Intro to Air-Fuel Ratio Control - Lesm

2015-1-23 · Combustion Terminology Combustion –The rapid oxidation of a fuel, usually via the oxygen present in air, resulting in the release of energy (heat and light). Combustion is the CONTROLLED rapid oxidation of a fuel. Explosion is the UNCONTROLLED rapid oxidation of a fuel. Stoichiometric Ratio –The perfect amount of oxygen and fuel mixed during combustion such that nothing is

How much fuel required for 1TPH boiler? - Quo

I will give you an example, so you can take this as reference and calculate fuel required for any capacity of Boiler for any fuel. Boiler Capacity - 1000 kg/hr Steam Pressure - 10.5 kg/cm2(g) Steam Temperature - 185.5 Deg c (Saturated Steam)- You

Combustion Efficiency and Excess Air - Engineering

2019-12-13 · 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

Coal Properties and its influence on Boiler Pankaj Ekbot

2013-11-27 · • Coal Properties Affecting Combustion • Fuel Ratio (Fixed Carbon / Volatile Matter) is commonly used to evaluate the combustibility of coals • More advanced analysis rely on macarel analysis and vitrinite reflectance for evaluating combustion performance • Firing Arrangements • Wall Fired • Front Wall • Front and Rear Fired
