Maintenance and repair

Maintenance levels CHP ASV 14, 15, 20, 21

The routine inspection, maintenance and possible repairs of ASV-cogeneration plants are designed as a modular system. All components are optimized for 6,000 hours of operation after which a detailed maintenance is required. This means that usually an annual maintenance is required.

The following steps are:

Inspection and maintenance level 1:

every 6.000 operating hours or at least once a year

Inspection and maintenance level 2:

every 12.000 operating hours or every second

If your CHP has less than 6,000 operating hours per year, to ensure service life it is required to carry out an inspection and maintenance once a year. Maintenance level 2 will always be executed in addition to maintenance level 1.

Repair

Certain repair kits for the cogeneration plant must be replaced not by fixed times, but set according to the degree of deterioration. At the ASV-cogeneration plants following repair routines are dependant on the wear and performance:

Repair exhaust gas heat exchanger
Repair engine overhaul

With CHP ASV 40 every 3,000 operating hours or at least once a year, a detailed maintenance is required. The inspection and maintenance level 2 is carried out every 6,000 operating hours or every second maintenance.

Extent of work

At every inspection, the CHP will be reviewed in accordance with optimal defined diagnostic routines.

In addition, basic maintenance work such as renewing the spark plugs. All necessary materials and labour costs other than oil and coolant are included – the disposal of used oil and oil filter is also included. On new spare parts you get 12 months warranty, if it is not subject to wear.

The individual steps can be found in the following table.

Calculation

For a successful application you need the amount of gas/fuel that was consumed in the CHP. If you do not have a separate gas meter for the CHP, you can determine the amount of gas here. The calculation is converted to full- load hours. Thus, the calculated gas consumption is not always above the actual gas consumption.

Some principal customs offices (Hauptzollämter/HZA) are now demanding that the tax-deferred gas is a measurement greater than 15 kWe from the CHP. Please clarify the type of billing in advance to the competent principal customs office (Hauptzollamt/HZA).
