Abstract

The utility model relates to a movable efficient coal saving stove for families, which adopts a specially designed residual heat chamber and determines the proportion of the relevant part of the stove. The utility model achieves high residual heat utilizing rate and improves the effect of the main fire.

Description

A kind of adjustable household high-efficient coal-saving kitchen range

The utility model belongs to a kind of domestic life coal kitchen range.

At present the used advanced coal-saving range of people is formed (see the Hunan Province State Scientific and Technological Commission, Hunan Province's energy research can compile in collaboration with " civilian firewood and coal saving kitchen range atlas ") by hot-tub, flue, air channel, secondary air duct, smoke pipe etc.But the waste heat of flue dust is not utilized in the smoke pipe, and the annular heat water pipe and the flue in pond are nearer, and the heat of absorption is the flue heat radiation, has influenced main fire like this, and the thermal efficiency of kitchen range is low.

The purpose of this utility model is to provide a kind of can make full use of flue dust waste heat and don't the main fire of influence, the coal-saving range that the thermal efficiency is higher.

The utility model is provided with an annular waste heat chamber (8) in stove (1), ring-shaped water jacket (7) is indoor at waste heat, and flue entrance (6), smoke pipe (12) communicate with the waste heat chamber, and the space between waste heat chamber and the ring-shaped water jacket constitutes the smoke evacuation interlayer.The ring-shaped water jacket inwall is near flue (2), heat-insulation layer (15), outer wall is the smoke evacuation interlayer, and ring-shaped water jacket not only can reclaim the furnace wall heat radiation like this, and can reclaim the flue dust heat, link to each other with pond (10) with upper and lower conduit (9), utilize water circulation theory preheating heat pond.Water jacket inwall and flue have certain distance, and heat insulation with insulation material, do not influence main fiery temperature like this, reach the purpose of UTILIZATION OF VESIDUAL HEAT IN.

The ratio of wind passage mouth (3) area of section of the utility model and flue area of section suitable for reading, smoke pipe area of section is 1:3:1, the ratio of wind passage mouth area of section and secondary air duct mouth (4) area of section is 6～9%, to improve the thermal efficiency, in order to accelerate flue gas velocity, smoke pipe elbow (11) area of section is 110～200% with the ratio of smoke pipe area of section, and the smoke evacuation interlayer area of section is 1.2:1 to 2:1 with the ratio of smoke pipe area of section.

The utility model is compared with existing coal-saving range, and waste heat efficient reaches 15.25%, and leads fiery efficient up to 56.08%, and overall thermal efficiency reaches 71.33%; Use clean, sanitary, pollution-free.

Embodiment:

Press shown in the accompanying drawing, this kitchen range is made of body of heater (1), flue (2), a wind passage mouth (3), secondary air duct mouth (4), surrounded burning ring (5), flue entrance (6), ring-shaped water jacket (7), annular waste heat chamber (8), upper and lower conduit (9), pond (10), smoke pipe elbow (11), smoke pipe (12), grey chamber (13), heat-insulation layer (14,15), the indoor footpath of wherein annular waste heat is that 320mm, external diameter are 350mm, and height is 160mm.Ring-shaped water jacket is indoor at waste heat, and the interlayer width of ring-shaped water jacket and waste heat chamber is 15mm, and a wind passage mouth diameter is 62mm, secondary air duct mouth diameter is 18mm, and the smoke pipe elbow diameter is 76mm, and the smoke pipe diameter is 62mm, the flue entrance diameter is 260mm, and high 8mm, the thermal efficiency are 70%.

Claims

1, a kind of flue that comprises, water jacket, the pond, an air channel, secondary air duct, the high-efficient coal-saving kitchen range of smoke pipe, it is characterized in that being provided with in the stove (1) one and flue entrance (6), the waste heat chamber (8) that smoke pipe (12) communicates, the space of ring-shaped water jacket (7) and waste heat chamber constitutes the smoke evacuation interlayer, the ratio of wind passage mouth (3) area of section and secondary air duct mouth (4) area of section is 6～9%, smoke pipe elbow (11) is 110～200% with the ratio of smoke pipe area of section, the flue entrance area of section is 1.5: 1 to 2: 1 with the ratio of smoke pipe area of section, and the smoke evacuation grieshoch area of section is 1.2: 1 to 2: 1 with the ratio of smoke pipe area of section.
