Described upper spacer is a sandwich, and the upper end of upper spacer and two ends are communicated with water jacket respectively, and the lower end of upper spacer is fixedly connected with tube seat, and the two ends of described tube seat are fixedly connected with the inwall of housing and be communicated with water jacket.
After adopting technique scheme, this fire grate free boiler adopts the inclined tube of structure uniqueness to support coal, replaces the effect of fire grate, has saved independently fire grate, and structure is simpler; And coal seam, burning zone, ash bed success layering, separately finish and fully give oxygen thoroughly to burn, inclined tube also has the effect of heat conduction simultaneously, help improving the thermal efficiency, the combustion front that is placed on the coal on the inclined tube also tilts, and has increased burning area, can promote the abundant burning of coal; Upper spacer is separated into two combustion chambers with burner hearth, two row's inclined tubes that V-shape is arranged lay respectively in two combustion chambers, the hot gas that coal burning produces is successively by two combustion chambers, not only prolong the route of heat exchange but also can promote the abundant burning of coal, reduce tail gas pollution, reach the purpose of smokeless emission.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of fire grate free boiler described in the utility model comprises housing 1, and housing 1 is a sandwich, and its outward appearance can be square also can make circularly, establishes water jacket in the housing 1, is used to store water.Certainly, Inlet and outlet water is provided with water inlet and delivery port in addition on the outer wall of housing 1 for convenience, and distinguishes mounted valve on water inlet and delivery port.The lower end of housing 1 has cleaning door 2, be used to ventilate or clearing furnace in ashes.The upper end of housing 1 has the mouth 3 of delivering coal, and is used for carrying in burner hearth fuel such as coal.Be provided with upper spacer 4, left transverse tube 5, right transverse tube 6 in the inner chamber of housing 1; Described upper spacer 4 is a sandwich, the inwall of its upper end and rear and front end and housing 1 welds together, be vertically mounted in the inner chamber of housing 1, the upper end of upper spacer 4 and two ends are communicated with water jacket in the housing 1 respectively, the lower end of upper spacer 4 is fixedly connected with tube seat 7, and the two ends of described tube seat 7 are fixedly connected with the inwall of housing 1 and be communicated with water jacket.
Left side transverse tube 5 and right transverse tube 6 are arranged in parallel, and they are also parallel with tube seat 7, and left transverse tube 5 and right transverse tube 6 lay respectively at the left and right sides of upper spacer 4, and as shown in Figure 1, from the section of cutaway view, left transverse tube 5, right transverse tube 6 are arranged in isosceles triangle with tube seat 7.All fixedly connected with the inwall of housing 1 and be communicated with water jacket in the two ends of left side transverse tube 5 and right transverse tube 6, the upper end of described upper spacer 4 is fixedly connected on the inwall at housing 1 top, fixedly connected with the inwall of housing 1 in the both sides of upper spacer 4, the position of upper spacer 4 lower ends is higher than the position of left transverse tube 5 and right transverse tube; Like this, upper spacer 4 two combustion chambers about the burner hearth more than 6 is separated into left transverse tube 5 and right transverse tube.In a combustion chamber mouth 3 of delivering coal is set therein, secondary air mouth 8 and exhaust opening 9 are set in another combustion chamber.
On left transverse tube 5 and right transverse tube 6, be fixedly connected with left inclined tube 51 and right inclined tube 61 respectively, fixedly connected with left transverse tube 5 and connect in the many lower ends with left inclined tube 51 that be arranged in parallel, the upper end of left side inclined tube 51 is extended fixedly connected with the inwall of housing 1 and is communicated with water jacket to the upper left side, fixedly connected with right transverse tube 6 and connect in the many lower ends with right inclined tube 61 that be arranged in parallel, the upper end of right inclined tube 61 is fixedly connected with the inwall of housing 1 and be communicated with water jacket to the upper right side extension.
During use, mouthfuls 3 coal sent into burner hearth by delivering coal, coal is stored in the del space that is surrounded by upper spacer 4, right inclined tube 61 and right transverse tube 6, undermost coal seam width minimum, and past more upper strata, the width in coal seam is big more.The oxygen of sending here from burner hearth bottom during coal burning rises by the slit between the right inclined tube 61, participates in burning; The heat that coal burning produces heats the water in the water jacket by tube seat 7, upper spacer 4, right inclined tube 61 and right transverse tube 6; During coal burning, the culm of nethermost ashes falls to entering grey storehouse and intercepts ventilation between left transverse tube 5 and right transverse tube 6, and the coal on the right inclined tube 61 in top is in high-temp combustion Wang Qu, with fully contact mixed combustion by cleaning door 2 to the oxygen of sending here between the right inclined tube 61 and can not decompose loosening, this moment, uncombusted coal seam, upper strata was in the right inclined tube 61 downslide change positions from the effect lower edge of gravity, automatically add to high temperature Wang Qu burning, and make burning uninterrupted, it is fiercer to burn, help the abundant burning of coal, can avoid because the insufficient energy consumption height that causes of burning, with serious pollution problem; Meanwhile, the tube seat 7 that unburnt part fuel gas is walked around upper spacer 4 lower ends enters in second combustion chamber, and the air of sending here with secondary air mouth 8 mixes, and second-time burning accomplishes fully to burn heat release, and tail gas is discharged by exhaust opening 9.The heat that second-time burning produces passes through, and the water generation heat exchange in upper spacer 4 and left transverse tube 5, left inclined tube 51 and the water jacket reaches the purpose that makes full use of heat energy.
