Like all combustion-driven power sources, reciprocating engine generators are constantly under scrutiny for the emissions they generate, with combustion efficiency key to their effective operation.
Natural gas-powered engines are cleaner than traditional coal-fired boilers, having much lower emissions of sulphur dioxide (SO2) and carbon dioxide (CO2). As an added benefit, they can use renewable fuels such as biogas produced by anaerobic digesters.
The key pollutants from gas-powered applications are oxides of nitrogen (NOx) and carbon monoxide (CO). NOx and CO are harmful gases, with environmental regulations in place to confirm that they must be monitored in industrial processes. Oxygen (O2) is a required measurement to ensure that emissions can be adjusted to account for the dilution effect.
Monitoring O2 and CO also allows the ratio between air and fuel to be adjusted to achieve optimum combustion efficiency.
An integrated, all-in-one continuous emissions monitoring system (CEMS) provides several advantages to this smaller power generation process. It is easier to use than large-scale systems, and is far less expensive to install. The technology is well-proven and can be located close to the required measurement point.
APPLICATION NOTE
RECIPROCATING ENGINE GENERATORS
Reciprocating Engine Generators are a trusted method of providing reliable electric power for small-to medium-scale operations. Driven by the benefits of lower costs and risks, gas-powered reciprocating engines are increasingly being used in place of combined-cycle gas turbine power plants. Read More >
