  • Heat Distribution Systems | Department of Energy

    Steam heating is one of the oldest heating technologies, but the process of boiling and condensing water is inherently less efficient than more modern systems, plus it typically suffers from significant lag times between the boiler turning on and the heat arriving in the radiators.Learn More

    Apr 25, 2020 · boiler horsepower – Sizes The earliest such measure of boiler output, the "nominal or rated boiler horsepower," was simply based on the area of the boiler's heating surface. Each 10 square feet of surface represented 1 boiler horsepower, so a boiler with 100 square feet of heating surface would be rated at 10 boiler horsepower.Learn More

  • Caustic corrosion in boilers - Lenntech

    4. some mechanisms, such as a slight leak, must be present to allow the boiler water to concentrate on the stressed metal. Stem blanketing is a condition that occurs when a steam layer forms between the boiler water and the tube wall. Under this condition, insufficient water reaches the tube surface for efficient heat transfer.Learn More

  • Oxy-fuel combustion in circulating fluidized bed boilers

    Jul 15, 2014 · The heat transfer is the same in the oxy-fired boiler (because the bed temperature and fluidization velocity are the same, so the vertical particle distribution is the same), but, since the furnace is smaller in this case, the heat absorption will be smaller in the furnace if the same principle of allocation of heat-transfer surface is applied Learn More

  • Foaming and priming in boilers - Lenntech

    Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain types of Learn More

  • What is Descaling? - Definition from Corrosionpedia

    Apr 23, 2015 · A descaling agent or chemical descaler is used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters and kettles. Descaling agents are typically acidic compounds such as hydrochloric acid that react with the alkaline carbonate compounds present in the scale, producing carbon dioxide gas and a Learn More

  • 1.3 Fuel Oil Combustion

    surfaces in the furnace (which houses the burner flame) absorb heat primarily by radiation from the flames. The tube surfaces in the boiler passes (adjacent to the primary furnace) absorb heat primarily by convective heat transfer.

    Thus you would be allowed 900 sq.ft. of boiler heating surface area for the wood fired unit and still be below the 90 bhp permitting threshold in 5-401 of the regulations. Since most boiler manufacturer's get a boiler horsepower out of 5.5 or 6 sq.ft. their bhp rating is likely well over 90 bhp but by our definition it would still be less.Learn More
