Heat Recovery Applications - Matthews Environmental Solutions

Heat is recovered indirectly from the incinerator exhaust gases by passing them through a gas tube heat exchanger. Cool ambient air is blown across the hot heat exchanger tubes, which provides heated clean air for factory space heating, pre-heated combustion air or process drying. For more information, view the technical information document.

Industrial Waste-Heat Recovery: Benefits and Recent

Although some industrial sectors may offer greater opportunities for waste-heat recovery than others, most industrial sectors can reuse waste heat for preheating combustion air, preheating boiler feedwater, and preheating process load. For example, gas-to-gas heat exchangers can transfer heat from hot exhaust gases to the incoming combustion air.

How to Destroy a Boiler -- Part 1

A gas/oil boiler has no inventory or bed of fuel. When you trip the burner, for all practical purposes, the heat input immediately stops. With solid fuel units, however, a fairly large mass of bark, coal, etc., is still on the grate and even though starved of air by the loss of the forced draft fan, these units have more "thermal inertia" and
