Validated methods for flue gas flow rate calculation with
In one urea-based SNCR process (Nalco Fuel Tech NoxOut), an aqueous solution containing urea and chemical enhancers is injected into the furnace or boiler at one or more locations, depending on the boiler type and size. The urea reacts with NOx in the flue gas

1 Explanations about gas boilers 1.1 What is a gas boiler? A gas boiler is an appliance burning gas to produce heat that is transferred to water used for space heating and possibly sanitary hot water. In a gas fired boiler, gas is burnt in a combustion section. Heat is transferred to water through a heat exchanger after the combustion section.

Boiler Efficiency by indirect method = 100 Œ (L1 + L2 + L3 + L4 + L5 + L6 + L7 + L8) 1.7.2 Measurements Required for Performance Assessment Testing The following parameters need to be measured, as applicable for the computation of boiler effi-ciency and performance. a) Flue gas analysis 1. Percentage of CO 2 or O 2 in flue gas 2.
The most common test used for boilers is the flue gas analysis using an Orsat apparatus to determine the percentage by volume the amount of CO 2, CO, O 2, and N 2 in the combustion gas leaving the stack. Based on the flue gas composition and temperature, some adjustments can be made to tune-up the boiler and to determine the best air-to-fuel ratio to improve the boiler efficiency.
How to calculate the gas consumption of a gas boiler? 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), and the thermal efficiency is 92% (non-fixed value).
However, it is noted that the flue gas volume per unit of supplied energy, S (m3/MJ), is essentially invariant for a given fuel type and this is a better basis for calculation when compared with the flue gas volume per unit mass. The flue gas volume is derived from the
