Abstract

The utility model discloses a high-efficiency non-pressure civil boiler, comprising a shell body, a water jacket and a boiler hearth from the exterior to the interior. The inner wall of the boiler hearth is connected with two U-shaped plates at least which extend to the inclined lower direction. The U-shaped plates are in alternate arrangement up and down. The interior of the U-shaped plate is provided with water, and is communicated with the water jacket. The U-shaped plate on the bottommost plate extends out from the inner wall of one side to the inclined lower direction, and extends to the inner wall of the other side to be connected, and the U-shaped plate is provided with a smoke outlet at least. The upper part of the boiler hearth facing the chimney is provided with a thick heat exchanger pipe whose diameter is larger than the diameter of a chimney. The lower part of an ash chamber is provided with a heating water jacket. The heat energy of the utility model is fully collected, the heat efficiency is high, the exhausted harmful gas is less, and the environment pollution is lightened.

Description

The efficient non-pressure civil boiler

The utility model relates to a kind of vertical nothing and presses civil boiler.

Present vertical nothing is pressed civil boiler, the cigarette in the burner hearth, the straight-through chimney of fire, and energy acquisition is insufficient, and the thermal efficiency is lower, and furnace bottom does not have heat harvester, loses heat yet.

The purpose of this utility model is to provide a kind of efficient non-pressure civil boiler, makes cigarette, fire in the burner hearth form several eddy current, and collecting energy improves the thermal efficiency more fully, gathers the heat of furnace bottom simultaneously.

The technical solution of the utility model is as follows:

This boiler is respectively housing, water jacket, burner hearth from outside to inside, the crown center of housing is a chimney, water outlet, venthole that the top is communicated with water jacket in addition, the top of housing has shoot door, the middle part of housing has adjustable air vent, the middle part of housing also has delivery port, and the bottom of housing has scale removal hand hole and water inlet; The following of burner hearth is fire grate, opens on the fire grate and adds bin gate, and shoot door is opened in the grey chamber below it; At least be connected with two U-shaped plates that stretch out to oblique below on the inwall of burner hearth, this plate is upper and lower staggered, is water in the U-shaped plate and is communicated with water jacket; The position is stretched out below tiltedly by a side inwall at nethermost U-shaped plate, extends with the opposite side inwall to link to each other, and all is communicated with the both sides water jacket in this U-shaped plate, has an outlet flue on this U-shaped plate at least; In two U-shaped plate enclosed spaces heat-exchange tube can be arranged, this pipe is angled with horizontal plane, over against the position of chimney the one diameter thick heat-exchange tube bigger than chimney is arranged in upper furnace; Under grey chamber, the water heating casing is arranged.

Advantage of the present utility model is: 1, because added U-shaped plate makes cigarette, fire can produce eddy current in burner hearth, and the thick heat-exchange tube under the chimney also makes cigarette not go straight up to, increase the furnace bottom water jacket, all make heat can fully be gathered thermal efficiency height.2, scale removal, slagging-off are conveniently.3, sufficient combustion, discharge of noxious gases is few, alleviates environmental pollution.4, take up room for a short time, be fit to civilian.

Fig. 2 is the perspective view of U-shaped plate under the utility model;

Fig. 3 is that the utility model A--A is to schematic diagram;

Fig. 4 is the perspective view of the low water jacket of the utility model stove.

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

Can one see the integral body of this boiler and the structure of U-shaped plate by Fig. 1, Fig. 2, Fig. 3, it is respectively housing (3), water jacket (18), burner hearth (17) from outside to inside, the crown center of housing is chimney (10), the water outlet that the top is communicated with water jacket in addition, venthole (1), the top of housing has shoot door (2), the middle part of housing has adjustable air vent (4), and the middle part of housing also has delivery port (16), and the bottom of housing has scale removal hand hole (8) and water inlet (7); The following of burner hearth (17) is fire grate (20), opens on the fire grate and adds bin gate (19), and shoot door (23) is opened in the grey chamber (22) below it; (24) be base; Be connected with three U-shaped plate (12), (13), (15) of stretching out on the inwall of burner hearth to oblique below, be water in the U-shaped plate and be communicated with water jacket (18), the U-shaped plate is upper and lower staggered, the position is stretched out to oblique below by a side inwall at nethermost U-shaped plate (15), extend with the opposite side inwall and link to each other, all be communicated with both sides water jacket (18) in the U-shaped plate (15), open an outlet flue (6) in the junction of low side, there is stiffener (14) both sides of this U-shaped plate.Cloth heat-exchange tube (5) in two U-shaped plate enclosed spaces, this pipe become 30 ° of degree angles with horizontal plane, over against the position of chimney the one diameter thick heat-exchange tube (11) bigger than chimney arranged in upper furnace.

Can see the structure of the furnace bottom water jacket (21) of this boiler by Fig. 1, Fig. 4, it is under grey chamber (22), and this water jacket can be gathered the heat under the fire grate (20), and gusset plate (9) is arranged on the water jacket front and back walls.The upper wall of this water jacket tilts, and is convenient to ash disposal.
