These systems draw combustion air directly from outside the house.

The combustion air fan is shut down after a period of time.

Hot gas turbine exhaust is used as the combustion air.

How can we regulate the flow of combustion air through this pipe?

Today many industrial processes use preheated combustion air for fuel economy.

Combustion air is drawn in via a cyclone filter system.

Some of these filters are rectangular and similar in shape to the combustion air filter.

The power to drive the combustion air compressor comes from the jet's own turbines.

The main application for air filters are combustion air to engines.

Below the burner, the hot lime transfers heat to, and is cooled by, the combustion air.

This created a draw of combustion air into the boiler and an exhaust to the chimney.

We inserted a plumber's plug in the opening on the outside, but this cut off all combustion air to the fireplace.

Primary air This is the main combustion air.

The airflow is then reversed, so that the hot bricks heat up the incoming combustion air and fuel.

If a house is made relatively airtight and not enough combustion air is provided for these fuel-burners, problems can result.

The implementation of cooling air has to be carefully designed so it does not directly interact with the combustion air and process.

The hot air is used as preheated supply of combustion air in the kilns.

The desired amount of excess combustion air needed to assure complete combustion.

The jet engine's turbines power the combustion air compressor.

This combustion air was passed through the Air Heater which increased its temperature.

Combustion air generally enters at the base, and the airflow is usually controlled by damper doors.

The denser column of ambient air forces combustion air into and through the boiler.

Atmospheric vented systems us room air as combustion air and exhaust air.

Secondary combustion air is supplied into the boiler at high speed through nozzles over the grate.

Gas turbine systems compress the intake combustion air.
