CIS Burners

CIS: Combustion Incineration System

Intended use: for burning low quality oils (not usable in any other kind of burner), antifreeze, and disposal of nonflammable liquids. Not intended for burning volatile, explosive vapors producing liquids (i.e., gasoline, alcohol, etc). The CIS system eliminates the problems of clogging and deposits normally encountered in waste oil burner heating systems, because no preheating of the liquids is necessary. However, liquid temperatures ranging from 70°F to 150°F provide the best performance.

How It Works: A fuel oil fired pilot flame (primary fuel / primary flame) is established. Secondary fuel or other liquid is fed by an infinitely variable rate positive displacement metering pump to an aspiration nozzle, atomized by compressed air and sent through the primary pilot flame which vaporizes the liquid. The vapors are thoroughly mixed with primary (burner blower) and secondary (atomizing, compressed air) air and ignited. The ration of primary to secondary fuel can be varied over a wide range, form 1:0 all the way to 1:12 (CIS low range version capacity is 1:7) depending on properties of the secondary fuel and combustion chamber characteristics.

The ratio of primary fuel to noncombustible liquid will depend largely on the incineration temperature required to accomplish a specific result, such as vaporization of plain water or destruction of dioxins, for example.

Conversions/Retrofitting: well suited for conversions because flame size can be manipulated even better than in the high pressure system.
