Calculate a) Gross calorific value, moist basis b) Net calorific value, dry basis c) Net calorific value, moist basis d) Gross calorific value, dry basis using Dulong formula. = 32060.2 KJ/Kg NCV = GCV – 24.44(9×%H + %M) = 30630.26 KJ/Kg Thus NCV = 0.955 times GCV in this case. 3. Note: Change in basis increases CV.

Therms and Mcf of natural gas Carbon dioxide emissions per therm are determined by converting million British thermal units (mmbtu) to therms, then multiplying the carbon coefficient times the fraction oxidized times the ratio of the molecular weight of carbon dioxide to carbon (44/12).

WACC is calculated by multiplying the cost of each capital source (debt and equity) by its relevant weight, and then adding the products together to determine the value. In the above formula, E/V represents the proportion of equity-based financing, while D/V represents the proportion of debt-based financing.

As a rule of thumb you would need about 138 Kg of coal (26GJ/Ton) to produce 1 ton of steam. About 800 – 1,100 lbs (364 – 500 kg) of coal to generate 1 MWh of electricity.

Best Answer: GCV (gross calorific value) is the quantity of heat produced by combustion when the water produced by combustion is allowed to return to the liquid state. NCV (net calorific value) is the quantity of heat produced by combustion when the water produced by combustion remains gaseous.

Answer: This is because,NCV (net calorific value) is the quantity of heat produced by combustion when the water produced by combustion remains gaseous. Since water releases heat when it condenses, GCV is clearly bigger than NCV.

The coking process consists of heating coking coal to around 1000-1100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a hard porous material - coke. Coke is produced in a coke battery, which is composed of many coke ovens stacked in rows into which coal is loaded.
