Description

A kind of vertical boiler

Technical field: the utility model relates to a kind of heating plant, specifically a kind of vertical boiler.

Background technology: at present, civil boiler thermal output 58-62%, 380 ℃ of exhaust gas temperatures; Adopt the coal-burning boiler thermal efficiency 75-83% of medium tube economizer, exhaust gas temperature 260-280 ℃; The modern large-sized boiler thermal efficiency also has only 89-91%, and exhaust gas temperature is also more than 200 ℃.

Summary of the invention: the purpose of this utility model is, develops a kind of heat space of depositing that has, and exhaust gas temperature is controlled at about 100 ℃, improves the thermal efficiency, energy-conservation vertical boiler thereby reach.Its technology contents is, a kind of vertical boiler, by body of heater, water jacket, dividing plate, U type smoke pipe, partition wall, burner hearth, grate, exhaust opening, plate, chimney, water inlet pipe, outlet pipe, return pipe constitutes, it is characterized in that, in the body of heater, water jacket is provided with one deck dividing plate outward, dividing plate is provided with some U type smoke pipes, side under the dividing plate is provided with the burner hearth of a band partition wall, burner hearth has grate, the opposite side of partition wall is provided with little outlet flue and big outlet flue of a band plate, chimney will be big, little outlet flue is associated in together, and body of heater is provided with a water inlet pipe and an outlet pipe, and body of heater has a return pipe.Its operation principle, under the cold stoking situation, burn in the burner hearth heat that produced and hot cigarette enter the U type smoke pipe in the body of heater respectively under the effect of dividing plate and partition wall, and the little exhaust opening under body of heater is discharged from chimney then, as combustion-supporting with air blast, available plate is plugged little mouth.Burn in the burner hearth heat that produced and hot cigarette enters U type smoke pipe in the body of heater respectively under the effect of dividing plate and partition wall, the big exhaust opening under body of heater is discharged from chimney then.The utility model is compared its advanced part and is with prior art, this vertical boiler, have scientific structure,, do not reach the weak point of utilizing to greatest extent thereby overcome existing boiler thermal output by depositing the characteristics that heat space is fully used heat that the burner hearth internal combustion produced and hot cigarette.

Description of drawings:

This figure is just cuing open structural representation for the utility model;

Wherein, chimney 1, little outlet flue 2, big outlet flue 3, plate 4, body of heater 5, dividing plate 6, water inlet pipe 7, water jacket 8, outlet pipe 9, U type smoke pipe 10, partition wall 11, burner hearth 12, grate 13, return pipe 14.

The specific embodiment: this practicality is newly remake description further below in conjunction with accompanying drawing, in the body of heater 5, the water jacket 8 outer one deck dividing plates 6 that are provided with, dividing plate 6 is provided with some U type smoke pipes 10, dividing plate 6 next side are provided with the burner hearth 12 of a band partition wall 11, burner hearth 12 has grate 13, the opposite side of partition wall 11 is provided with little outlet flue 2 and big outlet flue 3 of a band plate 4, chimney 1 is associated in large and small outlet flue 3,2 together, body of heater 5 is provided with a water inlet pipe 7 and an outlet pipe 9, body of heater 5 has a return pipe 14, more than just constitute the utility model.
