Heat insulation layer of ocean platform thermal oil recovery and steam injection boiler

海洋平台热采油注汽锅炉的保温层

Abstract

本实用新型涉及海洋平台热采油注汽锅炉的保温层。主要解决海洋平台开热采油注汽锅炉的保温问题。其特征在于:所述辐射段炉体的保温层是在炉体的内壁向内依次铺设为2层纤维毯、一层阻气铝箔、在内壁整体铺设陶瓷纤维折叠块,或者在炉体整体喷涂硅酸铝棉;所述对流段箱体内衬的保温层是在对流段箱体的内壁向内依次为两层纤维毡及一层阻气铝箔、然后内壁整体铺设陶瓷纤维折叠块;或者是在对流段箱体的内壁直接整体喷涂硅酸铝棉。该保温结构使得注汽锅炉的热效率、干度、安全环保等经济技术指标均高于陆上锅炉现有指标。
The utility model relates to a heat insulation layer of an ocean platform thermal oil recovery steam injection boiler, which mainly resolves the problem of heat insulation of ocean platform thermal oil recovery steam injection boiler. The heat insulation layer is characterized in that the heat insulation layer of a radiation-section boiler body is formed by steps including that two layers of fiber blankets and a layer of gas-barrier aluminum foil are inwards successively laid on the inner wall of the boiler body, and a ceramic fiber folding block is integrally laid on the inner wall, or aluminum silicate cotton is integrally sprayed on the boiler body; and the heat insulation layer lined in a convection-section box body is formed by steps including that two layers of fibrofelt and a layer of gas-barrier aluminum foil are inwards successively disposed on the inner wall of the convection-section box body, and then a ceramic fiber folding block is integrally laid on the inner wall, or aluminum silicate cotton is integrally sprayed on the inner wall of the convection-section box body. The heat insulation layer of an ocean platform thermal oil recovery steam injection boiler leads economic and technical targets such as thermal efficiency, dryness, safety, environmental protection and the like of the steam injection boiler to be higher than the existing targets of a land boiler.
