- Railway Preservation News • View topic - Oil versus Coal - RyPN
Railroads in the Southwest tended to use oil because there was oil being pumped out of the ground in their neighborhoods, while coal deposits were more remote, and the costs of transportation tipped the scale in favor of oil

15 - 60% for coal Carbon dioxide - CO 2 - is a combustion product and the content of CO 2 in a flue gas is an important indication of the combustion efficiency Optimal content of carbon dioxide CO 2 after combustion is approximately 10% for natural gas and approximately 13% for lighter oils
- 1. 3 Fuel Oil Combustion - US EPA
Emissions from fuel oil combustion depend on the grade and composition of the fuel, the type and size of the boiler, the firing and loading practices used, and the level of equipment maintenance Because the combustion characteristics of distillate and residual oils are different, their combustion can produce significantly different emissions
- Fuel energy density: What is it and why is it important?
Liquid fuels derived from oil occupy a uniquely advantageous position: a combination of high mass and volumetric energy density Those attributes are the principal reasons why motor gasoline and diesel fuel replaced solid fuels such as wood and coal in applications such as transportation
- 1. FUELS AND COMBUSTION - Bureau of Energy Efficiency
the type of coal while calorific value of fuel oils are much more consistent The typical Gross Calorific Values of some of the commonly used liquid fuels are given below:
- Synchronizers and gear oils - Transmission, Driveline, Hybrid . . .
1) How much of a difference does a GL-4 vs a GL-5 oil affect synchronization and synchro wear? 2) I see some mfrs using more double- and triple-cone synchros and others recommending friction modifiers to add to the gear oil
