# What is British Gas calorific value?

## What is British Gas calorific value?

Calorific Values by Supplier The current values are British Gas 39.3, EDF 39.1, EON 39.2, ScottishPower 39.0 and SSE 39.6. Gas pricing differs from electricity rates per kwh due to the nature of the fuel source. Calculating electricity bills is as simply as taking a meter reading and multiplying by your unit rate.

### How do you calculate the calorific value of a gas?

How to work it outTake away your last reading from your current reading. This is how many units you’ve used.If you’ve got a metric meter (m3), you can ignore this step. Multiply this number by the calorific value. Multiply this number by 1.02264. Divide this number by 3.6. Multiply this number by the price-per-kWh.

What is calorific value and its unit?

Calorific value is the amount of energy released or produced when 1 kg of fuel burns or any other substance is burnt in the presence of oxygen and the products of combustion are cooled to STP. Its SI unit is kJ/kg.

Does the calorific value of gas change?

Natural gas is metered by volume and its energy content varies with its pressure, temperature and calorific value. The composition of the gas also changes slightly from time to time, which means that the calorific value (energy content per unit mass) will also vary. The CV is reported on invoices.

## Which gas has highest calorific value?

hydrogen

### What is gas calorific value?

Calorific value (CV) is a measure of heating power and is dependent upon the composition of the gas. The CV refers to the amount of energy released when a known volume of gas is completely combusted under specified conditions.

What are the 3 types of fuel?

Fossil fuels principally consist of carbon and hydrogen bonds. There are three types of fossil fuels which can all be used for energy provision; coal, oil and natural gas. Coal is a solid fossil fuel formed over millions of years by decay of land vegetation.

What is calorific value of natural gas?

Heat Values of Various FuelsHeat valueDiesel fuel42-46 MJ/kgCrude oil42-47 MJ/kgLiquefied petroleum gas (LPG)46-51 MJ/kgNatural gas42-55 MJ/kg16

## How is calorific value calculated?

Goutel suggested the following formula from calculating the higher calorific value when the percentage proximate analysis of fuel is known. The formula is, cal. value = 343.3 x fixed carbon % + α x % volatile matter kJ/kg.

### Which fuel has lowest calorific value?

coal

What is high calorific value?

The higher heating value (also known gross calorific value or gross energy) of a fuel is defined as the amount of heat released by a specified quantity (initially at 25°C) once it is combusted and the products have returned to a temperature of 25°C, which takes into account the latent heat of vaporization of water in …

What is the calorific value of water?

Water has absolutely no caloric value. All mammals get calories only from digestible and metabolizable carbohydrates, fats, and proteins (as well as ethanol, for dishonorable mention). In fact water (along with carbon dioxide) is the end product that foods are metabolized to.

## What is calorific value of diesel?

The calorific value of diesel fuel is roughly 45.5 MJ/kg (megajoules per kilogram), slightly lower than petrol which is 45.8 MJ/kg. However, diesel fuel is denser than petrol and contains about 15% more energy by volume (roughly 36.9 MJ/litre compared to 33.7 MJ/litre).

### What is caloric value?

Noun. calorific value (plural calorific values) The amount of energy produced by the complete combustion of a material or fuel. Measured in units of energy per amount of material, e.g. kJ/kg. The amount of energy available from an item of food when digested, mostly from carbohydrates and fats.

What is the formula of water gas?

Water-gas A mixture of carbon monoxide (CO) and hydrogen (H2) produced by passing steam over red-hot coke using the endothermic reaction C + H2O # CO + H2.

Where is water gas used?

Water gas (blue gas, synthesis gas) is a fuel gas used in industrial synthesis of organic chemicals, and in welding, glassmaking, and other high-temperature industrial applications. Water gas is made by passing steam over a bed of hot coal or coke.

## Is water gas a fossil fuel?

A fuel that inspires a lot of wishful thinking. According to the US Energy Information Administration (EIA), “Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the buried remains of plants and animals that lived millions of years ago.”

### What is water gas called?

What is water gas or syngas?

Water gas was usually produced by passing steam over red hot coke. On the other hand syngas is mainly produced industrially by steam reforming of natural gas that involves catalytic decomposition of methane in steam to give the resultant mixture along with the traditional coal gasification and various other methods.

What is blue gas used for?

A gas consisting chiefly of carbon monoxide and hydrogen, formed by the action of steam upon hot coke; used mainly as a source of hydrogen and in synthesis of other chemical compounds. Also known as blue water gas.
