Improve Your Boiler's Combustion Efficiency

On well-designed natural gas-fired systems, an excess air level of 10% is attainable. An often-stated rule of thumb is that boiler efficiency can be increased by 1% for each 15% reduction in excess air or 40°F reduction in stack gas temperature. Suggested Actions Boilers often operate at excess air levels higher than the optimum.

Waste Heat Boilers - Clarke Energy

Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as 'high grade heat', contrasting to 'low-grade heat' available from the generator cooling circuits. This high temperature and flow makes it well

Use Feedwater Economizers for Waste Heat Recovery

Boiler heat output = 45,000 lb/hr x (1,195.5 – 84.97) Btu/lb = 50 million Btu/hr The recoverable heat corresponding to a stack temperature of 500°F and a natural gas-fired boiler load of 50 MMBtu/hr is read from the table (above) as 4.6 MMBtu/hr. Annual Savings = (4.6 MMBtu/hr x $8.00/MMBtu x 8,400 hr/yr)/0.80 = $386,400 Suggested Actions

Fossil fuel power station - Wikipedia

A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity.Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.
