It analyzes the oxygen in the flue and adjusts the air- accordingly to maintain a set amount of excess oxygen These controls are usually installed on larger with high annual usage and can increase energy efficiency by one or two percent beyond what is achieved with the standard control alone Monitor Gauges

The importance of proper gas combustion control - EE

84% 32:1 (31%) The point where all oxygen is consumed and all fuel burned is defined as the stoichiometric point (see Fig 1) The stoichiometric combustion point is the air to fuel ration which gives complete combination of the gas and the oxygen in the air to form carbon dioxide (CO 2) and water (H 2

Best Practices for Achieving the Perfect Air-to-Fuel Ratio

The first step to understanding how to cut down on burner energy costs is to understand what an air-to- is Simply put an air-to- is the measure of air compared to involved in the combustion process For safety reasons knowing what the air-to- curve is on your burner system is critical

A proper air/fuel gas ratio will result an optimal performance out of the boiler It can produce steam at a rate of It is estimated

Optimal Combustion Process - Fuels and Excess Air

Power plant boilers normally run about 10 to 20 percent excess air Natural gas-fired boilers may run as low as 5 percent excess air Pulverized coal-fired boilers may run with 20 percent excess air Gas turbines runs very lean with up to 300 percent excess air Typical values of excess air for some commonly used fuels are shown in the table below:

Boiler Firing Controls Functional Specification

Combustion is controlled by adjusting the flow and combustion air flow to meet demand for steam while maintaining the proper of air to The demand signal from the Master (discussed in the next section) sets the flow The combustion air demand signal comes from the air-to- controller which sets the air flow The simplest control scheme would set the flow to meet the demand for steam and set the air flow in to the

What are boiler efficiency and boiler evaporation ratio

Evaporation ratio = quantity of steam generation/quantity of fuel consumedFor example quantity of steam Is 310 ton/hr and fuel is 55 ton/hr then the evaporation ratio is 563 Evaporation ratio is also known as steam fuel ratioA drop in evaporation ratio indicates drop in boiler efficiencyBoiler evaporation ratio depends on fuel quality
