine, we can see how many rocks are covered on the coal seam. The front loader loads the coal mine into a coal truck, and a coal truck can transport 220 tons of coal from the mine to the warehouse at a time, so that the coal can be sent to the warehouse. In a nearby power plant, when a company prepares to mine a coal mine, it needs to clean up the surface vegetation and soil layer first. As part of land reclamation, the company will store the topsoil until the end of coal mining, then refill the mine with topsoil and rocks, and then plant vegetation.

Third, the power plant is located next to the artificial lake, so it is convenient to take water for heating and generate steam for power generation. After the coal mine is sent to the power plant, the crusher breaks it into baseball-sized coal blocks, which can increase heat energy to produce coal, which can be transported to the indoor warehouse by conveyor belt and then into the boiler. At the same time, a huge pump pumped water from the lake. The furnace heats the water inside to 537 degrees Celsius, far exceeding the boiling point, and turns the water into high-pressure steam. Steam enters the rotating turbine, which makes the coil rotate to generate electricity. The temperature of steam left in the turbine is lower than 50 degrees Celsius, and it is compressed to a vacuum state.

Fourthly, after passing through a cooling condenser filled with water, the residual heat is absorbed by water, and once the steam is reused as liquid water, sulfur dioxide will be produced when coal is burned. The power plant will inject waste gas into a container filled with lime to neutralize sulfide, and the water vapor generated by chemical reaction will be recovered. Out of the room. The cable extend from that turbine generator can transmit power to the outdoor transform, and the outdoor transformer boosts and converts the pow to reduce the transmission power loss. At this time, the heat in coal can be transported to thousands of households through transformers.
