The boiler steam-production controller will measure this decrease in pressure and will increase fuel flow to the boiler. In the case of a natural-gas-fired boiler, the controller will proportionally open the fuel control valve. As the fuel flow is increased, the combustion air flow must also increase in order to maintain safe and efficient

• The tune-up activity is the act of reestablishing the air-fuel mixture for the operating range of the boiler. Oxygen and unburned fuel (carbon monoxide is generally the indicative measurement) are balanced to provide safe and efficient combustion. Carbon monoxide (CO) concentrations are also measured to ensure proper burner operation.

Stock® Batch Scales are designed for measuring coal usage into stoker boilers. They are primarily used to feed multiple stokers through transition chutework such as the Stock® Conical® Distributor. Batch scales are typically mounted underneath each bunker outlet for gravity feed on to an internal feed belt that conveys coal from the inlet to a weigh hopper.

Flue Gas Analysis as a Boiler Diagnostic Tool Overview, and Traditional Application Combustion flue gas analysis has been used by Power Plant Operators for decades as a method of optimizing fuel/air ratio. By measuring the amount of excess oxygen and/or CO in the flue gases resulting from combustion, plant operators can operate at the best
Read MoreFlue gas analysis using a Nova flue gas analyzer will enable you to measure the concentrations of pollutants present and adjust burners on a boiler for optimal combustion. Nova exhaust gas analyzers are useful for environmental control, for general boiler maintenance, and also as a tool for reducing fuel costs.

For solid fuel:The accurate measurement of the flow of coal or other solid fuel is very difficult. The measurement must be based on mass, which means that bulky apparatus must be set up on the boiler-house floor. Samples must be taken and bagged throughout the test, the bags sealed and sent to a laboratory for analysis and calorific value determi-

Measurement of CO 2 in Flue Gases 6515 Series DS/6515–EN Rev. C 2 Fuel Economy and CO 2 Measurements Cost of fuel is a major item in the budget of all concerned with the operation of industrial boiler plant. If combustion is inefficient, fuel is wasted and money spent needlessly. Many industrial concerns have proved that significant savings
Read MoreBoiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.
