Abstract
The utility model discloses a circulation fluidized bed boiler comprises pouring layer 3, furnace 4, cyclone 5, riser 6, returning charge mechanism 7 and row cinder notch 8 of air inlet 1, water-cooling wall 2, water-cooling wall bottom, and pouring layer 3 lets the pipe position of bending down be down dip 9 at the water-cooling wall, and pouring layer 3 advances to the boiler internal for the upper portion water-cooling wall. Compared with the prior art, the utility model, owing to adopt above structure, make the material that flows down along the water-cooling wall turn to back flow direction furnace, avoided updraft to the local washing away of water-cooling wall to the wearing and tearing that the material produced the water-cooling wall are very slight.
Description
Technical field
The utility model relates to the boiler technology field, particularly relates to a kind of Fluidized Bed Boiler.
Background technology
Present circulating fluidized bed boiler, because of having the structures such as pouring layer, burner hearth, cyclone separator, standpipe and returning charge mechanism of water-cooling wall, water-cooling wall bottom, it is strong to boiler oil adaptability, fuel efficiency is high, high-efficiency desulfurization, discharged nitrous oxides is low and be easy to realize advantage such as ash comprehensive utilization.But because of the top of water-cooling wall bottom pouring layer easily forms boss or depression, this boss or depression easily make mobile material turn to or produce eddy current, and then the water-cooling wall at this position caused heavy wear, so that influence the safe operation of boiler, the performance of restriction sulfuration bed advantage.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of nonabradable circulating fluidized bed boiler is provided.
The utility model is made up of pouring layer, burner hearth, cyclone separator, standpipe, returning charge mechanism and the slag-drip opening of air inlet, water-cooling wall, water-cooling wall bottom, pouring layer allows pipe stoop the position at water-cooling wall to be bottom incline, and pouring layer advances in boiler with respect to the top water-cooling wall.
The utility model compared with prior art is provided with the inclined-plane, makes after the dirty material of water-cooling wall turns to and flow to burner hearth owing to allow pipe stoop the position at water-cooling wall; Pouring layer advances in boiler with respect to the top water-cooling wall, avoided the material in the ascending air to the washing away of water-cooling wall part, so that material is very slight to the wearing and tearing that water-cooling wall produces.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation at a kind of circulating fluidized bed boiler pouring layer shown in Figure 1 position.
The specific embodiment
A kind of circulating fluidized bed boiler as shown in Figure 1, pouring layer 3, burner hearth 4, cyclone separator 5, standpipe 6, returning charge mechanism 7 and slag-drip opening 8 by air inlet 1, water-cooling wall 2, water-cooling wall bottom are formed, described pouring layer 3 allows pipe stoop the position at water-cooling wall to be bottom incline 9, and pouring layer 3 advances 1.5 centimetres to 5 centimetres with respect to the top water-cooling wall in boiler.
