Abstract

The utility model relates to a structure of a combustion type steam generator, the aim of which is to realize a heat conduction structure to provide a steam heating device which can cause combustion heat to be fully absorbed by heat receivers. The utility model is provided with an engine casing, a combustion engine, a combustion chamber, etc., wherein, the combustion chamber of the combustion engine is communicated with a smoke exhausting pipe through a heat conduction pipe in the engine casing. The utility model is characterized in that the heat conduction pipe is a multi-loop heat conduction pipe. The designed multi-loop heat conduction pipe can extend the flow path of heat air flow in the multi-loop heat conduction pipe and greatly increase the heat conduction area.

Description

A kind of multiloop heat pipe steam raising plant

The utility model relates to the structure of combustion-type steam raising plant.

Much lower the thermal efficiency of existing combustion-type steam-heating apparatus, especially steaming (vapour) cabinet etc. is.Reason is the restriction that their steam raising plant is subjected to volume and outward appearance, its heat conduction narrow space, and heat conduction structure wherein loses in simply, the combustion heat of combustor can not fully be absorbed by heated body (water), the combustion heat that is this kind equipment conducts to the heated body except that small part, and major part is to have drained from smoke exhaust pipe.

The purpose of this utility model is: realize a kind of new combustion-type steam-heating apparatus, its heat conduction structure can make the combustion heat fully be absorbed by heated body.

The utility model has casing, combustor and combustion chamber, heat pipe and smoke exhaust pipe, casing is the hollow closed container, have water inlet, steam (vapor) outlet and the smoke evacuation mouth of pipe etc. on it, combustor is contained in outside the casing, the heat pipe of the combustion chamber of combustor in casing is communicated with smoke exhaust pipe, and said heat pipe is the multiloop heat pipe.

The same with many combustion-type steam-heating apparatus, when work, be marked with the water that is used for producing steam in the sealing casing of the present utility model, and heat pipe is not had by water logging; The multiloop heat pipe structure of being conceived, the flow process of thermal current in heat pipe that (combustor) combustion chamber is produced prolongs greatly, and the heat transfer area of heat pipe also greatly increases, and they can allow the water in the casing fully absorb its conduction heat; The decapacitation of multiloop heat pipe structure increases substantially outside the heat conduction efficiency of this kind equipment, and the quantity of steam that the unit interval is produced increases to some extent.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a vertical view of the present utility model.

Fig. 2 is a cutaway view of the present utility model.

Fig. 3 is a cutaway view of the present utility model.Among the figure: 1-steam (vapor) outlet, 2-combustor, 3-water, 4-sewage draining exit, 5-heat pipe, 5-1-pipe bend, 6-combustion chamber, 7-water inlet, 8-water level controller, 9-smoke exhaust pipe, 10-safety valve, 11-casing.

Embodiment: embodiment is made of Fig. 1 Fig. 2 and Fig. 3.

Fig. 1 has provided the vertical view of the steam raising plant that a kind of steamer uses, as shown in Figure 1, two combustors (2) are arranged outside the casing (11), the steam raising plant that this more than one a plurality of combustors dispose, be suitable for the occasion that on-fixed uses especially, as the dining car steamer of train, army's kitchen truck with steamer etc.; Fig. 2 is the A-A view of Fig. 1, and Fig. 3 is the B-B view of Fig. 2.As Fig. 2, shown in Figure 3, the heat pipe (5) that is immersed in the water (3) is a simple circuit, and it forms (as shown in Figure 3) by many parallel heat pipes (5) and pipe bend therebetween (5-1) connection; The multiloop here has isoplanar loop (as shown in Figure 3), and non-isoplanar loop (as shown in Figure 2) can also be arranged.

The multiloop of described heat pipe can be the multilayer loop, and it is formed by a plurality of simple circuits that are parallel to each other, and the simple circuit structure is communicated with by pipe bend (5-1) between each simple circuit as hereinbefore; Described multiloop can also be oblique circuits, and it is intersected to form by simple circuit, is not parallel to each other between each simple circuit and is communicated with by pipe bend (5-1).
