Technical Summary: Influence of Chemical Kinetics and Turbulence on Combustion Emissions
Dan Wallace Chemical kinetics and turbulence play critical roles in the formation and control of combustion emissions. Understanding their influence is essential for optimizing combustion processes and minimizing harmful pollutants. Here is a technical summary of how chemical kinetics and turbulence affect combustion emissions: Chemical Kinetics: Chemical kinetics refers to the study of chemical reactions and their rates. […]
PREFERRD’S SUSTAINABLE SOLUTIONS FOR HYDROGEN & SPECIAL FUELS
Because of its instability, hydrogen is “blended” with natural gas and used as a “green” fuel, usually in large industrial applications that have excess Hydrogen on hand or are making a targeted move toward lowering of emissions and meeting environmental regulations. The blending process is delicate and yet is essential in keeping steady combustion and avoiding expensive outages. […]

How to make “Green Hydrogen” a Viable Solution for Reducing Emissions?
To move forward with plans for development in the face of the volatility of shared natural resources, many industries are taking a closer look at alternative fuels. Hydrogen, in particular, has amassed significant attention. “Green hydrogen” is a fuel created using renewable energy, and it has proven to be a valuable asset in transportation, manufacturing, and other energy-focused […]
Boiler System 101: The Advantages of Full System Integration
Danbury, CT – A boiler system functions as a critical component to the continuous operation of a facility. It is important to maintain safe, reliable, and efficient operation while minimizing any downtime of the boiler system to prevent disruption of operation and significant loss. A boiler system consists of many sub-systems working in harmony – the boiler, the burner and its controls, boiler […]
Automatic, Variable Ratio, Firing of a Blend of “Free” and Purchased Fuels
-Peter Lavelle, Danbury CT “Free” fuels are available from many processes: Digester Gas from wastewater treatment plants, Bio-Gas from agricultural and food processing plant waste, Hydrogen from chemical plants, Off-Gases from a Refinery, etc. The Challenge Firing these “free” fuels in a boiler, process heater, or engine-generator significantly reduces operating costs and can significantly reduce greenhouse gas emissions. […]
