During thermal processing of dictyonema argillite in the solid heat carrier unit most of feed-stock sulfur (more than 70%) is transferred to the stack gas
, and the content of total sulfur in the solid ash residue of dictyonema argillite is low (containing 10-20% of total sulfur).
The company also noted good sales of stack gas
analyzers in Japan.
Priced at $99 in any quantity for OEMs, the Model 265 Series transducers are suitable for static pressure and air velocity control, fan tracking, cleanroom and isolation ward pressurization, terminal box and environmental pollution control, stack gas
monitoring, furnace control, and medical instrumentation applications.
At a 660-ton project in Indiana, Evotherm achieved substantial reductions, compared to the hot mix control, in stack gas
emissions: nitrous oxides, total particulate matter, total organic matter, and benzene soluble matter, said Everett Crews, a technical manager for MeadWestvaco/Asphalt Innovations, speaking at World of Asphalt.
Some of the water is evaporated into the air stream, with the heat required for the humidification operation being recovered from the intercooler and the stack gas
by circulating water leaving the humidifier.
"For one, if you dry the stack gas
, it actually becomes easier to capture the suite of contaminants involved in coal firing....
Gas and steam applications include stack gas
flow monitoring, flare digester gas measurement, and natural gas.
The Testo 325-i analyzer offers pushbutton operation that delivers stack gas
measurements within 60 seconds.
sampling was done by Southwestern Laboratories, Houston.
A range of sizes of atomizers for stack gas
cleaning were designed and field tested.
With a thermal oxidizer, a facility may need different types of gas analyzers, such as stack gas
analyzers, to prove the combustion is efficient and not running too rich.
