Heat combustion propane

Heat inputs (propane) and outputs (combustion exhaust gases) were monitored. [Pg.330]

Many homes in rural America are heated by propane gas, a compound that contains only carbon and hydrogen. Complete combustion of a sample of propane produced 2.641 g of carbon dioxide and 1.442 g of water as the only products. Find the empirical formula of propane. [Pg.122]

This category comprises conventional LPG (commercial propane and butane), home-heating oil and heavy fuels. All these materials are used to produce thermal energy in equipment whose size varies widely from small heaters or gas stoves to refinery furnaces. Without describing the requirements in detail for each combustion system, we will give the main specifications for each of the different petroleum fuels. [Pg.232]

The CIS and trans forms of 1 2 dimethylcyclopropane are stereoisomers Stereoisomers are isomers that have their atoms bonded m the same order—that is they have the same constitution but they differ m the arrangement of atoms m space Stereoiso mers of the cis-trans type are sometimes referred to as geometric isomers You learned m Section 2 18 that constitutional isomers could differ m stability What about stereoisomers We can measure the energy difference between as and trans 1 2 dimethylcyclo propane by comparing their heats of combustion As illustrated m Figure 3 20 the two compounds are isomers and so the difference m their heats of combustion is a direct measure of the difference m their energies Because the heat of combustion of trans 1 2 dimethylcyclopropane is 5 kJ/mol (12 kcal/mol) less than that of its cis stereoisomer it follows that trans 1 2 dimethylcyclopropane is 5 kJ/mol (12 kcal/mol) more stable than as 1 2 dimethylcyclopropane... [Pg.124]

Fuels ndEfficiency. Natural gas, oil, and electricity are the primary sources of energy propane is used as backup reserve in emergencies. Natural gas is the least expensive and most frequently used fuel, with heat content ranging from 34—45 MJ/nf (900—1200 Btu/ft ) for raw gas and approximately 3 MJ/m (80 Btu/fT) for air-gas mixtures. Fuel oil has heat content between 39—43 MJ/L (139,600—153,000 Btu/U.S. gal). Fuel oil is viscous at low temperature and must be heated before being fed to atomizing burners where it is mixed with air for combustion. [Pg.306]

If 10 tons of propane exploded with an explosive efficiency 0.05, 1,000 ft from you, what would be the peak positive overpressure Referring to equation 9.1-24, W = 0.0.5 ZE4 5E4/4,7E3 = 1E4 lb, where the heats ot combustion are from Table 9.1-4, and 10 tons is 2E4 lb. The scaled range is = 1000/IE4 = 45.6 from which a positive overpressure of 2... [Pg.340]

For propane, heat of combustion = 46300 kJ/kg and = 0.95. With an emissivity of = 1, the following expressions for fireball diameter and duration can be given ... [Pg.174]

On complete combustion at constant pressure, a 1.00-L sample of a gaseous mixture at 0°C and 1.00 atm (STP) evolves 75.65 kj of heat If foe gas is a mixture of ethane (C2H6) and propane (C3Hg), what is foe mole fraction of ethane in foe mixture ... [Pg.223]

Finally, we come to the effects of the Lewis number. Figure 4.2.14 shows the intensified images of vortex ring combustion of lean and rich propane/air mixtures. Since the flame is curved and stretched at the head region, the mass and heat is transferred through a stream tube. [Pg.54]

Heat Release Rate From Fuel Gas. The fuel gas used in these tests was a mixture of natural gas supplied by the local gas company. This gas mixture contains approximately 90 percent methane and small fractions of ethane, propane, butane, C02, and nitrogen, as analyzed by Brenden and Chamberlain (6). Although composition of the gas changes with time, the changes were small in our case. A statistical sample of gross heat of combustion of fuel gas over several months showed a coefficient of variation of 0.7 percent. Also, the gross heat of combustion of natural gas reported by the gas company on the day of the test did not vary significantly from test to test. Thus, we assumed that the net heat of combustion was constant. [Pg.420]

Compute the enthalpy of formation of propane at 25 °C from its chemical reaction with oxygen and its ideal heat of combustion given in Table 2.3. [Pg.43]

The required heat for the brazing cycle shall be produced by a controlled fuel gas flame. The fuel gas (e.g., acetylene, propane, or natural gas) is to be combusted with air, compressed air, or oxygen. The specific combination selected is dependent on the amount of heat required to bring the particular components to the brazing temperature in the required time. [Pg.61]

Oxygen is always a reactant in combustion reactions, which often release heat and light as they occur. Combustion reactions frequently involve hydrocarbon reactants (like propane, CgHgf ), the gas used to fire up backyard grills) and yield carbon dioxide and water as products. For example,... [Pg.123]
