Description
One. technical field
The invention belongs to a kind of simple in structurely, pilot flow combustion gas boiling water that the thermal efficiency is high and hot water two purpose boiler also can be made steam boiler in case of necessity.
Two. background technology
Under the promotion of China's energy-saving and emission-reduction policy, create conservation-minded society, certainly will to eliminate a collection of manufacturing cost height, complex process, heat exchange weak effect, pollute greatly, high product consumes energy.According to the existing energy resource structure of China, popularize that consumptive material is few, the product of energy-conserving and environment-protective plays crucial effects to the economic development of China.
Existing big and small Industrial Boiler and boiler for domestic are one of bigger equipment of China's energy consumption, and the steel of producing these equipment have also accounted for sizable ratio in total steel consumption the inside of China, therefore, reduce the boiler manufactured materials, reducing boiler energy consumption and discharge amount of pollution is the important measures of China's sustainable development.As: Chinese patent literature 98205908.6 discloses a kind of high efficient gas boiler.It has realized that volume is little, cost is low, do not have explosive sound during easy to use, igniting, flames of anger burning, advantage free from environmental pollution; This invention burner 3 be arranged on flue 2 below, igniter head 11 of igniter is formed by two at least, and be in respectively burner combustion tube 7 near.Efficient transducer 4 is made up of acclivitous comb 14, and comb is located in the flue above the burner, and its two ends are connected with water jacket 17; Flue is arranged in the housing 1, forms water jacket 17 between flue and the housing; This boiler is suitable for the usefulness of indoor heating and heat supply water, and the thermal efficiency can reach more than 85%.And for example: Chinese patent literature 200710092977.0 discloses a kind of condensing type highly effective gas displacement type water heater, this invention includes enamel inner container, anodic magnesium rod, smoke exhaust pipe, the flue sheet that stagnates, smokejack, the water heater heat-insulation layer, the support ring combination, outer casing upper cover, shell, the combination of shell lower cover, front shroud, the front shroud cover plate, cold water inlet, hot water outlet, fuel gas inlet, the temperature, pressure relief valve connection, burner, gas control valve, between enamel inner container and water heater heat-insulation layer the adverse current cover is arranged, adverse current cover upper end is connected with adverse current cover top cover, forms the adverse current chamber with the enamel inner container outer wall; Have the ponding dish to prop up seat ring in the support ring combination, the ponding dish props up the ponding dish on the seat ring; Also have the cover of backflow between adverse current cover and water heater heat-insulation layer, backflow cover lower end and ponding dish are with connecting, and the upper end has the cover of backflow sealing ring to be connected with the adverse current cover, with the outer wall formation back cavity of adverse current cover; Smokejack is in the outer casing frontispiece middle and lower part, leads to front shroud exhaust smoke hole on the shell, and the cover front upper that refluxes has mouth and smokejack to lead to; The outer wall of the water heater heat-insulation layer parcel adverse current cover and the cover that refluxes.
Three. summary of the invention
It is long and heat transfer rate is high and realize flow guide gas-fired boiler energy-conservation and the reduction steel consumption to the objective of the invention is to design a kind of heat exchange process.
Basic ideas of the present invention are: the high-temperature flue gas after the burning concentrates in together and enters from the outlet of boiler bottom plate that to carry out flow deflector between chimney and the recirculated water collapsible along Cheng Jiare, realizes making full use of of heat energy to reduce final exhaust gas temperature.
The technical scheme that the present invention takes is: a kind of pilot flow gas-fired water heating boiler, relate to by the boiler top board, boiler bottom plate, the water tank that shell surrounds, on water tank, be provided with water inlet pipe, boiled water pipe, hot-water line, on the boiler top board, be provided with evacuated tube, below boiler bottom plate, be provided with gas burner, it is characterized in that: have a chimney from water tank, to pass, the mouth that advances of chimney is positioned at the boiler bottom plate center, the outlet flue of chimney is positioned on the boiler top board, along the chimney direction circulating water pipe is housed at the one section chimney that is positioned at water tank, circulating water pipe up and down two ends is communicated with the alternate polylith flow deflector that is provided with on the outer wall of circulating water pipe after passing the wall of chimney with water tank.
Further scheme is: hot-water line is positioned on the boiler top board.
Further scheme is: the outlet flue of chimney is positioned at boiler top board center.
Further scheme is: chimney be shaped as circle, flow deflector be shaped as semi-annular shape, and the internal diameter of flow deflector equals the external diameter of chimney, flow deflector is provided with along the chimney circumferencial direction.Can reduce the processing and manufacturing difficulty like this.
Further scheme is: shell is surrounded by heat-insulation layer outward.
Further scheme is: boiler bottom plate is downward arcwall face.
Flow deflector can be arranged a plurality of according to the length of circulating water pipe, realize that repeatedly water conservancy diversion and flue gas are folding, increases the flow process and the disturbance of flue gas with the method, realizes further augmentation of heat transfer effect.
Burner is annular firing as far as possible, and the flame that is produced does not directly enter in the chimney, but gathers to the centre around boiler bottom plate, and the flame that makes that like this can be artificial obtains diffusion, increases the area of flame, and it is long-pending to strengthen radiation heating-surface simultaneously.
Because the present invention is simple in structure, each parts coefficient of expansion is good, and the intensity height is equally applicable to the application of bearing hot water boiler and steam boiler.
Advantage of the present invention is: because heating power makes progress and the downward principle of cold gravity, internal water forms Natural Circulation to circulating water pipe under heat exchange, effectively strengthened the coefficient of heat transfer in heating process.Simple structure, lower cost, the heat transfer type of reinforcement has been captured the short and low shortcoming of heat transfer intensity of conventional boiler heat exchange process, and has realized advantage energy-conservation and the reduction rolled steel dosage.
