Air Fuel Ratio Effect on Combustion Efficiency

23-10-2013 · Air Fuel Ratio Effect Combustion Efficiency and Air Fuel Ratio. Posted on October 23, 2013 December 15, 2017 by Bob Steinberg. In part two of this series on combustion control of industrial heat sources, we consider the air fuel ratio and the balance of using excess air to consume combustibles while minimizing energy from going up the stack in industrial heating sources. In Part I, Stoichiometric …

Boiler Efficiency and Combustion | Spirax Sarco

The control of the air/fuel mixture ratio on many existing smaller boiler plants is ‘open loop’. That is, the burner will have a series of cams and levers that have been calibrated to provide specific amounts of air for a particular rate of firing. Clearly, being mechanical items, these will wear and sometimes require calibration. They must, therefore, be regularly serviced and calibrated. On larger plants, ‘closed loop’ …

Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.: Figure 2.2 Fire Tube Boiler

Combustion Efficiency and Excess Air - Engineering ToolBox

The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Excess air to achieve highest possible efficiency for some common fuels: 5 - 10% for natural gas. 5 - 20% for fuel oil. 15 - 60% for coal. Carbon dioxide - CO2 - is a combustion

steam boiler questions and answers

Steam Boiler Questions and Answers

Can a Main Boiler built to fire 380 cst HFO, be fired with light crude oil directly from the cargo-tanks? Answer: A completely new fuel system is required, from deck to the burner rails of the boiler. To prevent any possibility of gasses leaking from flanges, there have to be ducting enclosing the entire fuel-system with forced draft fans that vent 30 times the volume of the trunking to the outside. Also there have to …
