Light boiler wall of steam-injection boiler for oil field

Abstract

The invention relates to a light boiler wall of a steam-injection boiler for an oil field, and belongs to an outer wall of combustion equipment. The light boiler wall is formed by mounting a prefabricated front boiler wall, side boiler walls, a boiler wall top plate, a boiler wall bottom plate and a heat preservation flue on a sledge bottom; the front boiler wall comprises a piece of section steel, an outer guard plate, heat insulation materials and refractory bricks from outside to inside, and a combustor mounting port and a manhole door are arranged on the front boiler wall; the side boiler walls, the boiler wall top plate and the boiler wall bottom plate comprise the section steel, the outer guard plates and the heat insulation materials which are connected sequentially from outside to inside; and the heat preservation flue comprises the section steel, the outer guard plate, the heat insulation materials and an inner guard plate which are connected sequentially from outside to inside. With the adoption ofThrough the improvement, the installation period is shortened, the installation is convenient and fast, and the labor cost is saved during installation; and simultaneously, the light boiler wall has the benefits that load on an offshore production platform is reduced, the limited space of the offshore production platform is saved, and the cost of thermal recovery of heavy oil is reduced.

Description

technical field [0001] The invention belongs to the outer wall of combustion equipment, in particular to a light-duty furnace wall of an oil field steam injection boiler. Background technique [0002] At present, the furnace walls of steam injection boilers at home and abroad mostly adopt heavy-duty furnace wall structures, which are composed of refractory bricks, heat insulation layers, outer guard plates, and reinforcing ribs. If it is applied to steam injection boilers in oilfields on offshore platforms, it will greatly increase the load on the offshore platform. For the offshore platforms built in the early stage of our country, they cannot bear such a large load at all. Therefore, a light furnace wall is needed to meet the needs of steam injection boilers in offshore platform oilfields. Contents of the invention [0003] The present invention aims to overcome the deficiencies of the prior art, and provides a light-duty furnace wall of an oil field steam injection boi...
