Coal-to-gas plant conversion is gathering pace in the US

Oct 13, 2020 · Coal-to-gas plant conversion is gathering pace in the US and Canada. Repurposing aging coal plants to run on natural gas is increasingly considered a viable way for energy producers to reduce emissions and cut costs. More than 100 US coal plants were replaced or converted to run on natural gas between 2011 and 2019.

Boiler Efficiency - an overview | ScienceDirect Topics

Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses.

INCREASING THE ENERGY EFFICIENCY OF BOILER AND HEATER

At 80 percent boiler efficiency, this heat requires about 29.7 m 3 /h (1050 cu. ft./h) of natural gas, worth about $32,100 per year (based on 300 days per year at $0.15/m 3). Water-heating boiler systems, obviously, do not incur the blowdown costs. Maximize hot condensate return

Natural Gas Line Sizing using General Pressure Drop Equation

May 19, 2017 · Gas velocity = 33.18 ft/s; End pressure = 43.27 psia, or pressure drop = 0.43 psi (use equation 1) By using process simulator we got: Gas velocity = 34.18 ft/s; End pressure = 43.28 psia, or pressure drop = 0.426 psi; The result is similar too. BONUS! This is a spreadsheet I used to calculate line size of gas manually.

Natural Gas Fired Boilers

Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).? Steam and exit gas temperatures. Upon switching from coal to natural gas, heat transfer characteristics of a boiler will be impacted.
