Abstract
An oil and natural gas burning environmental protection boiler comprises a base, a steel frame, a boiler barrel and an oil and natural gas burner. A layer of refractory cement is poured onto the base, the steel frame is fixed on the base, the boiler barrel is fixedly connected to the upper end of the steel frame, a combustion chamber with four sides closed is constructed at the periphery of the steel frame by using refractory bricks, and the top surface of the combustion chamber is constructed to be an arc-shaped oblique and long stove arch for partitioning the bottom of the boiler barrel. The oil and natural gas burner is mounted at the tail end of the combustion chamber, and long-distance flame spraying to the combustion chamber can be achieved through a burning spray nozzle. Two layers of smoke pipe bundles are arranged inside the boiler barrel, so that all hot flue gas inside the combustion chamber is enabled to enter the boiler barrel to exchange heat with cold air entering from an air intake door, and hot air enters a hot air using spot from a hot-blast outlet. According to the utility model, through two return strokes of heat exchange of the heated pipe bundles inside the boiler barrel and exterior insulation treatment of the boiler barrel, the heat efficiency of the boiler is improved greatly, and the heat efficiency can reach 79 percent. The oil and natural gas burning environmental protection boiler has the advantages of energy conservation, environmental protection, high heat efficiency, safety, reliability, stability in operation and strong applicability.

The utility model content
The technical problems to be solved in the utility model is, provides a kind of and can boiler body and heat pipe binding be combined and can not burn the boiler tube bank of being heated.Make the flame distance of burner hearth, the just hyperthermia radiation temperature of tube bank of being heated, flame can not directly contact tube bank two backhauls of being heated with smoke pipe and return cigarette, and heating surface area increases, good effect of heat exchange, the thermal efficiency improves greatly.It is scientific and reasonable for structure, and technique is very simple, compact conformation, and attractive in appearance beautiful, applicability is strong, has stable, safe and reliable.Be convenient to processing and fabricating, save material cost, improve boiler thermal output, reduce heat loss, the thermal efficiency of boiler is up to more than 85%.Boiler body configuration Burner Technology advanced person, automatic ignition, microcomputerized control, and be furnished with natural gas leakage alarm control system, if any gas leakage, the circuit automatic disconnection, make the operation of boiler safer, more reliable.More can save for the user fuel oil combustion natural gas hot blast environment-protection boiler of boiler room construction investment.
The technical scheme adopted is:
Fuel oil combustion natural gas hot blast environment-protection boiler, comprise base, steelframe, drum, natural gas oil burner.Described base is angle frame pattern base, build one deck refractory cement on base, steelframe is fixed on base, drum is fixedly connected on the steelframe upper end, refractory brick and thermostable high-alumina cement masonry for the steelframe surrounding, and the wall body placing heat-insulating brick, build into end face, bottom surface, circumferential closed combustion chamber by laying bricks or stones outside, wherein end face is built into the arc plagioclase chimney arch that separates high-temperature heating with boiler drum bottom by laying bricks or stones.Combustion natural gas oil burner is installed, the jet flames by burner noz(zle) to burning interior length distance in the outside of combustion chamber tail end.Two-layer smoke pipe tube bank is set in described drum, establish the wind isolation board that a upper lower drum is separated between two-layer smoke pipe tube bank, form be heated smoke pipe tube bank of two backhauls, offer a hot flue gas inlet port that enters drum at tail end arc plagioclase chimney arch place, combustion chamber, the bottom that makes hot flue gases all in combustion chamber the enter drum smoke pipe that is heated is restrained the stokehold end warp-wise first half and is returned the cigarette smoke pipe and enter be heated smoke pipe tube bank of top, carry out heat exchange with the cold wind entered by shutter, hot blast by hot-blast outlet to using the hot blast place.Afterbody at drum is provided with a smoking box be communicated with chimney, and low-temperature flue gas is discharged by chimney smoothly.
Above-mentioned drum exposed parts is installed with heat-insulation layer.
Above-mentioned the place ahead, combustion chamber is provided with inspection door.
The front and back end of above-mentioned drum is respectively equipped with before drum shoot door after shoot door and drum.
The utility model is incubated processing outward by be heated tube bank heat exchange and drum of two backhauls in drum, has improved greatly the thermal efficiency of boiler, and the thermal efficiency is up to more than 85%.Have energy-conserving and environment-protective, the thermal efficiency is high, safe and reliable, stable, the advantage that applicability is strong.The manufacturing industry that can be widely used in colliery, factory floor, every profession and trade is produced heating, produces the industries such as heating, animal husbandry cultivation, grain medicinal material, agricultural avocation processing oven dry in agriculture green house of vegetables, winter.
