SOOT BLOWER PREPARING FOR OUTAGES
When boilers are subjected to extended outages, as in heating plants maintenance can e reduced by giving proper attention to the equipment before and during the down period.
- Moving cams should be well coated with rust preventive lubricants.
- Mechanical units should be covered with canvas, oil cloth or paper for protection against moisture or excessive dust.
- If operating valves or pistons have rings or parts not made of rust resistant alloys these parts should be removed. They can be protected by a rust inhibitor.
- When feed lines or telescope tubes are of carbon steel, the units should be extended and rust preventive applied to these parts.
- Inspections and repairs should be made immediately when the boiler is shutdown to assure proper operation when the boiler is put back into service.
- Care, adjustment and maintenance of automatic control, panels for automatic sequential systems are properly entrusted to the instrument personnel. Such systems usually require little care after being placed in service, except to keep all parts thoroughly clean.
- Generally speaking, they require the same maintenance as nay industrial control system except that the loads on relays, indicator lamps and switches are comparatively light, therefore, requiring less attention. Little maintenance trouble is met, if this equipment is kept clean and free dust and oil.
