Fuels - Higher and Lower Calorific Values
The given values are for fuels with the given density. The variation in quality may give heating values within a range 5 -10% higher and lower than the given value. Also the solid fuels will have a similar quality variation for the different classes of fuel. 1 Btu (IT)/lb = 2.3278 MJ/t = 2327.8 J/kg = 0.55598 kcal/kg = 0.000646 kWh/kg.

Steam Heating Process - Load Calculating
In general steam heating is used to change a product or fluid temperature maintain a product or fluid temperature A benefit with steam is the large amount of heat energy that can be transferred. The energy released when steam condenses to water is in the range 2000 - 2250 kJ/kg (depending on the pressure) - compared to water with 80 - 120 kJ/kg (with temperature difference 20 - 30 o C).

Boiler Capacity - Engineering ToolBox
Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)

Electric Resistance Heating | Department of Energy
17/9/2017 · Electric resistance heating is energy efficient in the sense that all the incoming electric energy is converted to heat. However, most electricity is produced from coal, gas, or oil generators that convert only about 30% of the fuel's energy into electricity. Because of electricity generation and transmission losses, electric heat is often

Performing a Combustion Analysis
3/3/2008 · As a safety factor, to ensure complete combustion, appliances are fired with excess air. One of the factors influencing NOx formation in a furnace or boiler is excess air. High excess air levels (>45 percent) may result in increased NOx formation because the excess nitrogen and oxygen in the combustion air entering the flame will combine to form thermal NOx.

Hydrogen Production: Natural Gas Reforming | …
19/8/2020 · Steam-Methane Reforming. Most hydrogen produced today in the United States is made via steam-methane reforming, a mature production process in which high-temperature steam (700°C–1,000°C) is used to produce hydrogen from a methane source, such as natural gas. In steam-methane reforming, methane reacts with steam under 3–25 bar pressure (1

Complete Combustion - an overview | ScienceDirect Topics
For natural gas, an efficient boiler would use about 15 percent excess air, or roughly 19 kg per kg of fuel. Since this is 77 percent by weight N 2, it means that for every kg of fuel, there is nearly 15 kg of N 2 flowing through the boiler, being heated from ambient temperature to combustion temperature, and eventually carrying heat up the stack without bringing any benefit to the process!
