Flue gas treatment | technology | Britannica

The total amount of excess oxygen in the flue gases is (O - ½CO); hence N - 3.782 (O - ½CO) represents the nitrogen content in the air actually required for combustion and N ÷ (N - 3.782 [O - ½CO]) is the [Pg 158] ratio of the air supplied to that required. This ratio minus one will be the proportion of excess air.

ANALYSIS OF FLUE GASES - Project Gutenberg

Gas consumption = Gas boiler power /Fuel calorific value / Gas boiler heat value utilization. For example, we operate 1 ton gas boiler for 1 hour (full load). The boiler output is 600,000 kcal (fixed value), the natural gas calorific value is 36.22 MJ/Nm3 (fixed value), …

How To Calculate Natural Gas Boiler Consumption--ZBG

Jan 09, 2020 · About the 40-50% dilution air, do you mean 40-50% of the flow rate coming out of the boiler before the draft hood, or 40-50% of the total combined flow rate (flue gas from the boiler + dilution air)? To properly burn 1 cubic foot of natural gas, 15 cubic feet of air is needed for combustion (drawn in through the burner area) to meet excess air requirements for safe combustion.

CHAPTER 3 COMBUSTION CALCULATION

The flue gas leaves the boiler at 300oC (all the water formed will be vapour). In addition, a substantial amount of heat is also lost through the boiler wall and other uncounted sources. Calculate the flue gas composition (both dry and wet basis) leaving a boiler.

Boiler Economizer: Boost Your Boiler's Performance I RasMech

The condensing gas steam boiler produced by Fangfang uses a advanced condensation technology to set up a condensing recovery device near the flue. When the high-temperature flue gas passes through the device, the latent heat part encounters the condensed water to release heat, which is supplied to the boiler for absorption again. The thermal efficiency can be It is as high as 108%. In one year, it can save the company the fuel input cost of 50,000 to tens of thousands (depending on boiler

Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel. You can also refer to Thermodyne's Boiler Bible that provides you the general composition of above elements for various fuels.
