AirCHP is a unique form of small-scale CHP, which directly heats air by using the latent and generated heat from the power generation CHP package.
How does AirCHP work?
The technology used is similar to that of modular packaged CHP plant, but the equipment packaged includes the heated air stream as well as integral heat exchangers and air handling equipment. At peak performance, the AirCHP system can achieve 95% efficiency. Suitable applications include distribution warehouses, process drying applications, space heating, and other applications where hot air is required on a continued basis.
The prime movers used by AirCHP in most applications are reciprocating natural gas or fuel oil engines. This approach ensures the high efficiency of energy conversion and improved flexibility by displacing a number of separate items of the plant. The range of AirCHP systems give electrical output up to 2MW per unit, together with air heat output up to 2.5MW (thermal) and water heat output up to 2MW (thermal).
What about installation?
A typical AirCHP installation consists of one or more units located either inside or outside. The AirCHP system provides electricity to the site distribution system and heated air for the conditioned space. Few buildings require only air heat therefore the package is designed to convert a proportion of the waste heat to hot water. Cooling can also be provided through the use of close-coupled absorption chillers, giving a totally flexible and highly energy efficient air conditioning package.
An enhanced level of site power security can be reached when provided in conjunction with the CHP Power Delivery Control (PDC) system.
Industrial AirCHP
AirCHP can be used for a variety of industrial processes, because it provides electricity generation with air heat recovery.
Custom Design, Custom Features
Industrial AirCHP is custom designed for each individual application, from providing pre-heated air to industrial burners, hot air supply to drying processes and process air conditioning.
Industrial AirCHP is supplied as a packaged unit. All available heat from the engine surfaces, intercooler, jacket water cooling circuit, and exhaust gas is used. The system is designed to provide air continually to the process at the required flow, temperature, and quality.
Gas engine-driven industrial AirCHP reaches a maximum temperature of 120°C (248°F) as an indirect system and 150°C (302°F) as a direct heating system. Additional gas can be burned in the 02-rich air-stream to introduce higher air temperatures into the process.
