Abstract
The solar preheater (1) lies downstream of the air preheater. Solar preheating units are also installed in both the air and fossil fuel feedlines which are joined upstream of the steam-raiser entry. Thus it is also possible to install a solar preheater in the joined section of the two lines. The solar preheater downstream from the air preheater further heats the combustion air, possibly supplemented by solar preheaters (2,3) in fossil fuel, eg. coal-dust, oil, peat, biomass, etc. and air feedlines. Solar preheating variants include collector tower with receiver and heliostat, trough- or dish-type collectors, a tower having an open receiver or again planar collectors. The amount of fuel infed depends on the degree of preheat produced for the incoming combustion air, so that air raised to maximum combustion heat of 1100 deg.C eliminates the need for fossil fuel altogether. USE/ADVANTAGE - Combustion air heated by the intact flue gas (RAUCHGAS) prevents heat losses en route to steam-raise r, for use in hybrid powerstation in areas precluding total reliance on solar heat.
