There have been some useful discussions at recent MCPD workshops regarding treatment of mobile boilers under MCPD; here we are referring to steam and hot water boilers that are in containers on the back of lorries that can be transported from site to site very easily. Some of the comments we make here for boilers will be useful for diesel generators as well – the market for standby gensets is even larger than for boilers, and the timescales are often much reduced, the gensets just being installed to support an event or supply a village whilst a cable fault is repaired.
