Conversion Equations #2 OiI: NaturaI Gas:

ppm = (Ib/MMBtu) *1290 ppm= (Ib/MMBtu) *1370 Ib/MMBtu = (ppm)/1290 Ib/MMBtu = (ppm)/1370

ppm = (Ib/MMBtu) *1260 ppm - (Ib/MMBtu) *1340 Ib/MMBtu = (ppm)/1260 Ib/MMBtu = (ppm)/1340

Conversion data is provided for ppm and lbm/MMBtu. Values in these curves are based on dry analysis of boiler operation 15% excess air. Conversion curves and equations are provided for natural gas, propane, and fuel oil.

Renewable Energy 101

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
