A steam dispersion system including insulation is disclosed. The steam dispersion system may include a steam dispersion tube with at least one opening defined on an outer surface of the steam dispersion tube and a hollow interior. The insulation covers at least a portion of the steam dispersion tube, the insulation defining an opening aligned with the opening of the steam dispersion tube, wherein the insulation meets 25/50 flame/smoke indexes for UL723/ASTM E-84 and has a thermal conductivity less than about 0.35 Watts/m-K (2.4 in-hr/ft{circumflex over ( )}2 deg F.). A nozzle defining a throughhole may be placed within the opening of the steam dispersion tube, the throughhole being in fluid communication with the hollow interior of the steam dispersion tube to provide a steam exit.

An array of tile assemblies is fixedly connected to a common waterwall panel to form a refractory liner for an incinerator. Each tile assembly includes a unitary, clip-type, metallic anchor, which is directly welded to the waterwall panel, and a solid refractory tile slidably connected to the anchor through a dovetail locking mechanism. The rear surface of the refractory tile includes a longitudinal rib from which projects a dovetail pin configured to receive the anchor. The longitudinal rib increases the overall thickness of the refractory tile through the region of interconnection with the anchor. In this manner, the anchor is suitably protected by the refractory tile from intense heat which may otherwise cause mechanical failure in the locking mechanism. Additionally, the solid construction of refractory tile both limits the presence of air gaps within the tile assembly and reduces the likelihood of tile fragmentation or cracking.

Disclosed is a heat exchange tube of waste heat boiler, which includes a tube body. The outer surface of the tube body is sprayed with a layer of anti-corrosion coating. The components of the anti-corrosion coating are Al.sub.2O.sub.3, CaAl.sub.2O.sub.4 and Ca.sub.3(PO.sub.4).sub.2. On the surface of nano anti-corrosion coating, HF reacts with Al.sub.2O.sub.3, CaAl.sub.2O.sub.4 and Ca.sub.3(PO.sub.4).sub.2 to form AlF.sub.3 and Ca.sub.5(PO.sub.4).sub.3F, which are tightly wrapped on the surface of the coating, thereby effectively preventing HF from corroding the interior of the coating and the heat exchange tube. Meanwhile, due to the anti-corrosion coating with the specific composition of the present disclosure, the heat exchange tube of the present disclosure can be resistant to fluorine corrosion at a high temperature of 600° C. or more, and can be used at a rather high temperature of 1000° C. or more.

Disclosed are an electroplating repair apparatus, an electroplating repair system having the same, and an operating system thereof. The apparatus includes a probe body extending a predefined length in a structure corresponding to an inner diameter part of a tube, an electroplating electrode attached to and surrounding an outer circumferential surface of the probe body, a sealing member attached to opposite end sides of the probe body to seal a target portion to be electroplated, and a solution supply line supplying a solution to the target portion through the inside of the probe body, wherein the apparatus has a structure capable of wholly repairing the inside of the tube including a sealing welding part and an expanded part.

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.
