Abstract

The utility model relates to a high-efficiency domestic energy-saving boiler, which comprises a vertical combustion chamber and a flue communicated with the combustion chamber; the combustion chamber and the flue are water jackets with sandwich structures; the water jackets are communicated; a water circulation inlet and outlet can be arranged on each water jacket; the inlet and the outlet are communicated through a water pipe; at least one position of the inner walls of the combustion chamber and the flue can be corrugated along the radial direction distribution. The heating area of the water jackets can be increased by the corrugated shape of the utility model; the contact surface of the corrugated structure in the combustion chamber and burning coal can be reduced; the ventilation property can be better increased. The utility model improves the burning value of the coal; the heating area can be enlarged; the energy can be saved; the manufacture cost can be reduced; the utility model can be widely used for civil boilers.

Description

The high efficiency civil power economized boiler

The utility model relates to a kind of boiler, particularly a kind of high efficiency civil gas fired-boiler.

General civil boiler adopts flat water jacket, because water jacket has water, fire coal is large tracts of land contact water jacket again, make coal-fired temperature reduction in the stove, coal turns black around generally showing as water jacket, and coal-fired temperature does not reach optimum efficiency, because ignition temperature is low, cause most of heat energy not have burned and run away, greatly reduce the coal-fired thermal efficiency, coal-fired temperature is low, and water temperature does not increase, also just can not have in enough heat supply chambers, in order to reach the temperature of design, will increase the diameter of stove, prolong heating time, so just produce a kind of bad endless form, caused a large amount of wastes.

It is big that the purpose of this utility model provides a kind of heating surface area, the high efficiency civil power economized boiler that combustion thermal efficiency is high.

The purpose of this utility model realizes by following structure: it comprises the flue that vertical combustion chamber is communicated with the combustion chamber, combustion chamber and flue are the water jacket of sandwich and are interconnected, fixing the recirculated water inlet on the water jacket, on the flue water jacket, fixing circulating water outlet, inlet passes through cross current with outlet, and it is along its radially-arranged row of tiles on a roof shape that the inwall of combustion chamber and flue has a place at least.

The row of tiles on a roof that the utility model combustion chamber radially distributes has reduced contact area coal-fired and water jacket, so just reduced the low influence to fire coal of jacket water temperature, and this kind structure has increased more than 50% the heating surface area of water jacket.The high temperature that fire coal is produced conducts the recirculated water in the water jacket to greatest extent in the unit interval, thereby reaches benign cycle.Oxygen is one of essential condition of burning, and plain cylindrical furnace ubiquity oxygen supply deficiency causes burning insufficient, row of tiles on a roof structure of the present utility model makes air recessed to feeding the combustion chamber along each row of tiles on a roof, improves ventilation more than three times, coal is fully burned, has improved efficiency of combustion.Row of tiles on a roof structure in flue has increased the endotherm area of flue.In order to improve the heating surface area of flue, also be provided with a plurality of cyclic water jackets in the flue, the heat in the flue gas more is used for transforming the raising water temperature.The utility model reaches more than 1400 ℃ the burning of coal temperature, and coal has obtained abundant burning, has brought into play the higher thermal efficiency.Water temperature raises soon in the utility model unit interval, and water temperature can remain on 90 ℃ with cocycle, and for the stove of same size, furnace temperature can improve 300 ℃-400 ℃, and the utility model can reach designing requirement, extensively promotion and application through experimental results show that.

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment:

The utility model as shown in Figure 1, comprise the flue 2 that is communicated with combustion chamber 1 in the vertical combustion chamber 1, combustion chamber 1 is the water jacket of sandwich with flue 2 and is interconnected, fixing recirculated water inlet 3 on the water jacket, on flue water jacket 2, fixing circulating water outlet 4, inlet 3 passes through cross current with outlet 4, and it is along its radially-arranged row of tiles on a roof 5 shapes that the inwall of combustion chamber 1 and flue 2 has a place at least.Combustion chamber 1 all has the row of tiles on a roof shape with flue 2 in the present embodiment, and this kind structure heating surface area is big, and the heat energy conversion ratio is higher.A plurality of hollow cylinders 6 that formed by sidewall that distributing vertically in the described flue, the upper and lower of cylinder 6 all have the passage 7 that is communicated with the water jacket sealing of flue.
