Electrolink
Traditional approaches to the problem of maintaining air and fuel ratios on modulating burner plants have been based on characterising cams and linkages. Whilst relatively cost effective, they suffer from a number of disadvantages:
-
Time consuming to set up
-
Unwieldy cam and linkage assemblies mounted on the boiler front
-
Eventual wear of the mechanical components, resulting in hysteresis effects
The Electrolink air-fuel mapping processor uses many of the advantages of modern technology to overcome these problems, whilst retaining the ability to interface with traditional as well as future Burner Management Controllers.
Alphalink
