Abstract

An energy-saving kettle with a high-efficiency fire tube is used for boiling water in industry or civil use. In particular, the high-efficiency fire tube energy-saving kettle is composed of a kettle body, a kettle lid and a kettle fire tube bundle. The kettle fire tube bundle is immersed in the kettle water. The tube bundle heats the pot of water quickly, which greatly saves fuel and time.

Description

Efficient fire tube energy-saving water jug

Affiliated technical field

The utility model relates to a kind of efficient fire tube energy-saving water jug, is applied in industry or civilian boiling water.Especially efficient fire tube energy-saving water jug is by kettle kettle body, kettle pot lid and kettle fire tube Shu Zucheng, kettle fire tube bundle is immersed in the kettle water, when kettle is placed on when heating up water on the cooking stove, flame on the cooking stove and high-temperature flue gas to kettle water Fast Heating, have been saved fuel and time through kettle fire tube bundle greatly.

Background technology

Kettle is the cooker of heating up water that China family generally adopts, and is the plane at the bottom of traditional kettle kettle, and heating surface area is little at the bottom of the kettle, burned flame and the high-temperature flue gas that flows heat time heating time at the bottom of to kettle is very short just drains, Btu utilization is insufficient, and the efficiency of heating surface is low, has wasted fuel and time greatly.After, people have connected two water pipes again below the bottom of kettle, be used for enlarging the heating surface area at the bottom of the kettle and increase disturbance to the kettle inner cold water, can improve the thermal efficiency of kettle among a small circle.But, face increases by two water pipes to increasing kettle heating surface area and little under kettle, on the contrary, because water pipe is very thin again below the bottom of kettle, be very easy to internal junction incrustation scale at water pipe, incrustation scale in the water pipe can easily not clean again, causes the kettle bottom tube to cross cause thermal damage and can not use again, does not have well to solve the energy-efficient increase of the kettle problem in service life.

Summary of the invention

In order to solve the problems referred to above that kettle is heated up water and existed, the utility model provides a kind of efficient fire tube energy-saving water jug.This efficient fire tube energy-saving water jug is little at ordinary canteen bottom heating surface area, inner cold water circulation is slow, and the easy fouling of water receiving pipe is stopped up and problems such as mistake cause thermal damage below the kettle bottom, designed efficient fire tube energy-saving water jug, flame that produces when making the cooking stove burning and high-temperature flue gas are by the fire tube of kettle inside, carry out heat exchange with the kettle inner cold water, because kettle internal fire pipe quantity is many, fire tube is long, has improved the heating surface area of kettle greatly, has also improved the convection circulation intensity of kettle inner cold water effectively, increased convective heat-transfer coefficient, effectively improve the thermal efficiency of kettle, simultaneously, also avoided the flimsy problem of water pipe internal junction incrustation scale.

The technical scheme that its technical problem that solves the utility model adopts is: the thin iron pipe of arranging some in the kettle internal vertical, the lower end of thin iron pipe and kettle bottom connect, the upper end of thin iron pipe and the kettle oral-lateral face of kettle connect, a plurality of thin iron pipe bundles have been formed in the inside of kettle, flame and high-temperature flue gas all pass through these iron pipe bundles, so claim the fire tube bundle.Because these fire tube bundles place cold water, heating surface (area) (HS is big, and convection heat transfer' heat-transfer by convection is good, and the intrafascicular heat of fire tube is used effectively, and has improved the thermal efficiency of kettle greatly, has shortened heat time heating time.Also since the fire tube bundle for being arranged vertically, the flow of flue gas resistance is little, it is unobstructed discharge fume, and the effect of attraction flame is arranged, the high-temperature flue gas overwhelming majority that cooking stove burns has been passed through this fire tube bundle, the flue-gas temperature of discharge is very low, the heat effective rate of utilization is very high.

The beneficial effects of the utility model are: China is populous, and the consumption of domestic hot water is very big, the method for in the past heating up water, because the thermal efficiency is low, waste of fuel is big, and heat time heating time is long, all can not be ignored to the consumption of the energy with to the influence of environment.Efficient fire tube energy-saving water jug has effectively increased the heating surface area of kettle; improved convection heat transfer' heat-transfer by convection effect in the kettle; made full use of the high-temperature flue gas heat that fuel combustion produces, the complex heat transfer coefficient height, exhaust gas temperature is low; heat time heating time is short; thermal efficiency height has been saved fuel, has protected environment; improved quality of life, bigger economic benefit and social benefit have been arranged.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model principle schematic.

Among Fig. 1,1, kettle kettle body, 2, the kettle pot lid, 3, kettle fire tube bundle.

Specific embodiments

Efficient fire tube energy-saving water jug is made up of kettle kettle body 1, kettle pot lid 2 and kettle fire tube bundle 3.Kettle fire tube bundle 3 is arranged vertically in kettle, connect at the bottom of the bottom of kettle fire tube bundle 3 and the kettle, the side of its top and kettle kettle body Hu Kou connects, flame and high-temperature flue gas that the cooking stove burning produces, because the vertical smoke evacuation sucking action of kettle fire tube bundle, the overwhelming majority is all passed through kettle fire tube bundle, outside discharge kettle after the abundant heat exchange of kettle inner cold water, in kettle water heating process, kettle water heating surface area is big, the convective heat-transfer coefficient height, the disturbance of kettle inner cold water is strong, and is low through the flue-gas temperature behind the kettle fire tube bundle, complex heat transfer efficient height, the fuel availability height, heat time heating time is short.

Claims (2)

1, a kind of efficient fire tube energy-saving water jug, by kettle kettle body, kettle pot lid, kettle fire tube Shu Zucheng, it is characterized in that: kettle fire tube bundle is made up of one group of thin iron pipe.

2, efficient fire tube energy-saving water jug according to claim 1 is characterized in that: connect at the bottom of the lower end of kettle fire tube bundle and the kettle kettle, its upper end connects with kettle kettle oral-lateral face.
