The VariflameTM burner delivers high-efficiency performance in gas-fired package boilers with NOx emissions as low as 20 ppm (41 mg/Nm3) at 3 percent O2. Using advanced air-fuel staging techniques, the Variflame burner can operate with or without flue gas recirculation (FGR). Reduces NOx, CO, VOC and particulate emissions

Air Pollution Control Technology Fact Sheet

>5MW for gas-fired boilers). SCR is a widely used technology for large gas turbines. b. Temperature: The NOx reduction reaction is effective onl y within a given temperature range. The optimum temperature range depends on the type of catalyst used and the flue gas composition.

Designing efficient, effective boilers - Specifying Engineer

Apr 14, 2014 · The products of combustion of natural gas include carbon dioxide and water vapor. In a conventional boiler, the flue gas temperature is kept above the flue gas dew-point (roughly 140 F) to prevent the water vapor from condensing in the boiler or exhaust stack and avoid corrosion of of cast-iron, steel, or copper components.

Introduction to the boiler house | Spirax Sarco

Class D - Diesel or gas oil. Class E - Light fuel oil. Class F - Medium fuel oil. Class G - Heavy fuel oil. Oil began to challenge coal as the preferred boiler fuel in the UK during the 1950s. This came about in part from the then Ministry of Fuel and Power's sponsorship of research into improving boiler plant. The advantages of oil over coal

HIGH FLUE GAS TEMPERATURE - Boiler and Pressure Vessel

Based on the numbers posted the boiler is less efficient by 2 or 3 percent because the higher flue temperature means less heat is being transferred. The draft over the fire should be checked. Ideally it should be -.01"W.C. The O2 reading is also a little high 4-5% would be more ideal.

1.3 Fuel Oil Combustion

Air comes inside a boiler at ambient temperature, i.e. around 25- 40 Degree Celsius depending upon the location. After combustion, combustion products, i.e. Water vapor, Carbon dioxide and other gases depending on fuel composition are formed. These flue gases heat the water and then leave the system through a Chimney.

Flue-gas stack - Wikipedia

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler

Your Ultimate Guide to Boiler Maintenance | RasMech

Before we get into boiler maintenance, lets talk efficiency. Boilers draw in the fresh air, heat it, and send it out the stack. Optimal conditions would generate the smallest amount of flue gas (exhaust gas that's expelled) at the lowest possible temperature. The boiler system takes in cold water, heats it to steam, and uses the heat.

Combustion - Cloudinary

Combustion takes place when fuel, most commonly a fossil fuel, reacts with the oxygen in air to produce heat. The heat created by the burning of a fossil fuel is used in the operation of equipment such as boilers, furnaces, kilns, and engines. Along with heat, CO 2 (carbon dioxide) and H 2 0 (water) are created as byproducts of the exothermic

Combustion Testing - Engineering ToolBox

From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% (E2). Assuming a fuel cost of $8.00/MMBtu, the annual savings are: Annual Savings = Fuel Consumption x (1–E1/E2) x Fuel Cost
