Combined heat and power module produces electricity and hot water from one natural gas fuel source. Self-contained unit includes exhaust gas and coolant heat exchangers, QSK19G PowerCommand[R] controller, and remote monitoring system. It measures 15.1 x 6.5 x 7.9 ft and is offered in 50 and 60 Hz models. Former produces 315 kW electrical energy and 1.58 MBtu/hr thermal energy, and latter produces 334 kW electrical energy and 1.92 MBtu/hr thermal energy.

MINNEAPOLIS - Cummins Power Generation has introduced a new 300 kW combined heat and power (CHP) module that produces electricity and hot water from a single source of fuel (natural gas). The self-contained unit includes a Cummins 300 kW lean-burn gas generator, exhaust gas and coolant heat exchangers, and associated PowerCommand[R] and proprietary remote monitoring system/CHP module controls. Modules are available for either 50 Hz or 60Hz operation.

"The new 300 kW CHP module is ideal for any facility that has a simultaneous need for electricity and hot water for space heating or industrial processing," says Peter Hartzell, Executive Director of Energy Solutions, Cummins Power Generation. "The 300 kW CHP module is particularly suited to facilities such as hotels, health clubs, shopping centers, government buildings or small industrial plants. By creating a virtually complete CHP system in a compact package, Cummins has made it easier for businesses everywhere to get control of energy costs while conserving natural resources."

By using a single source of fuel to produce both electricity and hot water, CHP offers efficiencies that are not attainable by conventional means. CHP reduces overall energy costs up to 35 percent by nearly doubling the efficiency at which heat and electricity are produced.

Each 300 kW CHP module consists of a Cummins QSK19G lean-burn gas generator set coupled with two heat exchangers that recover high-quality heat from the engine coolant jacket and engine exhaust gas stream. The 60 Hz model produces 334 kW of electrical energy and a total of 1.92 MBtu/hr of thermal energy (562 kW thermal) in all heat recovery circuits. The 50 Hz model produces 315 kW of electrical energy and a total of 1.58 MBtu/hr of thermal energy (464 kW thermal) in all heat recovery circuits. The only external accessories required are an exhaust silencer and customer high-temperature and low-temperature process water connections and auxiliary radiators. Inlet and outlet air attenuators are also available, or the unit can be installed into an air ducting system.

The 300 kW CHP module measures 15.1 feet long (4600 mm), 6.5 feet wide (2000 mm) and 7.9 feet high (2400 mm), and is designed for installation in a relatively confined space. An internal fan supplies the required combustion air and ventilation air. The module has a removable canopy that provides sound attenuation to as low as 60 dB(A) measured 3 feet (1 meter) from the unit. The remote monitoring system/CHP module control panel interfaces with the QSK19G PowerCommand controller and allows local control of all the module's systems or remote monitoring and control. Units can be paralleled for greater capacity.
