Explosion-proof door structure of oil-fired boiler

Abstract

The invention provides the explosion-proof door structure of the oil-fired boiler, which can effectively reduce the explosion damage in the furnace and play the explosion-proof function of the explosion-proof door. It includes a boiler furnace, which is characterized in that: an explosion-proof door is installed at the tail of the boiler furnace, and an explosion-proof door stop flat steel ring is arranged on the outer end face side of the explosion-proof door, and the explosion-proof door and the explosion-proof door stop flat steel ring Compression springs are installed between them, and the two ends of the compression springs are installed on the outer end surface of the explosion-proof door and the inner end surface of the explosion-proof door stop flat steel ring respectively, and the explosion-proof door has a fire viewing hole.

Description

Technical field [0001] The invention relates to the technical field of industrial boiler structures, in particular to the explosion-proof door structure of an oil-fired boiler. Background technique [0002] Existing oil-fired boilers, especially WNS-type oil-fired boilers, because they are fire tube boilers, their explosion-proof doors cannot be installed in the furnace. In the prior art, the explosion-proof doors are all installed in the flue at the end of the boiler, but if the boiler explodes The situation usually occurs in the furnace, and the flue at the tail of the boiler is far away from the furnace, which easily causes the explosion-proof door to fail its anti-explosion effect, and the explosion damage in the furnace cannot be effectively reduced. Summary of the invention [0003] The invention provides an explosion-proof door structure of an oil-fired boiler, which enables the explosion damage in the furnace to be effectively reduced and plays the role of explosion-proof ...

Problems solved by technology

[0002] Existing oil-fired boilers, especially WNS-type oil-fired boilers, are fire-tube boilers, so their explosion-proof doors cannot be installed in the furnace. In the prior art, the explosion-proof doors are all installed in the tail flue of the boiler. The situation generally occurs in the furnace, and the flue at the tail of the boiler is far away from the furnace, which easily causes the explosion-proof door to fail to achieve its explosion-proof effect, and the explosion damage in the furnace cannot be effectively reduced
