Heat Transfer International (HTI) looking to fill Michigan high tech engineering jobs.

HTI Wednesday announced it will create 10 new highly skilled engineering jobs in Michigan.

Based in Caledonia Michigan, the new jobs are intended to add to HTI’s advanced engineering team and supporting the company's Biomass Gasification/Electric Power Generation activities across the globe.

Biomass and Hazardous Waste Gasification is the lifeblood of business success at HTI, and the advanced engineering team we're building here in Michigan will keep us growing," says Dave Prouty, HTI president. "For that reason, we're looking to fill these positions with Michigan's most talented engineering professionals ... highly skilled, enthusiastic individuals who want to be part of this exciting team and help to create the next generation of HTI’s advanced gasification systems."

Since late 2004, HTI has added 14 engineers to its advanced engineering, project management and procurement team. The move to the recently remodeled Caledonia Michigan facility brought together team members from a variety of functions, all working on common projects. The company hopes that co-locating team members from finance, purchasing, manufacturing, information systems and other areas will allow them to work together to make faster, more effective decisions.

Heat Transfer International (HTI) Awarded Contract for Turkey Litter Gasification/Power generation System.

HTI was awarded a contract today to design, manufacture and install a turkey litter gasification system in Howard City, Michigan for Sietsema Farms. Sietsema Farms will collect and deliver the manure (litter) from approximately 1.1 million turkeys to the new HTI gasification plant, where the waste will be converted into heat and electric power. Sietsema Farms will use most of the power and heat for its operations, and will sell the excess power to the grid. The amount of electric power to be generated by the turkey waste is approximately the amount that would be used by 500 homes. The amount of heat generated is roughly equivalent to the power output, which is set at 500KW. The system will be comprised of HTI’s gasification and ceramic heat exchange systems coupled with a Williams hot air turbine. HTI’s gasification system will deliver unrivaled efficiency with higher up time at a lower installed cost than traditional high pressure steam powered systems. The hot air systems are simpler, less costly, easier to maintain, and more efficient than existing steam technology. The system will be the first of its kind in the world.

“Wilcox Devere Energy Solutions” to build biomass gasification plants powered by Heat Transfer International (HTI) patented Biomass Gasification, Waste Heat Boilers and Air Turbine Power generation technology.

Today, HTI announced that the details of the alliance with Wilcox Devere Energy Solution has been finalized. The alliance has developed a system for quickly and simply integrating a combined heat and power generation system for existing and new Bioethanol Refineries. This will allow HTI to focus on their gasification and power generation technologies, by leveraging Wilcox’s plant and systems integration engineering with Devere’s site work implementation and project management capability. The alliance facilitates a simple and easy process for Ethanol Refineries to implement a gasification power and heat generation system. The system is modular, scalable, and can be integrated seamlessly into any existing Ethanol Biorefinery operation. Using locally available biomass feedstocks, the CHP plant can generate power and heat to reduce Biorefining’s dependency on expensive power and natural gas. HTI’s system has the highest efficiency, highest uptime, lowest maintenance, and lowest installed cost of any competitive gasification system. At the heart of the system is HTI’s patented system incorporating a Williams hot air turbine. The gasification combined heat and power generation plant can use any biomass as feedstock. HTI systems currently are gasifying things from simple wood products and crop residues, to hazardous waste such as sewer sludge, military munitions, PCB’s and medical waste.
