Abstract

The utility model relates to an improved normal pressure hot water boiler for heating use, in particular to a power-saving heating boiler, comprising: a chimney mounted on a boiler body with a water inlet and a water outlet, and a heating chamber in the boiler body, wherein, the enclosed heating chamber with a pan bottom shape top surface is arranged above the boiler grate bars, the zigzag chimney is connected to the rear part of the heating chamber, the enclosed heating chamber and the zigzag chimney are arranged in the boiler body that is filled with water, and water channels passing through the inter-layer of the heating chamber are distributed evenly on the pan-bottom wall of the heating chamber. The utility model not only has a large heat inter-change area and a high thermal efficiency ratio, but also takes full advantage of the residual heat in the high-temperature flue gas to heat the water in the boiler; therefore, the heat exchange time is longer, and the black fume can be reduced; as the result, the utility model is power saving and helpful for environmental protection.

Description

The energy-saving heating boiler

Technical field

The utility model belongs to the improvement, particularly energy-saving heating boiler of the normal-pressure hot-water boiler of using for heating.

Background technology

Its structure of the most generally using of hot-water boiler of using for heating is water-tube boiler, uniform the heating pipe who is communicated with water jacket in the heating clamber of boiler.Flame in the stove supplies the heating of the water among the uniform heating pipe back heating or lives daily.Its heating properties is stable, and is safe and reliable.But its heating surface (area) (HS is big not enough, and heat exchange efficiency is limited, and the high-temperature flue gas behind the heating pipe is directly discharged by chimney, and the waste heat loss in the flue gas is many.

Summary of the invention

The purpose of this utility model is to provide a kind of energy-saving heating boiler, and not only its heat exchange area is big, and thermal efficiency ratio is higher; and making full use of water in the further heating boiler of waste heat in the high-temperature flue gas, heat exchanger time is long, reduces black smoke; energy savings helps environmental protection.

The purpose of this utility model is achieved in that a kind of energy-saving heating boiler, be included in the chimney and the interior heating clamber of body of heater that are being provided with on the body of heater that has water inlet and delivery port, the closed heating that end face is a bottom of a pan shape is being set above fire bars, the chimney that is connecting round complications at the rear portion of heating clamber, closed heating and tortuous chimney are arranged in the water-filled body of heater the uniform waterway that connects the heating clamber interlayer that is being provided with on the face of the bottom of a pan of heating clamber.

Because the utility model closed heating and tortuous chimney are arranged in the water-filled body of heater, increased significantly with body of heater in the heat exchange area of water, improved the thermal efficiency, saved the energy.The end face of fuel combustion on fire bars heating heating clamber the bottom of a pan shape, it is more even that the end face of heating clamber the bottom of a pan shape is heated, and makes the water quick heating in the boiler.The utility model comes and goes tortuous chimney has increased the running time of high-temperature flue gas in body of heater, and the high-temperature flue gas in the chimney fully carries out heat exchange with the interior water of body of heater, and the waste heat of flue gas is fully utilized.Round tortuous chimney makes the sootfall in the flue gas, has reduced black smoke, helps environmental protection.

Description of drawings

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

Fig. 2 is the sectional structure schematic diagram of the utility model embodiment 2;

Fig. 3 is the sectional structure schematic diagram of the utility model embodiment 3.

The specific embodiment

A kind of energy-saving heating boiler, embodiment 1 as shown in Figure 1, water inlet 1 and delivery port 5 are being set on body of heater 2, it is the closed heating 3 of the bottom of a pan shape that end face is being set above fire bars 6, closed heating 3 its structures are connecting the circular diffuser casing that volume increases for columniform combustion chamber above fire bars 6 by the clearance channel of shrinking, and the cross section of diffuser casing is trapezoidal.Connecting the chimney 4 of round complications on the diffuser casing at heating clamber 3 rear portions, stretch out from the top of body of heater 2 on the top of chimney 4.Closed heating 3 and tortuous chimney 4 are arranged in the water-filled body of heater 2 the uniform waterway 7 that connects heating clamber 3 interlayers that is being provided with on the face of the bottom of a pan of heating clamber 3.Fuel on the fire bars 6 is in columniform combustion chamber internal combustion, and burned flame enters the diffuser casing diffusion by the clearance channel of shrinking fully burns flame.The clearance height that is positioned at the clearance channel of floss hole one side in the heating clamber 3 is 2-4cm, and its clearance height that is positioned at the clearance channel of stove gate one side is 8-15cm.Make the flame distribution of heating clamber 3 even, prevent that flame from moving short circuit and directly taking away from flue.At the bending part of tortuous chimney 4 the deashing pipe 9 that is communicated with is being set, the outlet of deashing pipe 9 is arranged on corresponding body of heater 2 walls, is being provided with on body of heater 2 walls in the exit of deashing pipe 9 and is sealing up a door 8.During deashing, opening seals up a door 8 can remove dust stratification in the tortuous chimney 4 with instrument.

Embodiment 2 as shown in Figure 2 is divided into two chimneys of symmetry at the chimney 4 of heating clamber 3 back-connected round complications, the chimney 4 downward bendings respectively of symmetry, and the inwardly bending of turning back then upwards again collects in the chimney at body of heater 2 tops.High-temperature flue gas after heating clamber 3 fuel combustions moves downwards along chimney 4, turns back then upwards, and inwardly bending operation again, last flue gas collects in the chimney at body of heater 2 tops and discharges.The downward bending of chimney in the body of heater 2, turning back again upwards operation has prolonged the time of staying of high-temperature flue gas body of heater 2 in, and the waste heat of flue gas carries out heat exchange with the interior water of body of heater 2 fully, the water that heating furnace body 2 is interior.

Embodiment 3 as shown in Figure 3 is being provided with the heating clamber 3 of double seal in body of heater 2, connecting the corresponding tortuous chimney 4 that comes and goes respectively at the rear portion of each heating clamber 3, and its end collects in the chimney at body of heater 2 tops.
