How can you reduce particulate matter in combustion processes?

3 Post-combustion control

A third way to reduce PM in combustion processes is to use post-combustion control devices and systems. These are technologies that capture and remove PM from the flue gas or exhaust gas after combustion. For example, you can use cyclones, electrostatic precipitators, fabric filters, or wet scrubbers to separate PM from the gas stream. You can also use selective catalytic reduction or selective non-catalytic reduction to reduce nitrogen oxides, which can contribute to secondary PM formation.

4 Monitoring and maintenance

A fourth way to reduce PM in combustion processes is to monitor and maintain the performance and operation of the combustion system and the control devices. For example, you can use sensors, analyzers, or meters to measure the PM concentration, the combustion efficiency, the fuel quality, and the operating parameters of the system. You can also use feedback loops, alarms, or indicators to detect and correct any deviations or malfunctions. You can also perform regular inspections, cleaning, and repairs to ensure the optimal functioning and durability of the system and the devices.

5 Alternative energy sources

A fifth way to reduce PM in combustion processes is to use alternative energy sources that do not rely on combustion. For example, you can use solar, wind, hydro, or geothermal energy to generate electricity or heat. You can also use hydrogen, fuel cells, or batteries to power vehicles or machines. These energy sources can reduce or eliminate PM emissions and also reduce greenhouse gas emissions and fossil fuel consumption.

6 Education and awareness

A sixth way to reduce PM in combustion processes is to educate and raise awareness among the stakeholders and the public about the sources, effects, and solutions of PM pollution. For example, you can provide training, guidance, or incentives to the operators, managers, or owners of the combustion systems and the control devices to improve their skills, knowledge, and practices. You can also communicate, inform, or persuade the consumers, regulators, or policymakers to adopt cleaner fuels, technologies, or policies to reduce PM emissions and exposure.
