Abstract
The utility model relates to a boiler, in particular to a positive pressure door of an oil field steam injection boiler, which comprises a rear end plate of the boiler fixed on the boiler or a door sleeve at the inner side of a front end plate of a burner and an inspection door arranged in the door sleeve; the center of the outside of the inspection door is fixed with an observation hole; the inside of the inspection door is provided with an a channel through which a boiler cavity can be observed through the observation hole; the outer side of the end of the inspection door contacted with the boiler cavity is provided with a firestop brick; and the inside of the firestop brick is provided with a b channel matched with the a channel inside the inspection door. The positive pressure door with a firestop structure can be adopted under the condition without requiring cooling air for reducing the appearance temperature of the positive pressure door, reducing heat radiating loss, prolonging the service life of the glass of the observation hole under the condition of not influencing the fire observation, and the positive pressure door is simple to repair.
Description
Technical field
The utility model relates to a kind of boiler, specifically is a kind of fire door of uphole steam generator.
Background technology
Uphole steam generator commonly used now all adopts pressure-fired chamber combustion form, for observing flame profile and maintenance convenience in the injection boiler radiant section, the malleation fire door of band peephole is installed on the front end-plate at the stove end plate of boiler or burner place, the installation region flue-gas temperature is between 950 ℃ to 1200 ℃, because flue-gas temperature is high and be in slight positive pressure state, malleation fire door now commonly used mostly adopt do not establish cooling air can disposablely remove overall structure, be disposable the removing of energy, so do to such an extent that relatively lightly also directly be subjected to Fire Radiation, appearance temperature height often occurs, radiation loss is serious, peephole glass cracky, problems such as maintenance difficult.
Summary of the invention
The technical problems to be solved in the utility model is that the deficiency at prior art exists provides a kind of uphole steam generator malleation fire door, not establishing cooling air and not influencing reduction malleation fire door appearance temperature under the situation of seeing fire, prolongs the peephole glass life-span.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is, uphole steam generator malleation fire door comprises the fire door overcoat of the stove end plate that is fixed on boiler or burner front end-plate inboard and places inspection door in the fire door overcoat, a peephole is fixed by the outside central authorities of inspection door, inspection door inside is provided with a passage that can observe furnace chamber by peephole, the described inspection door and the furnace chamber contact jaw outside are provided with the retaining firebrick, and described retaining firebrick inside is provided with and the corresponding b passage of the inner a passage of described inspection door.
Below the utility model made further specify.
Further, the inner fill insulant material of described inspection door.
Further, be provided with anti-backstop firebrick at described retaining firebrick near furnace chamber one side and fall into barricade in the stove.
Further, described inspection door is fixed on described fire door by latch and bearing pin and puts outward, and is provided with sealing gasket at the place, fixed position.
Further, described malleation fire door is square or circular configuration.
Design principle of the present utility model is, when uphole steam generator moves, high-temperature flue gas projects in the most of retaining firebrick reflection of being made of refractory material of radiant heat on the malleation fire door melted down, and the heat that is delivered to inspection door is reduced significantly, and fire door appearance temperature is reduced.Center at the retaining firebrick is provided with a passage, observes flame in the injection boiler radiant section with convenient from peephole.
Need personnel to enter when overhauling in the stove after the blowing out, open the malleation fire door and divide three steps to finish:
The first step: unclamp latch and bearing pin and take away;
Second step: the inspection door that has peephole is taken out in the fire door overcoat;
The 3rd step: the retaining firebrick is taken out in the fire door overcoat.
Opposite when closing fire door with above-mentioned steps.
As known from the above, the beneficial effects of the utility model are: under the situation that does not need cooling air, adopt the malleation fire door with retaining firebrick structure not influencing reduction malleation fire door appearance temperature under the situation of seeing fire, reduce radiation loss, prolonging the peephole glass life-span and easy to maintenance.
