Abstract
Description
technical field
[0001] The invention relates to the field of design and manufacture of boilers, in particular to a boiler horizontal radiation section structure, which is suitable for steam injection boilers in oil fields. Background technique
[0002] At present, the steam injection boilers commonly used in oil fields are horizontal, and their radiant sections are generally horizontal cylindrical. In oil field steam injection boilers, in order to increase the tonnage of the boiler and effectively use the boiler space, one method adopted is to change the cylindrical radiation section into a square section; in order to effectively improve the thermal efficiency of the boiler, a membrane wall is used, which can effectively reduce Heat loss due to heat radiation to the insulation between the furnace tubes.
[0003] For the radiant section with a square cross-section, there will be dead zones of flue gas at the four corners, which will cause the furnace tubes at the four corner...
