Claim 17:
18. A membrane panel for a heating incineration installation,
wherein a material of the panel is selected from steel alloys, comprising 0.02-3 wt. % C, and at least one further metal selected from Mb, Mn, B, Ti, V, Nb, Cr, Al, Cu, Si, Co, W, and Ni, in an amount of total further metal of 0-10 wt. %,
wherein the membrane is adapted to operate at a pressure from 3*103 kPa-3*104 kPa and at a temperature of 850-1650 K,
wherein the membrane panel comprises at least one tube, and a NiCr alloy cladding, wherein the NiCr alloy comprises >35 atom % Ni, >18 atom % Cr, 0-6 atom % Fe, <19 atom % Mo, 0.1-5 atom % Nb+Ta, and 0-10 atom % of at least one of C, Mn, Si, P, S, Al, Ti, W, Cu, and Co,
wherein the cladding has a surface roughness Ra of <60 μm, a surface purity SA of ≥2.0, and a thickness of 1.5-10 mm over at least 50% of the cladded area.
