Abstract
The utility model relates to a shell type internal circulation fluidezed-bed boiler which is composed of fluidezed-bed combustion and a boiler chamber, a high-temperature gas and solid separator, a smoke pipe, etc., wherein, the smoke pipe is used as a convection heating surface. The utility model is characterized in that the circumference of the boiler chamber is composed of a cylindrical boiler furnace which is used for bearing the external pressure of working media, the furnace chamber, the high-temperature gas and solid separator, and the smoke pipe are respectively arranged in different shells which are connected through gas connecting pipes and water connecting pipes, and the shells are connected through pipes by air, dust particles, and flue gas. The utility model is a split shell type internal circulation fluidezed-bed boiler which can be used for reinforcing combustion and heat exchange, decreasing the abrasion of heated surfaces, and realizing the quick fix.
Description
The utility model belongs to the Industrial Boiler Technology field, refers in particular to the pan shell type internal circulating fluidized-bed boiler.
In the prior art, the Industrial Boiler burner hearth is made up of water pipe, the burner hearth cross section is a square, the water pipe outer surface is a convection heating surface, used high-temperature separator make by refractory material or refractory material in the middle of the lining play cooling effect with water pipe or steam pipe, burner hearth circumference, convection heating surface circumference, high-temperature separator outer wall have all been built thick and heavy furnace wall.
Above-mentioned prior art exists following defective: 1, the burner hearth of being made up of water pipe, circumference is discontinuous, and is easy to wear.2, square burner hearth, heating surface is inhomogeneous, easily causes the water circulation problem of water screen tube.The square burner hearth is unfavorable for the circulation of gas-solid mixture in the stove, and causes wear problem.3, contain grey airflow scouring festoon and cause serious wear problem.4, thick and heavy furnace wall and insulation high-abrasive material cause the thermal inertia that boiler is very big.When boiler startup running and variable load operation, response speed is very slow.5, the water-tube boiler steel quantity consumption is big, and the manufacturing cost height is bulky, is not suitable for making small-sized CFBB.6, boiler is generally the negative pressure operation, is unfavorable for burning, heat exchange, desulfurization, denitration.
Chinese patent discloses a kind of " pressurized internal circulating fluidized-bed boiler " (94102536 that is used for the hybrid power generation system, substantive examination), comprise a pressure vessel, one is located at a burner hearth and the main fluidized-bed combustion chamber of being with air-diffuser in the pressure vessel, one energy recovery chamber separates with an inclination partition wall and main chamber, one is fluidized the energy recovery chamber that main chamber was sent into and sent to medium, one free space is integrally formed in main chamber and top, energy recovery chamber, and the flue gas of discharging from the energy recovery chamber of main chamber is mixed this space.But this design only is used for electricity generation system.
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of pan shell type internal circulating fluidized-bed boiler is provided, and its energy overheavy firing and heat exchange reduces the wearing and tearing of heating surface, and volume is little, can realize fast-assemblingization.
For achieving the above object, the solution that the utility model is taked is: a kind of pan shell type internal circulating fluidized-bed boiler, form by shell, fluidized bed combustion equipment and burner hearth, High Temperature Gas solid separator, smoke pipe etc., smoke pipe is as convection heating surface, it is characterized in that: the circumference of burner hearth is made of the cylindrical shape flue that bears the working medium external pressure, burner hearth, High Temperature Gas solid separator, smoke pipe are arranged in respectively in the different shells, link to each other with vapour connecting leg, water connecting leg between the shell, air, grey particle, flue gas also link to each other shell by pipeline.
In the utility model, burner hearth, High Temperature Gas solid separator and smoke pipe all obtain water cooling in different shells, and the high temperature gas-solid separates in the High Temperature Gas solid separator through flue, contains grey air-flow and make parallel baffled in smoke pipe.It compared with prior art has following good effect: 1, the burner hearth of circular cross-section, help heat exchange in the stove, and help the circulation of in-furnace dust particle, help containing grey air-flow by certain requirement rotation.2, be easy to realize pressurized firing, overheavy firing and heat exchange improve the effect of desulfurization, denitration.3, rule, smooth is easily made on flue, smoke pipe surface, can reduce the wearing and tearing of heating surface.4, do not have heavy furnace wall and insulation high-abrasive material, can reduce the thermal inertia of boiler, realize starting fast.5, compact conformation, volume is little, easily realizes fast-assemblingization.
The utility model will be further described below in conjunction with embodiment and accompanying drawing thereof.
Accompanying drawing is the schematic diagram of present embodiment, and A is the soot particle loopback among the figure, and B is for containing grey air-flow, and C is a clean gas flow.
As shown in drawings, a kind of pan shell type internal circulating fluidized-bed boiler, by shell (1-1,1-2,1-3), fluidized bed combustion equipment and burner hearth, High Temperature Gas solid separator (3), smoke pipe compositions such as (4), smoke pipe (4) is characterized in that as convection heating surface: the circumference of burner hearth is made of the cylindrical shape flue (2) that bears the working medium external pressure, burner hearth, High Temperature Gas solid separator (3), smoke pipe (4) is arranged in different shell (1-1 respectively, 1-2,1-3) in, different shells (1-1,1-2,1-3) between with the vapour connecting leg, the water connecting leg links to each other, air, grey particle, flue gas also links to each other shell (1-1,1-2,1-3) by pipeline.
The utility model is a kind of split pan shell type internal circulating fluidized-bed boiler.
