How to calculate NOx emission factor?

Usually, you can assume full year operation for emission calculation purposes (8760 hours per year.) So, the unit burns 0.05 tons of waste per hour. Multiply this by the emission factor of 3 lb NOx per ton of waste. 0.05 ton/hr x 3 lb/ton = 0.15 lb NOx/hr.

How is fuel factor calculated?

fo = (20.9 – %O2)/%CO2, Where %O2 is the percent O2 by volume, dry basis, %CO2 is the percent CO2 by volume, dry basis, and 20.9 is the percent O2 by volume in ambient air.

What does mmbtu HR mean?

Millions of British Thermal Units per hour
MMBTU/hr (HHV) means a unit of measure of heat input rate expressed as Millions of British Thermal Units per hour, based on the higher heating value of the fuel.

How do you calculate total emissions?

Calculate the actual emissions by multiplying the emission factor by the actual annual production rate or material usage rate (or whatever units the emission factor is in), and dividing by 2000 pounds per ton.

How is engine emission calculated?

Calculate actual emissions using one of the following methods: If the emission factor is in units of pounds per quantity of fuel (gallons or cubic feet): Actual emissions (tpy) = Emission Factor (lb/unit) x Actual Annual Fuel Use (unit) x ([100 – Control Efficiency] ÷ 100)

How do you calculate the heat value of natural gas?

The price is not set by the quantity of natural gas, but the quality and the heating value will determine how much an individual (or a country) will pay for this fuel. The formula is simple: Price of 1 m3 natural gas = volume (m3) x heat value (MJ/m3) x price (Currency/MJ) x VAT.

What is K factor in oil and gas?

The k factor is a calculation that shows how quickly a home is consuming the fuel it uses to produce heat. The k-factor calculation can be used in homes that use all types of combustible fuel, from natural gas to propane to heating oil. A home’s k factor represents the number of gallons of fuel burned per degree day.

How many MMBtu are in a BTU?

MMBtu↔Btu 1 MMBtu = 1000000 Btu.

How is CO2 emissions calculated?

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). 0.1 mmbtu equals one therm (EIA 2019).

How do you measure CO2 emissions?

By measuring its presence or absence in a particular parcel of air, researchers can track down how much CO2 in that air came from natural biogenic sources and how much from burning fossil fuels. And if the parcels are carefully chosen, that analysis can pinpoint the sources of emissions.

How do you measure air emissions?

The Short Answer: Air quality is measured with the Air Quality Index, or AQI. The AQI works like a thermometer that runs from 0 to 500 degrees. However, instead of showing changes in the temperature, the AQI is a way of showing changes in the amount of pollution in the air.

What is the Btu value of natural gas?

In 2020, the U.S. annual average heat content of natural gas delivered to consumers was about 1,037 Btu per cubic foot. Therefore, 100 cubic feet (Ccf) of natural gas equals 103,700 Btu, or 1.037 therms.

How is heat value calculated?

The specific heat capacity is the heat or energy required to change one unit mass of a substance of a constant volume by 1 °C. The formula is Cv = Q / (ΔT ⨉ m) .

How do K factors work?

The K-Factor is simply how many degree days it takes for your customer to burn ONE gallon of fuel. So if I have a 500 gallon propane tank at my customers house and they have a 6.5 K-Factor, they are going to burn one gallon of propane for every 6.5 degree days.

Is K factor related to time?

K -factor is described as a function of time moments and the normalized level of the power of the signal envelope.
