Boiler Combustion Solution for Reducing Fuel Costs

2017-2-9 · (1) Calculation of the fuel flow rate control setting value (see Fig. 1 (1)) Since the boiler outlet main steam flowrate signal initially changes when there is a change in the amount of steam used on the load-side of the boiler, the amount of fuel necessary for generating steam is calculated from this signal, and this value becomes the setting

Why is atomization with steam done in oil-fired

Fuel is atomized so that it will readily mix with the air and burn fully and quickly. If you shot a solid stream of fuel into a boiler, it would take a long time for all that fuel to burn completely, if you could get it to do so. If the fuel doesn

What are boiler efficiency and boiler evaporation ratio

2019-9-10 · Evaporation ratio = quantity of steam generation/quantity of fuel consumed.For example quantity of steam Is 310 ton/hr and fuel is 55 ton/hr then the evaporation ratio is 5.63. Evaporation ratio is also known as steam fuel ratio.A drop in evaporation ratio indicates drop in boiler efficiency.Boiler evaporation ratio depends on fuel quality.
