Abstract
The present invention is in the field of a high pressure heating installation and in particular a waste incineration installation comprising an advanced panel design and cladding thereof. Said cladding relates to a cladding to a in particular at least partly curved surface of a membrane panel, which panel is used in a high temperature and high pressure incinerator, such as a waste incinerator.
Claims21
A High pressure and high efficient heating installation comprising at least one membrane panel,
- wherein a material of the panel is selected from steel alloys, comprising 0.002-3 wt. % C, and at least one metal selected from Mo, Mn, B, Ti, V, Nb, Cr, Al, Cu, Si, Co, W, and, Ni, in an amount of total metal of 0-10 wt. %,
- wherein the installation is adapted to operate at a water-steam pressure from 3*103 kPa-3*104 kPa and at a flue gas 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 at least one of a surface roughness Ra of <60 μm as determined according to DIN 25410, a surface purity SA of ≥2.0 as determined according to ISO 8501-1, and a thickness of 1.5-10 mm over at least 50% of the cladded area as determined according with a Fischer Deltascope FMP 10, head FJB2.
