Description

Novel double-combined boiler

Technical Field

The utility model belongs to the technical field of the boiler is made, especially relate to a novel biomass boiler.

Background

In engineering, there are many cases where the heat load is high and a large steam flow is required. If one steam boiler is used for supplying steam, the operation is not economical under low-temperature coincidence, not only the combustion efficiency is low and energy is consumed, but also the operation is unstable and the flameout is often caused, so that the production is influenced by the shutdown of the boiler, and when the double-combined boiler is applied, the normal operation can be realized under the very low heat load. When 50% load is needed, one furnace can be used for working, when 25% heat load is needed, one furnace can be used for working under 50% load, the boiler can stably operate under the load, and when 100% load is needed, the double-combined boiler can simultaneously work. The double combined boiler can work normally in the range of load change, which is not enough for the common boiler.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel two recombinations boilers can reduce the heat dissipation loss of boiler, provides boiler thermal efficiency, reduces the operation maintenance passageway between stove and the stove, has saved area.

The utility model discloses a realize through following technical scheme: a novel double-combined boiler comprises a single boiler, wherein the single boiler comprises a boiler body, a boiler wall, a coal hopper, a grate, a hearth and a boiler barrel, the boiler wall is fixedly connected to the inside of the boiler body, the coal hopper is arranged on the outside of the boiler body, the grate is arranged on the lower side of the inside of the boiler body and is connected with the coal hopper, the hearth is arranged inside the boiler body, the boiler barrel is arranged at the upper end of the boiler body, an air outlet, a left side wall, a right side wall, a front wall upper header, a hearth front wall, a hearth rear wall, a front wall lower header, a rear wall upper header, a down pipe, a channel rear wall lower header, a rear wall lower header and a serpentine pipe which are communicated with the inside of the boiler body are sequentially arranged inside the boiler barrel, the left side wall upper header, the right side wall lower header, the left side wall lower header and right side wall lower headers are arranged on the left, the lower extreme is equipped with the ash bucket, air heater passes through under economizer and the passageway rear wall collection box and the collection box communicates its characterized in that under the rear wall: the boiler bodies of the two single boilers are integrated, the middle of each single boiler body is separated by a shared boiler wall, the top parts of the boiler barrels at the tops of the two single boilers are provided with steam outlets, and the two steam outlets are communicated through a connecting pipe and are opened to one side.

Furthermore, the two drums are respectively provided with an adjusting valve.

Has the advantages that: the utility model discloses simple structure, convenient to use can reduce the heat dissipation loss of boiler by two boiler combination one boiler, provides the boiler thermal efficiency, reduces boiler operation personnel's number, uses manpower sparingly and expense, reduces the operation maintenance passageway between stove and the stove, has saved area.
