Description

A kind of boiler

Technical field

The utility model relates to a kind of power economized boiler.

Background technology

The structure of plain cylindrical furnace generally is that water tank is set on every side in the combustion chamber, and directly to the water tank heating, perhaps flame and the hot flue gas that utilizes burning to produce heats water tank the combustion chamber fuel combustion.For miniature boiler, because the space is little, flue gas contacts abundant inadequately with water tank, so the thermal efficiency is not high, and a large amount of heat energy are discharged with the flue gas that burning produces, and cause energy waste.In addition, in places such as family, dining rooms, common boiler can only be used for heating up water, function singleness, and cooking then needs to use with an other cover heating stove and accessory.So also be a kind of waste, increased cost device resource.

The utility model content

Technical problem to be solved in the utility model provides a kind of fuel savings, the boiler that the heat energy utilization rate is high; Also provide a kind of in addition and not only can be used as the boiler of heating up water, but also can be used as the externally boiler for dual purpose of heating of common heating furnace.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of boiler, comprise combustion chamber and water tank, and described water tank is made up of inner bag and shell, and the space between inner bag and the shell is the storage area, and the inner bag inner space is an exhaust gases passes; The engine firewall that described inner bag is provided with a plurality of hollows and is communicated with the storage area, described engine firewall is mutually staggered from stretching out to the middle part on every side; Tank top is provided with outlet flue.

On the basis of technique scheme, the utility model can also be done following improvement.

For increasing the contact area and the time of contact of flame and flue gas and inner water tank, improve heat exchanger effectiveness, the section of described engine firewall is a falcate, and its end is bent downwardly.The lower surface of described engine firewall is provided with the heat absorbing sheet of circular array, improves endothermic effect.

Similar with plain cylindrical furnace, water tank inside is located in the combustion chamber.Lower space in the described inner bag is the combustion chamber.Flame and flue gas that burning produces directly pass from the water tank exhaust gases passes, and the water in the water tank is heated.Because unique falcate engine firewall has increased the contact area and the time of contact of flame, boiler combustion heat utilization efficiency height, heating is fast, fuel saving.

For realizing simultaneously can be to the purpose of external heat, the combustion chamber also can be independent of water tank.Boiler also comprises body of heater like this, and described body of heater is made up of combustion chamber and housing, and top, described combustion chamber is provided with opening, forms cavity between combustion chamber and the housing, and described cavity communicates with combustion chamber openings; Described water tank is located at a side of body of heater, and the middle and upper part of water tank and bottom are respectively equipped with the air inlet that the water tank exhaust gases passes is communicated with the body of heater cavity, and wherein the air inlet place of water tank middle and upper part is provided with the air inlet gate, controls the unlatching of this air inlet or closes.Further, be provided with water tank around the described body of heater inner combustion chamber, to make full use of calory burning.

Need cook or during to external heat, open the gate between body of heater cavity and the water tank exhaust gases passes, flue gas enters exhaust gases passes from gate, because position of strobe is near the middle and upper part of water tank, flue gas resistance is less can smooth and easyly discharge, the combustion chamber high firepower of fuel combustion intensity is good, can provide sufficient heat for external heat.In the time of need heating the water in the water tank, closed shutter, hot flue gas enters from the air inlet of water tank bottom, and flue gas is longer at the water tank internal process, and heat is fully absorbed by water tank, the heat utilization efficiency height of water tank.Engine firewall in the water tank forms around the rotation thermal current flue gas.The number row herringbone heat absorbing sheet of curved month type engine firewall bottom absorbs heat, and elongating flame simultaneously increases contact area.The top the rotation thermal current can fully scorch following inner bag half-moon-shaped above, heat is fully utilized.Therefore the utility model both can be used for the water heating, can be used as again that the heating stove and accessory is used to cook or other need be to the occasion of external heat.This boiler is particularly useful for the household small-size heating system, can be used as the special-purpose stove of floor heating.
