Abstract
The utility model relates to a gas-fired waste-gas combined boiler and belongs to the technical field of boilers. The gas-fired waste-gas combined boiler comprises a boiler cylinder (1), wherein a boiler furnace (4) is arranged in the boiler cylinder (1); a fume tube (3) is arranged at the top of the boiler furnace (4); a needle tube component (2) is arranged in the fume tube (3) and comprises a circular tube (2.1); a plurality of steel needles (2.2) are welded on the peripheral wall of the circular tube (2.1); and two ends of the circular tube (2.1) pass through the fume tube (3) and are communicated with an external cavity of the fume tube (3). The gas-fired waste-gas combined boiler has the advantages that: the needle tube component is arranged in the fume tube, the heat exchange area of the boiler and high-temperature fume is increased, and the heat exchange efficiency of the boiler is effectively improved.
Description
Technical field
The utility model relates to a kind of fuel oil waste gas composite boiler, belongs to the boiler technology field.
Background technology
Fuel oil waste gas composite boiler is a kind of marine boiler, and the heat of the high-temperature flue gas that it produces when passing through diesel oil or fuel oil combustion and diesel engine work produces steam, thus the usefulness of supply arrangement anti-freezing and heat-insulating and life heating.Present fuel oil waste gas combined boiler is mainly through the water generates heat exchange in smoke pipe and the boiler, so its heat exchange area is less, and the heat exchange effect is relatively poor.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides that a kind of heat exchange area is big, the fuel oil waste gas composite boiler of good effect of heat exchange.
The purpose of the utility model is achieved in that a kind of fuel oil waste gas composite boiler; It comprises boiler barrel, is provided with flue in the said boiler barrel, and said flue top is provided with smoke pipe; Be provided with aciculiform pipe assembly in the said smoke pipe; Said aciculiform pipe assembly comprises pipe, and welding is provided with some draw points on the said pipe periphery wall, and said pipe two ends are passed smoke pipe and are connected with the smoke pipe external cavity.
Compared with prior art, the beneficial effect of the utility model is:
A kind of fuel oil waste gas of the utility model composite boiler, its smoke pipe set inside has aciculiform pipe assembly, has increased the heat exchange area with high-temperature flue gas, has effectively improved the heat exchange efficiency of boiler.
