EXHAUST SYSTEMS - Stor-Erik

Exhaust Systems Well-designed exhaust systems collect exhaust gases from engine cylinders and discharge them as quickly and silently as possible. Primary system design considerations include: Minimizing resistance to gas flow (back pressure) and keeping it within the limits specified for the particular engine model and rating to

USING BOILER FLUE TEMPERATURE TO CALCULATE

The boiler will consume some 5,200 CFM of air and 16,750,000 BTU of fuel (natural gas or light oil). The flue temperature will run at approximately 270 degrees F. This capacity assumes that there is no mineral scaling or other fouling to affect heat transfer on the water side.

What is a Condensing Gas Boiler? | U.S. Boiler Company

Boiler Efficiency Ratings. An AFUE of 90% means that 90% of the fuel energy becomes heat for your home and the other 10% escapes either up the chimney or out through the boiler into the space where the boiler is located. The higher the rating, the greater your savings will be.

Understanding Combustion Efficiency and Combustion

Understanding Combustion Efficiency. These substances are called exhaust gasses. Most of the exhaust gas comes from chemical combinations of the fuel and oxygen. When a hydrocarbon-based fuel (Natural Gas) burns, the exhaust gasses include water (hydrogen + oxygen) and carbon dioxide (carbon +

Technical advice on boiler combustion control

Energy can be recovered from exhaust gases by transferring thermal energy from the high-temperature gases to boiler feedwater, or to the combustion air entering the boiler. Another aspect of exhaust-gas energy management, which is the focus here, is combustion management.Author: Noria CorporationExhaust Gas Temperature: Gas Vs. Diesel | It Still Runshttps://itstillruns.com/exhaust-temperature-gas-vs-diesel-7819560.htmlGasoline. Gasoline's chemical structure is not as heavy has diesel's structure, resulting in a fuel that burns at a lower temperature range. In the end, the exhaust temperature from gasoline combustion is only between 700 and 1,100 degrees Fahrenheit.

Propane vs. Natural Gas: Which Is Best for Your Home

BTU is a measure of heating efficiency in the case of propane vs. natural gas, propane has more than double the BTU rating (1030 to 2490). This means that, even if you are paying more for propane on a per-unit basis, the fuel youre buying will burn cleaner and heat your home with greater efficiency.
