Jun 01, 2010 · Fig. 4 depicts the heating output-related CO 2 emissions, including all upstream processes for natural gas driven heat pumps, electrically driven heat pumps, electric heating, and oil- and natural gas-fired boilers. For electricity from cogeneration units, it is assumed that the heat from these systems is used within the considered balance
A natural gas boiler further increases the water temperature in case of thermal demand peaks. The electricity and heating demand profiles, the delivery temperature (constant at 80°C), return temperature and DHN water flow rate derive from operational data of a real plant.

Most combustion boilers are fueled by natural gas. Fuel oil, propane, and wood are other fuel sources used in locations where natural gas is not readily available. The hot water for a boiler may also be heated or preheated by a solar thermal water heating system, a ground-source (geothermal) heat pump, or an air-source heat pump.

The thermal efficiency of natural gas boilers is different for different boiler manufacturers. The 30-ton natural gas boiler produced by ZBG Boiler has a thermal efficiency of more than 95%. In summary, the hourly gas consumption of a 30-ton natural gas boiler = 21MW×3600s÷35.53 MJ/Nm³÷0.95≈2200Nm³/h. From this, we came to such a
The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Nuclear fission is also used as a heat source for generating steam. Heat recovery steam generators (HRSGs) use the heat rejected from other processes such as gas turbines.. Solid fuel firing. In order to create optimum burning characteristics of the fire, air needs to be supplied
Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).

The higher the number, the higher the efficiency. EER is used to rate small tonnage air conditioning units, and COP is used to rate heating performance of equipment that use the vapor compression cycle (heat pumps, gas engine-driven chillers, absorption chillers, etc.). Therefore, heat-pumps will generally have both an EER and COP rating.
