Therefore, in practice more air than ideal must be supplied to burn all fuel completely. The amount of air more than the theoretical requirement is referred to as excess air. Power plant boilers normally run about 10 to 20 percent excess air. Natural gas-fired boilers may run as low as 5 percent excess air.

Online Combustion Air Calculations: Air quantity is calculated keeping in mind the complete combustion of fuel, so for the complete combustion of fuel excess air is kept to around 20% - 50% depending upon the type of fuel, size of fuel particles and degree of mixing.Check other online calculators at Thermodyne Boilers
from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox, the recirculated gas is mixed with combustion air prior to being fed to the burner. The recycled flue gas
Post-combustion process control generally consists of the use of baghouses and filters in the case of solid fuel firing, and selective catalytic reduction (SCR) process to reduce NOx in gas and oil fired boilers. SCR works well, which is why all vehicles have catalytic converters.

The Small Boiler NSPS also dictate record keeping requirements regarding fuel usage for all fuels, including natural gas. Record keeping requirements and compliance standards for the different emissions depends on the type of fuel fired and on the boiler size.
Incomplete combustion of natural gas. Can you imagine operating a gas-fired furnace at 25 million Btu/hr and not knowing that another four or five million Btu/hr of natural gas was going up the chimney without burning? Can you imagine it going on for months?
Boiler maintenance In general, a gas boiler is easier and less expensive to maintain than an oil one. An oil boiler needs to be serviced more frequently to prevent leaks, and if leaks do happen it becomes an expensive issue to fix. However, new oil boilers are a lot

Oct 27, 2016 · Boilers don't exactly “leak” carbon monoxide, they actually create it. Without getting overly technical, CO is a product of incomplete combustion due to insufficient availability of oxygen.
The burning of natural gas is cleaner than the burning of oil and coal. When gas is burned with insufficient combustion air some volatile hydrocarbons can be created, which could become a safety hazard; care should be taken to avoid dangerous conditions.
Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm (0.001 in). Coal burns in suspension, like the combustion in an oil- or gas-fired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired

service and seldom is testing is done on gas, coal, or wood burning appliances. These kits generally consist of a stack thermometer, draft gauge, wet chemical CO 2 gas tester, slide rule and smoke pump. Although this equipment has served the industry well over the years, faster, more accurate, real time flue gas analysis is necessary.

The guy stuck a probe in the flue of my oil boiler and gas water heater. He showed me Carbon Monoxide levels from the water heater was reading 10ppm and the boiler was 340ppm. He said the boiler was way over the acceptable level (100ppm) and I should call someone for a tune up.
Gas-Fired Power Generation Gas-fired power generation should be a key factor in the extent and rate of development of China’s gas market, as it has the potential to create the initial bulk downstream revenue that typically anchors investment upstream of it. A baseload gas-fired power station can absorb large quantities of gas, quickly.

Oil Burner Puffbacks cause, cure and prevention: This article explains the cause, cure, and prevention of potentially dangerous and sooty oil fired heating equipment puffbacks that can occur at an oil fired boiler, furnace, or water heater. We explain why puffbacks can be dangerous, as well as expensive.
industries. As of 1980, there were approximately 1,600 wood-fired boilers operating in the U. S., with a total capacity of over 1.0 x 10 11 Btu/hour. 1.6.2 Firing Practices 5-7 Various boiler firing configurations are used for burning wood waste. One common type
Jack Schilling, application consultant with Honeywell IAC (Fort Washington, Pa.) explains it like this, ‘The fuel savings between operating with 5% excess oxygen and 8% excess oxygen can be hundreds of thousands of dollars per year. For example, a natural gas fired boiler operating with 8% excess oxygen is usually about 76% efficient.

Stoichiometric combustion is a theoretical point where optimum levels of oxygen and fuel mix to achieve maximum combustion efficiency in industrial boilers. In part one of this five-part series, we discuss stoichiometric combustion, that theoretical position in which ...
This additional air is called ''excess air''. A boiler firing at 1.2 times the stoichiometric air requirement would be said to be firing at 20 percent excess air. If insufficient oxygen is introduced into the furnace, incomplete combustion of fuel will occur. This wastes fuel, causes air pollution, and results in hazardous conditions in the boiler.
