Abstract: The plate heat exchanger and method for manufacturing a plate heat exchanger comprise a stack of heat transfer plates, with first and second flow channels arranged between the plates. Pairs of heat transfer plates form cells. A cell comprises inner spacing elements arranged between the heat transfer plates leaving open a first inlet opening and a first outlet opening for the one of the fluids. The cell also comprises outer spacing elements welded to the heat transfer plates on the sides of the heat transfer plates facing away from each other. The cells are stacked against each other and joined together by welding via the outer spacing elements. The plate heat exchanger further comprises cover plates for covering sides of the stack of heat transfer plates with interruption for an inlet port section formed by the first inlet openings and an outlet port section formed by the first outlet openings.

Abstract: A Combined evaporator and mixer for evaporating a liquid, particularly water, and mixing with a gas, particularly natural gas, including a housing and at least one individual mixing-evaporation module having exhaust gas openings at two of its ends.
