Boiler Economizers and Waste Heat Recovery

Two solutions exist for recovering the waste heat from boiler flue gases. Conventional economizers preheat boiler make-up or feed water. Condensing economizers recover both latent and sensible heat from the flue gas, and are able to raise boiler efficiencies to over 90%.

How to Generate Steam Energy from Furnace Waste Heat

The furnace in Fig. 1 having a long hearth per se, there is no discrepancy of size between furnace and boiler; but in the case of a smaller furnace, this boiler (a 2-fire-tube boiler, from 8 to 9 m. long) would seriously over-balance the furnace, or else the boiler would have to be shortened, with a considerable diminution of heating-surface.

Cheap way to process waste oil into home heating oil

As a home mechanic, I generate a modest amount of waste oil. Between my vehicles, small-engine equipment, and oil from work I do for others, I suppose I generate 20 gal/year.

As others have said, hot water heating systems are closed loop. The water is returned to the boiler, with little loss. Even with steam radiators, the steam condenses and most of it drains back. There are other places the water can go. You might have a bad toilet valve. Surprisingly, a leaking toilet can be a huge water user, constantly running.
