How to Lower Power Plant Emissions – some suggestions

Here are my simple suggestions on how to lower power plant emissions and address global warming and climate change issues.

—————-

Hi Jeff,

I am not an environmental scientist, but this I can say.

As long as your liquid fuel has lower than 1% Sulfur by weight, you will not exceed SO2 concentration (in volume % or parts per million by volume or as mg/Nm3 or milligram per normal cubic meter) required by the EPA (usually given in ppm and mg/Nm3 for both old and new power plants).

Having sufficient excess air (3-15% or average of 9%) will help eliminate unburnt fuel emission such as CO (carbon monoxide) and THC (total hydro carbon) as well as unburnt carbon (C) particles.

You also need to lower impurities such as ash to reduce total suspended solids (TSP) emissions (ash and unburnt carbon fuel).

To lower NOx emissions, the firing of oil must be done in stages so that the flame is not too hot that it will dissociate nitrogen (N2) in the air into oxides of nitrogen (NOx) that contributes to acid rain together with oxides of sulfur (SOx).

But this days, you have to address global warming and climate change issues by lowering your carbon (C) or as carbon dioxide (CO2) emissions.  This means keeping the fuel to electricity conversion efficiency (thermal efficiency) as high as possible, which is typically around 33-36% for oil thermal power plants based on the steam Rankin cycle.  To lower the carbon footprint, you need to move away from the simple steam Rankin cycle to combined cycles (CCGT) to raise efficiency to over 54-59%, almost double, thus reducing the carbon footprint by almost half.

Hope I was of help,

Marcial

For the readers who would want to design a power plant that addresses global warming and climate change issues, energy efficiency considerations,  cost of power plant and resulting electricity tariff, please email me your concerns as I may provide you a good feasibility study that addresses all the above issues.

Cheers,

Marcial, your energy technology expert (for conventional, nuclear and renewable energy power generation).

Avoiding Widespread Flooding Thru Predictive Dam Water Release Modeling – Recent Nigeria, Pakistan and Philippine flooding

Avoiding Widespread Flooding Thru Predictive Dam Water Release Modeling – Recent Nigeria, Pakistan and Philippine flooding

The very recent Nigeria flooding that affected over  2 million people and the continuing widespread misery due to flooding in Pakistan is a portent warning of serious effects of global warming and unabated release of Green House Gas (GHG) emissions of CO2 and other similar gases such as methane (21 times of equivalent CO2).

This increasing severity of weather changes from widespread flooding to severe drought has indeed impacted on the daily lives of peoples, especially the poor whose makeshift houses along dangerous and hazardous terrain and communities are subject to more frequent dislocations and damage to property as well as loss of lives, which is magnified by the lack of adequate planning (such as doing predictive dam water release simulation), preparations (pre-positioning of emergency safety and rescue equipment), and lack of maintenance of flood control infrastructures such as dams, dikes, levies and embankment supports that separates the flood plains from low-lying communities.

Indeed, the lack of foresight (pre-emptive release of dam water) to avoid catastrophic release later at the height of a storm as what happened in the Pangasinan-Agno River system in the Philippines and the continuing saga in Pakistan is just another grim reminder of the need to use advanced computing technology (dam simulation logic and a Excel spreadsheet) to avoid the tragic consequences of damaged levees, embankments as a result of high releases of impounded water.
