Abstract

Disclosed is a high-efficiency energy-saving no-pressure furnace belonging to small-sized domestic heating boilers. The furnace is provided with a round internal furnace on the inner wall of the wholly-water-jacketed furnace body. A circular internal furnace with heating core-through pipe and a circular heating inside liner are arranged in the wholly-water-jacketed furnace body through horizontal connecting pipes and vertical connecting pipes from below and the waterways are interlinked. The central exhaust pipe is arranged between the round internal furnace and round heating inside liner which is connected with the wholly-water-jacketed furnace body by an inclined exhaust pipe. The furnace is a no-pressure water furnace which supplies heating through the natural flow of the temperature-increased water. The furnace is characterized by a simple structure, low cost, high heating efficiency, a large heating area and energy-saving and is safe and convenient for application.

Description

Energy-efficient non-press stove

Technical field

The utility model belongs to the heating boiler series products, mainly is applicable to the heating of local-style dwelling houses or back yard industry factory building.

Background technology

In the small towns or rural area of the northern area of China, residential building heating in winter is many promptly installs heat exchange structures such as water jacket additional with so-called " soil boiler " in stove and accessory, improving resident's living conditions, improves the environmental sanitation aspect and has played positive role.In recent years, continuous increase along with northern small towns and urban residents' area of residence, and the development of the middle-size and small-size township enterprise in rural area, original " soil boiler ", because reasons such as its structure are very unreasonable, and rate of heat exchange is low, not only energy waste is big, and heating area is little, can not satisfy and adapt to user's demand.

Summary of the invention

The purpose of this utility model is exactly technical problem and the deficiency that exists at widely used " soil boiler " in existing rural area or the residents from villages and towns dwelling house, a kind of energy-efficient non-press stove is provided, by enlarging stove Nei Shui and hot heat exchange area and prolongation heat exchange path and the structural design of time, reach the purpose that improves rate of heat exchange, enlarges heat supply heating area, energy savings.

Basic design of the present utility model is, energy-efficient non-press stove comprises burner hearth, coal filling hole, smokejack, clean-out door, return pipe and outlet pipe, on the full water jacket furnace internal chamber wall, burner hearth above utilize horizontal connection tube installing to have the round flue of heating punching pipe, and the water jacket of full water jacket furnace communicates with round flue; The inwall of full water jacket furnace, be positioned at round flue above be provided with ring-like flue, utilize vertical tube connector that round heating courage is packed on the ring-like flue, the water route communicates; Equipped central row tracheae between round flue and round heating courage, the exhaust inclined tube is connected round heating courage and full water jacket furnace; On the sidewall of full water jacket furnace, be positioned at ring-like flue top and be provided with the dedusting mouth, so far constitute energy-efficient non-press stove.

The utility model is no setting-out stove, by the water temperature heat supply of flowing voluntarily that raises, have simple in structure, with low cost, the thermal efficiency is high, heating area is big, energy savings, characteristics safe and convenient to use.
