Prepare Your Gas Plant for Cold Weather Operations. The temperatures in the Electric Reliability Council of Texas (ERCOT) region during the systemwide emergency ranged from 11F to 35F, equivalent to –5F to the low teens when the wind chill factor is considered. In Austin, temperatures remained below freezing for over 70 consecutive hours.
Natural Gas fired (including LNG fired) power plants account for almost 20 % of the world’s electricity generation. These power plants use Gas Turbines or Gas Turbine based combined cycles. Gas turbines in the simple cycle mode, only Gas turbines running, have an efficiency of 32 % to 38 %.
Coal power plants primarily rely on steam-driven generating units. In contrast, power plants fueled by natural gas rely on a variety of technologies. Natural gas-fired generating units driven by combustion turbines or steam turbines accounted for about 28% and 17%, respectively, of total natural gas-fired capacity in 2015.
Natural gas power plant. All natural gas plants use a gas turbine; natural gas is added, along with a stream of air, which combusts and expands through this turbine causing a generator to spin a magnet, making electricity. There is waste heat that comes from this process, because of the second law of thermodynamics.
Repowering (in non-solid fuel steam power plants) is adding gas turbine(s) to steam cycle power plants, which is the common procedure for completing the life of old steam cycle sectors . To achieve sufficient efficiency, this operation must be done economically and with lower costs.
Steam-electric power station. Almost all coal, nuclear, geothermal, solar thermal electric power plants, waste incineration plants as well as many natural gas power plants are steam-electric. Natural gas is frequently combusted in gas turbines as well as boilers. The waste heat from a gas turbine can be used to raise steam,
Combined Cycle Gas Turbines increase efficiency by adding a boiler to recover the gas turbine exhaust heat, which heat is used to drive a steam turbine. This gas steam combination increases overall efficiency to 50–60%. Most large gas power plants are combined cycle.
Oct 28, 2013 · It will vary somewhat depending on the plant, but for the most part the steam produced by the boilers will serve one of the following functions: Fuel – Often the steam will be used to power turbines for electric generating equipment, blowers, and pumps.
Gas boiler burners consume fuel based on their BTU output. Natural and propane gas have specific levels of energy contained within them. One cubic-foot of natural gas contains 1075 BTUs of energy. However, Gas boiler burners are not 100-percent efficient. If you know the burner efficiency, you can calculate the exact fuel consumption per the output of the burner.
The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas.
Efficiency. The efficiency of the steam turbine power plant depends on the type of fuel used in the boiler. The efficiency of coal-powered plants ranges from 32–42% depending on the pressure and temperature of the steam . The efficiency of advanced coal generation plants, however, can approach 50% .
