Operating your boiler with an optimum amount of excess air will minimize heat loss up the stack and improve combustion efficiency. Combustion efficiency is a measure of how effectively the heat content of a fuel is transferred into usable heat. The stack temperature and flue gas Oxygen (or Carbon Dioxide) concentrations are primary indicators of combustion efficiency.

Natural Resources and Office of Energy Efficiency
Typically, reducing O2 in the flue gas by 1 percent- for example, from 5 percent to 4 percent- increases boiler efficiency by about 2.5 percent.

Controlling excess air is the most important tool for managing the energy efficiency and atmospheric emissions of a boiler system.

As graph shows, the effect of air temperature on excess air in the flue gas can be dramatic.


Carbon Credits

Carbon credits are tradable unit scheme. They provide a way to reduce greenhouse gas emissions by giving them a monetary value.

A credit gives the owner the right to emit one tone of Carbon dioxide.

International treaties such as the Kyoto Protocol set Quotas on the amount of greenhouse gases countries can produce. Countries, in turn, set quotas on the emissions of businesses.

Businesses that are over their quotas must buy carbon credits for their excess emissions, while businesses that are below their quotas can sell their remaining credits.

Credits can be exchanged between businesses or bought and sold in international markets at the prevailing market price.

The concept of carbon credits came into existence as a result of increasing awareness of the need for pollution control. It was formalized in the Kyoto Protocol an international agreement between 141 countries. Carbon credits are certificates awarded to countries that are successful in reducing the emissions that cause global warming.

For trading purpose, one credit is considered equivalent to one tone of CO2 emissions. Such a credit can be sold in the international market at the prevailing market price.

Countries with surplus credits can sell them to countries with qualified emission limitation and reduction commitments under the Kyoto Protocol.

By way of example, assume a small industry produces 100,000 tones of greenhouse emissions in a year. The government then enacts a law that limits then maximum emissions a business can have.

So the industry is given a quota of say 80,000 tones.

The industry either reduces its emissions to 80,000 tones or its require to purchase carbon credits to offset the excess.

As emission levels are predicated to keep rising over time, it is envisaged that the number of companies wanting/needing to buy more credits will increase hence pushing the market price up, and hence encouraging more groups to undertake environmentally friendly activities which create for them carbon credits to sell. At the moment, the Carbon market is quoting one carbon unit is worth US$ 10 to $30.
