Abstract: The present invention relates to a spray degasser for removing gas from a liquid, comprising:i) a boiler having at least one sprayer compartment,ii) the sprayer compartment comprises a radial sprayer which is connected to a liquid feed for spraying the liquid for degassing as a spray screen over the liquid present in the boiler,iii) a feed pipe for feeding into the liquid present in the boiler vapour to create in the sprayer compartment a gas containing vapour,iv) an outlet in the sprayer compartment for venting the gas removed from the liquid, andv) an outlet in the boiler for degassed liquid.

Abstract: Vertical radiation tank for gaining heat from process gases.A special performance of the diaphragm pipe walls has been chosen in order to avoid that ash swept along is solidified.

Abstract: A diffuser for finely dividing a liquid, particularly water to be degassed, in which at least two annular plates pairwise engage one another by rims located near the outer circumference and are held spaced apart at the inner circumference by spacers having a radial passage, the space inside the plates of each pair having a connection for the supply of the pressurized liquid to be diffused, at least one of each pair of relatively co-operating plates being resilient and means being provided for clamping the plates together against spring force.
