Performance Test Codes - ASME

PTC 4.4, on Heat Recovery Steam Generators, provides a detailed rigorous calculation approach for testing of HRSG's. The test approach involves the determination of the gas turbine exhaust flow by two different means and combining the result. This would apply to multipressure HRSG's including units with auxiliary duct burners.

Selecting a Home Heating System - Energy Depot

In most parts of the country, natural gas is the most popular space heating fuel. In areas where natural gas is not available, many homeowners heat with propane or LP gas. Electric heat pumps are also a good option, particularly in less severe climates. Fuel oil is less common, but still used in some parts of the U.S., particularly in the

Boiler Efficiency - an overview | ScienceDirect Topics

The flue gas loss depends on the final flue gas temperature and the amount of flue gases. Thus the higher the air ratio, the higher the flue gas losses. The flue gases should leave the boiler at a temperature as low as possible to minimize the flue gas losses. Usually either economics, equipment, or corrosion issues limit the flue gas to 150

FUNDAMENTALS OF COMBUSTION AND HEAT LOSSES

FGT = flue gas temperature, ºF CAT = combustion air temperature, ºF HHV = higher heating value of fuel, Btu/lb. CO 2 and O 2 = percent by volume in the flue gas N 2 = 100 CO 2 O 2 C and S = weight fraction in fuel analysis. Minimizing excess air reduces dry flue gas losses.

Flue gas generated in the process of burning fuel by plants to generate heat or electricity can achieve temperatures anywhere from 50°C to 100°C. This means that flue gas can be condensed to preheat the DH return line before it gets to the plant. The temperature of the flue gas can be further condensed with the help of HPs until it decreases

Central heating - Wikipedia

Overview. Central heating differs from space heating in that the heat generation occurs in one place, such as a furnace room or basement in a house or a mechanical room in a large building (though not necessarily at the geometrically "central" point). The heat is distributed throughout the building, typically by forced-air through ductwork, by water circulating through pipes, or by steam fed

Orsat gas analyser - Wikipedia

An Orsat gas analyser is a piece of laboratory equipment used to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, the Orsat remains a reliable method of measurement and is relatively simple to use. It was patented before 1873 by Mr. H Orsat as the Ellison Orsat Apparatus.
