Abstract

The utility model relates to a vertical and normal-pressure hot water boiler using fuel and gas. A boiler body is connected with a water inlet pipe and a water outlet pipe. One side of a boiler hearth is provided with a flame inlet. The upper part of the interior of the boiler body is provided with a fume box. The upper part of the fume box is communicated with a fume exhaust opening. The boiler hearth and the fume box are communicated with a plurality of biased cylindrical fume pipes. A circular tube type fume guide plate is arranged between the lower parts of the fume pipes and the upper part of the boiler hearth. The periphery wall of the boiler body and the lower half part of the interior of the boiler hearth are lined with a flameproof heat-insulating layer. The upper half part of the boiler hearth, the fume pipes and the fume box are provided with wavy heat exchange fins. The utility model adopts the structure designs of the heat exchange of the fins and the fume guide of the fume guide plate, enlarges the heat exchange area, reduces the resistance force of the fume, improves the heat efficiency, and reduces the energy consumption.

Description

Vertical fuel-firing gas-firing normal-pressure hot-water boiler

The utility model relates to a kind of vertical fuel-firing gas-firing normal-pressure hot-water boiler.

At present, normally used vertical oil burning boiler exists generally that heat-conducting area is few, the thermal efficiency is low, burning was insufficient when cold conditions was on fire, flue gas resistance big, the easy shortcoming such as long-pending crock of boiler tube burner hearth, thereby big energy-consuming, need often maintenance, influenced life cycle and polluted environment.

The purpose of this utility model is to provide a kind of improved vertical fuel-firing gas-firing normal-pressure hot-water boiler, overcome the weak point that original vertical oil burning boiler exists, make it have quick heating, pollution-free, usefulness such as noise is little, automaticity height, improve boiler thermal output greatly, reduced energy consumption.

The purpose of this utility model is achieved in that and is provided with red of heat exchange in the burner hearth first half, smoke pipe and the smoke box of vertical oil burning boiler, increase heat exchange area, and in body of heater perisporium and burner hearth Lower Half, be lined with refractory insulating layer and upper furnace is provided with smoke deflector.When the flame of burner ejection enter stove often in, because furnace wall and lower furnace portion are lined with the refractory insulating layer structure, make flameholding abundant, improved temperature in the burner hearth, high-temperature flue gas enters smoke pipe along efficient red balanced of process of smoke deflector all around, this heat exchange flow-guiding structure has not only increased heat exchange area, and has reduced the resistance of flue gas.Enter smoke box after red heat exchange again, after the red heat exchange in smoke box, useless flue gas is discharged outside the body of heater again.Its heat is fully utilized high-temperature flue gas, thereby has improved the thermal efficiency of boiler greatly repeatedly repeatedly after the heat exchange through red, has reduced energy consumption and to the pollution of environment.

The utility model is improved on the existing equipment structure, adopts the structural design of red heat exchange and smoke deflector water conservancy diversion, has strengthened heat exchange area and has reduced flue gas resistance, thereby reduced energy consumption and pollution, has improved the thermal efficiency of boiler.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the B-B cutaway view of Fig. 1.

Fig. 4 is a smoke pipe drawing in side sectional elevation of the present utility model.

Shown in Fig. 1-4, a kind of vertical fuel-firing gas-firing normal-pressure hot-water boiler, it includes a body of heater (1), be connected to water inlet pipe (4) and outlet pipe (5) on the body of heater (1), body of heater (1) bottom burner hearth (2) one sides have the flame import (3) of burner, body of heater (1) internal upper part is equipped with smoke box (7), be communicated with exhaust opening (8) above the smoke box (7), it is characterized in that: have many inclined to one side column type smoke pipes (6) to be communicated with between burner hearth (2) and the smoke box (7), be provided with tubular type smoke deflector (9) between smoke pipe (6) bottom and burner hearth (2) first half, body of heater (1) perisporium and the interior Lower Half of burner hearth (2) are lined with refractory insulating layer (10), at burner hearth (2) first half, be provided with red of the heat exchange that is ripple type (11) in smoke pipe (6) and the smoke box (7).During use, the flame of fuel oil or combustion gas ejection enters burner hearth (2), because of wall in the stove has refractory insulating layer (10), prevent heat diffusion, make burning more stable more abundant, the interior temperature of burner hearth (2) is improved, high-temperature flue gas passes through efficient red (11) heat exchange because of the effect of thorax stove top smoke deflector (9) all around equably along smoke deflector (9) and enters smoke pipe (6), above entering after red (11) heat exchange in smoke pipe (6) again in the smoke box (7), red (11) heat exchange in smoke box (7) again, useless then flue gas discharges out of the furnace through exhaust opening (8).Through red heat exchange several times, heat is fully utilized, thereby the thermal efficiency of boiler is improved greatly.
