Is this a steam boiler? Efficiency greater than 90%?
If it is still operating at full capacity, it would need to use more than 48 tons of water every day, and that doesn't take into account wastewater discharge and efficiency.
Electricity consumption. It shouldn't be much, right? Do water pumps and fans use electricity? Just look at the nameplate and calculate it.
I don't know about coal boilers. The natural gas boiler is designed to use approximately 150 nm3 of natural gas per hour for 2 tons.
Thermal power plants use coal, oil and natural gas. As a factory that produces electrical energy from fuel, its basic production process is as follows: the fuel is burned in the boiler, and the heated water is transformed into steam, which is transformed into steam. converts the chemical energy of fuel into thermal energymic. The steam pressure drives the rotation of the steam turbine, and the thermal energy is converted into mechanical energy, then the steam turbine drives the rotation of the generator, converting the mechanical energy into electrical energy. Thermal power plants are classified as follows: According to fuel: coal-fired power plants, oil-fired power plants, gas-fired power plants, waste heat power plants, power plants using garbage and industrial waste as fuel; temperature: the working fluids in the boiler are It is water. The critical parameters of water are: 22.064 MPa and 373.99 ℃ At this pressure and temperature, the density of water and steam is the same, which is called the critical point of water. The pressure of the working fluid in the furnace is less than this pressure and is called subcritical boilers, pressures above this are called boilersupercritical eras. The steam temperature in the oven is not lower than 593°C or the steam pressure is not lower. than 31MPa, which is called ultra-supercritical.
Medium and low pressure power plants (3.92 MPa, 450 degrees), high pressure power plants (9.9 MPa, 540 degrees), ultra high pressure power plants (13.83 MPa , 540 degrees), subcritical pressure power plants (16.77 MPa, 540 degrees), supercritical pressure power plants (22.11 MPa, 550 degrees); from the selection of parameters of supercritical or ultra-supercritical units that have been built and under construction at international and national level, for supercritical and ultra-supercritical units There is no hard limit, it is simply to know what the value of the parameter is. At present, domestic and international people generally think that as long as the main steam temperature reachesnt or exceeds 600°C, it is considered an ultra-supercritical unit. According to the prime mover: condensing steam turbine power plant, gas turbine power plant, internal combustion engine power plant, steam-gas turbine power plant, etc. depending on the energy produced, condensing steam plant (only produces electricity), thermal; power plant (produces electricity and heat); According to the installed capacity of power plants: small capacity power plants (less than 100 MW), medium capacity power plants (100-250 MW), large and medium capacity power plants (250-1,000 MW), power plants of large capacity (above 1,000 MW); thermal power plants. There are several types of wastewater produced: industrial wastewater, domestic wastewater, coal-containing wastewater, and acid-base wastewater. classification, and the processes are also different.
