As with all other comparisons of heating with natural gas versus electricity, when electricity is produced via a heat engine (i.e. a turbine at a heat-powered power plant such as a coal, natural gas, nuclear, or geothermal electric plant), about two thirds of the energy in the heat sour...

Some compressor stations are operated by using an electric motor to turn the same type of centrifugal compressor. This type of compression does not require the use of any of the natural gas from the pipe, but it does require a reliable source of electricity nearby. Reciprocating natural gas ...
The submission of the equipment for CE acceptance testing by a “Notified Body” also includes measurement of the field of operation (boiler resistance versus heat output) and emissions of NOX and CO. Sizes above 3 MW will need to be tested on the actual hot water boiler because the ...
This explains the higher response of the NTs towards isopropanol and acetone vapors when compared to one versus ethanol. Moreover, a stochastic combination of NT-to-NT contacts at each chip segment underlies the diversity of their gas-sensing properties along the array that allows us to build th...
and 20% relative humidity, as measured in current versus CO concentration, where sensors having a larger size show a higher current responses. FIG. 6A also shows current signal response for varied concentrations of methane and propane, to demonstrate that sensor response is not interfered with ...
The fuel purification system consists of electric heaters followed by four MAPX-20 centrifuges operating in parallel. This plant is demonstrating the "purification" process which, to date, at this plant, has not required additional water to be added to the fuel, and only 20 gph are ne...
In accordance with the invention, a vertical nickel cylinder was loaded with a bed of K3NiF6prepared as described above. The bed had a length of 16" and a diameter of 2". The cylinder, which was provided with adjustable electric heaters, had an inlet for introducing a gas stream to th...
Configure the flow according to the FPD filter installed (phosphorus versus sulfur). FID and NPD jets: Use the jet appropriate for the type of column installed (capillary column versus packed column). NPD bead type: Always configure the NPD bead type. An incorrect type can lead to poor ...
