Description

Horizontal multi-radiation energy-saving multi-purpose normal pressure boiler

The utility model relates to a kind of hot-water boiler, is a kind of horizontal multiple-radiation energy-saving multipurpose atmospheric boiler.

At present, the boiler kind of selling on the market is a lot, normal-pressure hot-water boiler has tens kinds, has plenty of the '30s flue tube boiler, and water jacket boiler is also arranged, immediate with the present invention is horizontal many backhauls of water jacket water pipe normal-pressure hot-water boiler, the patent No. is 892007214, and this boiler is made up of three parts, the one, and the combustion chamber is an arched water jacket, the 2nd, there is collector pipe both sides and back, the 3rd, oval water tank is arranged at top, and coal burns under water jacket, and flue gas is by rear blocking plate back both sides collector pipe, by rising on the oval water tank bottom, enter chimney and discharge, this furnace thermal efficiency has raising, can reach 76%, but also have as follows: 1, the thermal efficiency is also low, both sides and back collector pipe are close to refractory brickwork, when collector pipe absorbs heat, are also absorbed by refractory brick, besides flue gas flow direction is also not too reasonable, does not make full use of heat energy; 2, dust removing effects is poor, and 3, can only heating not have its and use.

The purpose of this utility model is design a kind of " horizontal multiple-radiation energy-saving multipurpose atmospheric boiler ", and low to solve the thermal efficiency, purposes is single, dust removing effects difference problem.

The purpose of this utility model is achieved in that this stove is by the semicircle water jacket in combustion chamber, both sides and back collector pipe, and header tank and water screen tube four parts are formed.There is the burner hearth header both sides under the semicircle water jacket, after the connection closure plate is arranged, on the last arched top flue is arranged, the rectangular set water tank is arranged above the flue, be provided with communicating pipe between header tank and water jacket, both sides are provided with the lower collecting box pipe in water jacket, and front end has water inlet pipe, water screen tube is arranged above, making progress from flue, both sides are crooked to be communicated with the upper header pipe, on the upper header pipe outlet pipe is arranged, outside water jacket on the both sides burner hearth header, be arranged with economizer bank along burner hearth, the economizer bank other end communicates with the upright header in back, is provided with the fiery closure plate of retaining in the burner hearth upper back, and there is flue its underpart, its back is provided with the back upper header, back lower collecting box, between be connected with the back header economizer bank, there is the upright header in back both sides, back lower collecting box is provided with water inlet pipe, is connected to cyclone dust collectors in the flue collector back.

The utility model compared with prior art has the following advantages: 1, cold water enters and flue gas adverse current from behind, and pre-heat effect is good, and Btu utilization is abundant; 2, the combustion chamber is semicircle water jacket, flame can directly be heated up water the cover inboard after flue gas rises from flue, can directly burn header tank, after flue gas is obstructed, flue gas can directly burn both sides economizer bank and the water jacket outside to the both sides wraparound, after flue gas passes the fiery closure plate of retaining, can directly touch mutually, directly exchange heat energy with back upper header, back economizer bank, back lower collecting box again, the thermal efficiency be up to 82-85%; 3, be provided with the lower collecting box pipe in the water jacket inboard, water inlet pipe and water screen tube, upper header pipe and shower outlet pipe are arranged above, it directly contacts with flue gas, and the fast leaving water temperature that is heated can be cooked drinking-water and use more than 98 ℃; 4, grate area is big, and flame is rotary and advances, and the bulky grain dust easily descends; be thrown to burner hearth; when flue gas rose to the flue top, flame was stopped by a header tank and a retaining closure plate, to the both sides wraparound; when flue gas passes through the both sides economizer bank; dust descends once more, when flue gas passes the fiery closure plate of retaining after rear water collecting pipe dedusting once more, after the cyclone dust collectors dedusting; continuous four good dedusting effect, ash discharge concentration＜100mg/m ³, lingemann blackness＜1; 5, purposes is many, can supply drinking-water, warm water and heating simultaneously; 6, adopt gravity-flow ventilation, without air blast, air-introduced machine small investment, power saving; 7, volume is little, economizes steel, cost is low.
