microturbine operates at very low emissions and has been designed by Ingersoll-Rand to meet increasingly stringent environmental regulations, such as California's strict emission standards. They also have very few moving parts. This means that a microturbine can operate 24/7 with
little maintenance (typically 8,000 hours or more) before routine maintenance is needed. By supplying continuous on-site power, microturbines reduce a facility's reliance on the public utility. This electricity can be used for peak-shaving as well as dedicated on-site power generation. APPLICATIONS:
Ingersoll-Rand Microturbine Applications:Ingersoll-Rand microturbines can be found in the following locations:
Landfills
The Jamacha Landfill Gas Utilization Project, San Diego County, California use IR microturbines to generate electricity by firing landfill gas (LFG) collected at the site. The methane content of
the LFG is relatively low at a reported 37%. However, this gas is recaptured and used to power four IR 75kw microturbines at the plant. They generate not only electricity for the plant but also hot water needed by commercial customers and nerby residential areas. Ice Rinks
A PowerWorks 70 kW microturbine provides grid-parallel electricity to a 90,000 sq.ft. ice-skating facility in Southern California, containing two ice rinks - one NHL-sized rink for hockey and an Olympic-sized rink. Built-in heat recovery also provides hot water for the desiccant wheels used to dehumidify the facility, which improves ice quality and occupant
comfort. Additionally, hot water is available for ice melting and the ice-resurfacing machine.
Community Centers
A 60,000-square-foot community center and skilled nursing facility located in NY state is using an IR PowerWorks microturbine to provide much of the facility's domestic hot water (DHW) needs. The 70 kW microturbine was installed as a complementary power source to help reduce the center's use of electricity from the public grid. As a result, they are currently saving significant amounts on both electric-utility costs and hot-water energy costs.
Oil Refineries A PowerWorks microturbine is providing electric power and process
heat for American Refinery’s facility in Bradford, PA. The 70 kilowatts of electrical power produced by the generator help to offset the facility's base load, and heat captured from the integrated heat-recovery system preheats the feed water for process boilers. This
highly effective cogeneration application is currently achieving about 70% overall efficiency.
Greenhouses
A commercial greenhouse in Colorado has a rather unique application of the PowerWorks 70 kW microturbine. In addition to providing base-load electricity for the facility, the PowerWorks cogeneration heat-recovery system preheats the water that is used to water plants. Studies have shown that preheating ground water to temperatures around 60F to 70F
(15C to 21C) accelerates the growth of green-house plants (as opposed to using the unheated cold water). The greenhouse consumes at least 90,000 gallons (24,000 liters) of ground water each day, and the PowerWorks microturbine makes a significant contribution in heating the water to
significantly reduce the amount of natural gas used by the boilers.  FAQ’s
Q – How much power is produced by the Ingersoll-Rand PowerWorks microturbine?
A – Currently IR offers a 70kw unit that can easily be placed in parallel. Plans are already under way for the release of a
250kw unit.
Q – How much energy is available from the exhaust heat?
A – The PowerWorks exhaust temperature before cogeneration heat recovery is about 400 deg. F. at a typical mass flow of about 1.4 lbs per second or 1050 cfm. The amount of heat that can be recovered depends upon the application. A typical example would be 307,000 BTU’s per hour, assuming 20 gallons of water per minute with an inlet
temperature of 40 deg. F. Q – Who will provide both the pre-sale service and, more importantly the after-sale support?
A – As with all the products sold by P. C. McKenzie Company, we will support you from the moment you design a system to start-up and beyond. If we sold it, we will service it. Our reputation for after-market support spans over fifty-five years.
