Nov 24, 2017 · Just a brief explanation of the reason I choose to heat my home with coal. It is the least expensive and easiest way for me. And either the electric company or myself are going to ultimately use
Jul 17, 2017 · Adjust for the burner efficiency by dividing consumption at 100 percent efficiency by the burner efficiency rating. For a burner that is 95-percent efficient, divide by 0.95. In the example: 40,000 BTU divided by 1,075 = 37.21. Adjusting for burner efficiency: 37.21 divided by 0.95 = 39.17 cubic feet of natural gas consumed in one hour.
Bunker quantity is always said in Metric Ton (MT) because volume of oil changes according to the temperature , so it is always preferable to take bunker in weight which does not get changed with the change in temperature. But in actual scenario it's impossible to weigh the fuel oil physically . so we convert weight in to volume (m3).

Jun 04, 2020 · To calculate fuel consumption, start by writing down how many miles you have on your car and then filling up the gas tank. Then, drive your car around until the gas tank is nearly empty. When the tank is almost empty, refill it and write down how many gallons of gas you needed and how many miles you've driven since the last time you filled up.
May 15, 2011 · It's estimated 8% more fuel can be used on a return intercity trip when air conditioning is used for most of the journey. Therefore we recommend air conditioning is used sparingly. We have also found the largest contributor to excessive fuel consumption is the way the vehicle is driven.
How to Calculate Boiler Heat Input Rate. Depending on its energy source, a boiler may get its heat from the flow of electric current or from burning fuel. Each of these sources offer its own method for calculating the boiler's heat input rate.
Fuel consumption for diesel engines is normally more difficult to express than for petrol engines because of the vast variability in possible applications. Applications like stationary industrial, marine, automotive, and earthmoving are examples of this variability.
