Total Efficiency Concept
Total Efficiency Concept is an innovative method to maximize the overall performance of a combustion process by measuring and controlling the different parameters corresponding to the four most important areas of process operation, which are Combustion Efficiency, Maintenance Efficiency, Safety, and Environmental Efficiency. By balancing all of the requirements set forth in each of these areas, it is possible to operate under conditions that allow for the most cost efficient and safe working environment, while still complying with the environmental regulations applicable to the combustion process.
- Combustion Efficiency
- It is important to strive for perfect combustion efficiency, but many times perfect combustion efficiency is impractical due to the requirements of maintenance efficiency, safety, environmental efficiency, and fuel efficiency.
- Maintenance Efficiency
- Although a brand new burner or boiler may run extremely efficiently with little or no problems, as time goes on, the same boiler slowly begins to lower its efficiency. This is because as a boiler or burner gets older it becomes dirtier and deteriorates. This affects the combustion process greatly and can seriously affect emissions and safety. In most cases, as a burner wears down, more excess air will be needed to ensure proper combustion and reduce CO emissions. To ensure that efficiency is maintained when a boiler ages, it is important to closely monitor the amount of O2 needed to produce proper combustion and CO emissions.
- Safety is a major concern when dealing with any form of combustion. The toxic emissions that are released along with the risk of possible explosions can cause great harm. Older parts that are used in the combustion process can create more dangerous conditions. To ensure complete safety it is essential to monitor levels of CO and CxHy (hydrocarbons). It is also necessary to check the amounts of oxygen needed to ensure low levels of CO and hydrocarbons. CO is a toxic gas that can be lethal in higher concentrations. Hydrocarbons contain unburned fuel, which can cause explosions and consequently, great injury.
- Environmental Efficiency
- Toxic compounds such as sulfur dioxide, carbon monoxide, nitrogen oxides, and particles are undesirable emissions that are frequently results of the combustion of fossil fuels. These compounds cause smog, acid rain, and respiratory problems. In effort to reduce these pollutants federal and state laws have been established under the guidelines of the Clean Air Act and the EPA (Environmental Protection Agency). Combustion analysis aids in monitoring these toxic gases and meeting the regulations set forth by the government and EPA.
