By the vertical type tube derivative forced circulation coal dust combustion hot-water boiler, the problems that the conventional vertical type coal dust boiler has a complex system and much corollary equipment are solved. The vertical type tube derivative forced circulation coal dust combustion hot-water boiler comprises a vertical type hearth water-cooling wall heating surface and a convection flue arranged on the rear side of the vertical type hearth water-cooling wall heating surface, wherein a flame breaking wall is arranged on a rear wall of the upper part of the vertical type hearth water-cooling wall heating surface; a high-temperature economizer, an intermediate-temperature economizer and a low-temperature economizer are arranged in the convection flue sequentially from top to bottom; the upper part of the convection flue is communicated with the upper part of the vertical type hearth water-cooling wall heating surface; and a convection tube bundle passes through the high-temperature economizer, the intermediate-temperature economizer and the low-temperature economizer sequentially from bottom to top. By the vertical type tube derivative forced circulation coal dust combustion hot-water boiler, the problems that the conventional vertical type coal dust boiler has the complex system and much corollary equipment are solved, so the vertical type tube derivative forced circulation coal dust combustion hot-water boiler is suitable for medium-sized industrial boilers.
Description
Technical field
The utility model relates to pulverized coal firing boiler, specifically is a kind of vertical tube formula forced circulation coal dust firing hot-water boiler that spreads out.
Background technology
The coal-burned industrial boiler of knowing at present mainly comprises grate firing boiler and fluidized bed boiler.Wherein, grate firing boiler is meant that certain thickness fuel bed at the boiler that fire grate (or claiming fire grate) upward burns, is also referred to as the grate stove.Fluidized bed boiler is the particle that the raw coal fragmentation is become a certain size, utilizes the Boiling Combustion mode, makes coal in so-called ebullated bed motion and burning, and fluidized bed boiler is also referred to as fluidized-bed combustion boiler.Grate firing boiler technology maturation, shortcoming are that efficiency of combustion is low, and be seriously polluted.The fluidized bed boiler efficiency of combustion is higher, but at present technology is ripe not enough, especially is applied on the Industrial Boiler not too successfully, and the flue gas after-treatment system is complicated, and cost is higher.The pollutant emission of these two big types of boilers all is difficult to satisfy big and medium-sized cities (one, two type of area) governance for reaching standard requirement under present condition.Therefore, the inaccurate coal-burning boiler that uses in urban district is all stipulated in many big and medium-sized cities, only certainly uses fuel oil, gas fired-boiler, and fuel oil, gas fired-boiler be because fuel cost is several times as much as fire coal, and limited to by fuel source, is difficult to large tracts of land and promotes the use of.
Coal dust firing is one of high performance clean burning mode of the coal of generally acknowledging, and its efficiency of combustion can reach more than 91% usually, and stove inner tissue burns simultaneously, and the maintenance task is few.Be that other combustion system institute is unapproachable.Pulverized coal combustion also is the combustion technology of a maturation; On large-sized station boiler, use quite general; And long-term history arranged; Just because the limitation of economic development and science and technology, receive cost height, uncontrollable atmosphere pollution initial ejection concentration and pollute the restriction of aspects such as the thing discharging is serious, make this clean burning technology on the medium-scale industry boiler, not obtain good application for a long time.In order on Industrial Boiler, to use pulverized coal combustion, realize low energy consumption, low emission, researched and developed vertical coal-powder boiler in recent years.The burner hearth of vertical pulverized-coal fired boiler adopts vertical layout, for the vertical furnace chamber that the boiler of other form adopts, increases substantially the efficiency of combustion of boiler, thereby has created advantage for applying of efficient pulverized-coal fired boiler.But vertical pulverized-coal fired boiler still exists system complex, the more shortcoming of corollary equipment, therefore makes the cost of Industrial Boiler be reduced to user's acceptable level as much as possible, remains the target that vertical pulverized-coal fired boiler designing institute is pursued.Based on this, be necessary existing vertical pulverized-coal fired boiler is carried out architecture advances, to solve its system complex, the more problem of corollary equipment.
Summary of the invention
The utility model is in order to solve complicated, the more problem of corollary equipment of existing vertical pulverized-coal fired boiler, and a kind of vertical tube formula forced circulation coal dust firing hot-water boiler that spreads out is provided.
The utility model is to adopt following technical scheme to realize: the vertical tube formula forced circulation coal dust firing hot-water boiler that spreads out comprises the vertical furnace chamber water wall surface, is located at the convection pass of vertical furnace chamber water wall surface rear side; Vertical furnace chamber water wall surface top Hou Qiang is provided with foldede flame wall; High-temperature economizer, middle temperature economizer, low-level (stack-gas) economizer are installed in the convection pass from top to bottom successively; Convection pass top is communicated with vertical furnace chamber water wall surface top; Be furnished with convection bank in the convection pass; Low-level (stack-gas) economizer, middle temperature economizer, high-temperature economizer are passed in convection bank from bottom to top successively, and the convection bank upper end is communicated with vertical furnace chamber water wall surface lower end.
During work; Coal dust is in vertical furnace chamber water wall surface internal combustion; Foldede flame wall can make the flame in the vertical furnace chamber water wall surface once transfer and prolong the burning time of coal dust in the vertical furnace chamber water wall surface, guarantees flame burning time and the coking that prevents coal dust in the vertical furnace chamber water wall surface.Flue gas by vertical furnace chamber water wall surface top after wall flow out, get into convection pass after, wash away high-temperature economizer, middle temperature economizer, low-level (stack-gas) economizer downwards successively, discharge from the convection pass bottom at last.In this process, water gets into low-level (stack-gas) economizer by economizer allocation set case, then via middle temperature economizer; High-temperature economizer; Get into vertical furnace chamber water wall surface lower end through the convection bank upper end then, get into drum by vertical furnace chamber water wall surface upper end at last, accomplish forced circulation.Based on said process; The described vertical tube of the utility model formula forced circulation coal dust firing hot-water boiler that spreads out adopts arrangement form that vertical furnace chamber adds the pedestal convection heating surface and forces the water endless form; Satisfying under the prerequisite of boiler performance; Greatly reduce the height and the steel consumption of boiler, reduced boiler manufacturing cost and boiler room manufacturing cost, solved complicated, the more problem of corollary equipment of existing vertical pulverized-coal fired boiler thus.
The utility model efficiently solves complicated, the more problem of corollary equipment of existing vertical pulverized-coal fired boiler based on existing vertical pulverized-coal fired boiler is carried out architecture advances, is applicable to Industrial Boiler.
