A Guide to Energy-Efficient Heating and Cooling

Inspect the flue piping for rusting and any disconnections or evidence of back drafting. Check all gas (or oil) connections, gas pressure, burner combustion, and heat exchanger. Improper burner operation can be caused by a dirty burner or a cracked heat exchangereither can cause the equipment to operate less safely and efficiently.

Ventilation (architecture) - Wikipedia

The 1989 ASHRAE standard (Standard 62-89) states that appropriate ventilation guidelines are 20 CFM (9.2 L/s) per person in an office building, and 15 CFM (7.1 L/s) per person for schools, while the 2004 Standard 62.1-2004 has lower recommendations again (see tables below).

Boiler - Wikipedia

The steam piping is directed through the flue gas path in the boiler furnace, an area in which the temperature is typically between 1,300 and 1,600 degrees Celsius (2,372 and 2,912 degrees Fahrenheit). Some superheaters are radiant type, which as the name suggests, they absorb heat by radiation.

Particulates - Wikipedia

Particulates also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM), or suspended particulate matter (SPM) are microscopic particles of solid or liquid matter suspended in the air.The term aerosol commonly refers to the particulate/air mixture, as opposed to the particulate matter alone. Sources of particulate matter can be natural or

Condensing boiler - Wikipedia

Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.

Boiler Efficiency - an overview | ScienceDirect Topics

The biggest heat loss from a steam generator is the heat lost with the exiting flue gas. 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.

Furnaces and Boilers | Department of Energy

An all-electric furnace or boiler has no flue loss through a chimney. The AFUE rating for an all-electric furnace or boiler is between 95% and . older systems. The costs of retrofits should be carefully weighed against the cost of a new boiler or furnace, especially if replacement is likely within a few years or if you wish to switch to

Fireplace - Wikipedia

Ventless fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. [clarification needed] In the United States, some states and local counties have laws restricting these types of fireplaces.They must be properly sized to the area to be heated. There are also air quality control issues due to the amount of moisture they release into
