Excess Air: Is it Such a Big Deal?

Setting up combustion systems for too much excess air (or dilution air) wastes fuel. Here's how to know if you are wasting natural gas in your industrial oven.

It's a well-established fact that setting up combustion systems for too much excess air (or dilution air) wastes fuel. You can use this relationship to calculate just how much you can save by decreasing excess air:

% Fuel Savings = 100 x [1- (Available Heat, High XS Air/Available Heat, Low XS Air)]

Crunch Time?

Faced with rising natural gas prices, processors should look for ways to cut energy consumption and increase energy efficiency. Here are some ideas from combustion expert Dick Bennett.

Burner History 105: How Industrial Burners Evolved for Modern Process Heating Applications

While nozzle-mix burners eliminated flashback, another concern was on the rise: NOX. Staged combustion and controlled airflow and gas flow allow efficient combustion for industrial process heating equipment.

Convection: A Series on the Principles of Industrial Heat Transfer

Convection is the transfer of energy via a moving fluid, and by fluid, I mean a liquid, vapor or gas.

It seems incredible that in seven-and-a-half years of writing this column, I've never gotten into a discussion of convection heat transfer. After all, it is the way most ovens and dryers heat the products they contain. Well, better late than never.

Clean Air Action: Contaminants Can Choke Your Combustion System

Years ago, a colleague who had done his share of service calls remarked, "The three biggest problems in keeping combustion systems operating are, one: dirt, two: dirt and three: dirt." I'm inclined to agree.

I'll wrap up this series of columns with a look at some more ratio control systems. These are less used on ovens, dryers and low temperature processes, but you may run into them where special conditions require their unique features.
