Abstract

The present invention provides an oil and gas fired boiler having an annular combustion chamber. The oil and gas fired boiler is provided with a shell, a furnace and water pipes. A plurality of combustion engines are configured at the periphery of the shell, and the furnace is arranged in the center of the shell. The annular combustion chamber is positioned at a lower portion in the furnace, and the water pipes are positioned at an upper portion in the furnace. The annular combustion chamber is communicated with the upper portion in the furnace to form a smoke flow channel for combustion heat exchange. A space between the furnace and the shell and spaces inside the water pipes form water evaporation upstream channels. The boiler is compact in integral structure, simple in geometrical shape, small in size and high in strength, heat exchange is convenient and sufficient, and thermal stress of the furnace is uniform. The advantage that no solid waste residue is discharged from an oil and gas fired boiler is fully performed, and requirements on fast assembly, modularization and integral assembly of a middle-large sized oil and gas fired boiler can be substantially satisfied. The history that an oil and gas fired boiler uses a structure of a coal fired boiler will be ended. The oil and gas fired boiler having the annular combustion chamber is a boiler according with oil and gas fired characteristics.

Description

A kind of annular combustion chamber oil-burning gas-fired boiler

Art

The present invention relates to a kind of boiler, be specially a kind of annular combustion chamber oil-burning gas-fired boiler.

Background technology

China is energy importation big country, and especially appearance grows at top speed by Imported gas and consumption.Numerous coal-burning boiler causes serious environmental pollution, also impels China Development of Coal liquefaction to gasify, realizes the clean utilization of coal.Therefore, oil-burning gas-fired boiler technology is the key realizing the transformation of this energy consumption structure.

Current widely used oil-burning gas-fired boiler mostly is middle-size and small-size pan shell type multitubular boiler.Pan shell type multitubular boiler can not meet the requirement of medium-and-large-sized oil-burning gas-fired boiler.Generally believe that in the industry the developing direction of medium-and-large-sized oil-burning gas-fired boiler is water-tube boiler.Although also have a small amount of water-tube fuel oil gas fired-boiler now, these boilers majority adopts upper lower drum and evaporation convection Pipe bundle structures, cause Site Welding difficulty and workload very big.And this structure can not meet the requirement of medium-and-large-sized oil-burning gas-fired boiler fast-assembling, modularization, overall package.Medium-and-large-sized water-tube fuel oil gas fired-boiler is that bulk parts dispatches from the factory always, Site Welding.

Make a general survey of boiler development history, boiler originates from the water with being contained in the interior fiery heating kettle of stove, and then develops into the multitubular boiler that shell wraps up flue, finally occurs pot and stove water-tube boiler arranged apart.The advantage of multitubular boiler is compact conformation, but evaporation capacity is little, steam pressure is low; Though water-tube boiler huge structure, evaporation capacity is large, steam pressure is high.It should be noted that: these two kinds of boilers are all coal-burning boilers, and present oil-burning gas-fired boiler is all use coal-burning boiler.Can say so, also there is no real oil-burning gas-fired boiler now!

The oil-burning gas-fired boiler characteristics and advantages the most outstanding relative to coal-burning boiler is just do not have solid residue to discharge, as long as provide the problem of environmental pollution that can ensure that the clean-burning combustion chamber of fuel-firing gas-firing and flue gas heat exchange passing away just can perfectly solve coal-burning boiler and face.Oil-burning gas-fired boiler best-of-breed technology route carries out boiler one, water pipe heat exchange.Namely draw the technology elite of existing multitubular boiler and water-tube boiler, with brand-new structure and remarkable performance, start the real oil-burning gas-fired boiler technology New Times.

Summary of the invention

The object of the invention is to configure combustor outward at shell, in shell, lay flue, in flue, arrange water pipe and annular combustion chamber, form a kind of annular combustion chamber oil-burning gas-fired boiler.

To achieve these goals, the solution of the present invention is: its structure comprises the outer pipeline with flue inner combustion chamber of shell, flue, combustor, connection shell, is communicated with smoke discharge tube, water inlet pipe, vapour-discharge tube, the heat-insulation layer of shell outward and in flue.It is characterized in that: described shell is uprightly arranged, the outer surrounding of shell configures multiple combustor, and in shell, central authorities settle flue.An outlet being communicated with the smoke discharge tube outside shell and in flue is arranged at shell top, and shell bottom has outside multiple connection shell and the conduit entrance of flue inner combustion chamber.The flame playpipe of combustor inserts combustion chamber through being communicated with shell pipeline that is outer and flue inner combustion chamber.Be communicated with outside shell and fix flue in shell with the pipeline of flue inner combustion chamber, the smoke discharge tube be communicated with outside shell and in flue.Shell bottom arranges water inlet pipe, and shell top arranges vapour-discharge tube.Flue bottom be two with end concentric drums.Flue bottom outer cylinder is higher than flue bottom inner cylinder.In the inner cylinder of flue bottom, upper end flatbed horizontal is closed.Between flue bottom inner cylinder and flue bottom outer cylinder, upper and lower side is all closed with flatbed horizontal, and upper end is as the criterion with flue bottom outer cylinder height, forms the annular combustion chamber that is communicated with flue internal upper part space.In the inner cylinder of flue bottom upper end dull and stereotyped with have the many parallel water pipes being communicated with two ends between flue upper surface.Parallel water pipe outsourcing one connects the flue top cylinder of flue upper surface and annular combustion chamber upper surface.Space in flue top cylinder, between parallel water pipe forms flue gas flow pass.Shell outer surface parcel heat-insulation layer.

Described water inlet pipe is arranged because boiler purposes is different and different with vapour-discharge tube, and fired gas-fired hot water boiler water inlet pipe is arranged on shell top, and outlet pipe is arranged on above annular combustion chamber.

The invention has the advantages that: one is that shell wraps up flue completely, and boiler compact overall structure, geometry are simple, volume is little, intensity is high.Two is that flue is immersed in water completely, and flue surface and pipe inner wall are all heating surfaces, and heat exchange is fast abundant, and flue thermal stress is even.Three is that combustion chamber volume is subject to shell restriction little, and height-width variable range is large, can adapt to the different requirements of various uses boiler.Four is that rolled steel dosage reduces in a large number relative to existing multitubular boiler and water-tube boiler, and manufacture difficulty significantly declines.Substantially the requirement of medium-and-large-sized oil-burning gas-fired boiler fast-assembling, modularization, overall package can be met.Five is that the manufacturing cost of this boiler and operating cost all significantly reduce than existing multitubular boiler and water-tube boiler, has the potentiality extensively promoted the use of.
