Prandtl Number - an overview | ScienceDirect Topics

Gas transport properties for the products of combustion of the common fuels, fired at normal excess air at or near-full boiler load, may be obtained from Tables 10.110.4. Non-luminous gas radiation has a small overall effect in the convective section, typically 25% of total convection.

Water heating - Wikipedia

Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses.. Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers.

Heat Exchanger Fouling Factor - EnggCyclopedia

Heat exchanger fouling is caused by a variety of reasons such as corrosion, precipitation, accumulation of dirt or particles, accumulation of biological material etc. Depending on the kind of fouling, different kinds of solid material will accumulate on the walls of the heat exchanger.. Fouling factor (or dirt factor) definition. Heat exchanger fouling factor quantifies the effect of fouling

Coolant - Wikipedia

Gases. Air is a common form of a coolant. Air cooling uses either convective airflow (passive cooling), or a forced circulation using fans.. Hydrogen is used as a high-performance gaseous coolant. Its thermal conductivity is higher than all other gases, it has high specific heat capacity, low density and therefore low viscosity, which is an advantage for rotary machines susceptible to windage

Heating boiler aquastat control diagnosis, troubleshooting

Oil Burner Short Cycling Traced to Poor Aquastat Temperature Sensor Contact: use the heat conductive grease. We have observed occasional short or sporadic oil burner (and some gas burner) "on" cycles that were hard to track down. Technicians even replaced aquastats on a test system we've been monitoring, only to have the problem continue.

Steam Tracing - an overview | ScienceDirect Topics

Meherwan P. Boyce, in Gas Turbine Engineering Handbook (Fourth Edition), 2012 Stream Tracing Systems. Steam tracing is the most common type of industrial pipe tracing. In 1960, over 95 percent of industrial tracing systems were steam traced. By 1995, improvements in electric heating technology increased the electric share from 30 to 40 percent, but steam tracing is still the most common system.
