Abstract
The utility model relates to a fully automatic gas-fired fuel-oil atmospheric water heating furnace, which comprises a fuel-oil engine 1, an internal furnace 3, a furnace casing 2, a smoke discharging cylinder 15, and a water jacket formed between the internal furnace and the furnace casing. The utility model is characterized in that the water jacket formed between the internal furnace and the furnace casing is divided into an upper water chamber and a lower water chamber through a baffle plate 6. A disc type water fire pipe 4 is arranged in the middle of the internal furnace. The water inlet of the disk type water fire pipe is communicated with the lower water chamber, and at the upper part of the utility model, the water outlet of the disc type water fire pipe is communicated with the upper water chamber. The upper and the lower water chambers are respectively communicated with a hot water outlet 12 and a cold water inlet 8. The fuel-oil engine 1 is arranged on the cover plate 16 of a furnace smoke box 14. The flame front of the fuel-oil engine is positioned on the central part above the internal furnace. Because of the structure, the utility model has the advantages of small size, manufacturing cost and transportation cost reduction, convenient installation and maintenance, and high thermal efficiency. Compared with the energy consumption of the same model furnaces produced by the home factories, at least more than 5 percent of energy is saved.
Description
The utility model relates to vertical boiler, particularly a kind of fully automatic fuel-oil gas normal-pressure hot-water boiler.
The disclosed a kind of vertical normal-pressure hot-water boiler of Chinese patent ZL95203817.x, structure comprise the intercalated water sleeve that forms by in the middle of shell and the flue, and tilt to be installed in the convection tube in the flue.There is the deficiency of the following aspects in this vertical normal-pressure boiler:
1. be coal-burning boiler, exist dust big, labour intensity height, the defective that energy resource consumption is big;
2. convection tube tilts to be installed in the flue, complex structure, and manufacturing, installation and maintenance are complicated;
3. the thermal efficiency is not high.
Though there is oil-burning gas-fired boiler in the prior art, have that volume is big, manufacturing cost is high, burning just can reach the deficiency of duty for a long time during use.
The purpose of this utility model is to provide a kind of volume little, rational in infrastructure, is convenient to make and maintenance non-environmental-pollution, the automatic fuel gas fuel oil normal-pressure hot-water boiler that thermal efficiency height, security performance be good, exert oneself big.
Above-mentioned purpose of the present utility model is to realize that by such technical scheme promptly a kind of automatic fuel gas fuel oil normal-pressure hot-water boiler comprises oil-burning machine, flue, furnace shell, the water holding jacket that forms between flue and the furnace shell; It is characterized in that: the water holding jacket that forms between flue and the furnace shell is separated into lower header by dividing plate, disc type extreme misery pipe places the centre of flue, its water inlet is communicated with lower header, and its delivery port is communicated with upper tank on top, and last lower header is communicated with delivery port and water inlet respectively; Combustor is installed on the boiler uptake cover plate, and its flame front is positioned at center, flue top.
Said structure of the present utility model can further specify by the non-limiting embodiment that accompanying drawing provides.
Accompanying drawing is the utility model example structure schematic diagram.
Referring to accompanying drawing: automatic fuel gas fuel oil normal-pressure hot-water boiler among the figure comprises oil-burning machine 1, flue 3, furnace shell 2, the water holding jacket that forms between flue 15, flue and the furnace shell; It is characterized in that: the water holding jacket that forms between flue and the furnace shell is separated into lower header by dividing plate 6, disc type extreme misery pipe 4 places the centre of flue, its water inlet is communicated with lower header, and its delivery port is communicated with upper tank on top, and last lower header is communicated with hot water outlet 12 and cold water inlet 8 respectively; Combustor 1 is installed on the cover plate 16 of boiler uptake 14, and its flame front is positioned at center, flue top.
In the present embodiment, the top of furnace shell and flue is connected with upper cover 13, furnace shell the bottom be connected with low head 9, the bottom of the water holding jacket lower header that forms between flue and the furnace shell has blow-off pipe 11, upper tank is equipped with liquid level gauge 18, exhaust-valve 17 and return pipe 5, the bottom of flue is connected with the interior end socket 7 of flue, and boiler bottom is supported by skirt 10.Extreme misery pipe 4 in the present embodiment is the double end coil pipe.Boiler can adopt alumina-silicate refractory fibre blanket or coating to make external thermal insulation, and the thermal efficiency is higher.
The utility model is realized supplying water according to water level by the automatic control section control of its outside automatically.
The course of work of the present utility model is such: promptly boiler in use, the flame of centre of combustor is passed by the center of disc type extreme misery pipe, the bottom of end socket 7 and extreme misery pipe in the direct internal combustion furnace, return flame or heating power by the gap between coil pipe and furnace wall to rising, can be to the outer surface and the furnace wall heating of all extreme misery pipes, water in formula water holding jacket and the extreme misery pipe is fully heated, and flue gas is discharged by chimney 15.
The utility model is owing to described structure has following advantage:
1. rational in infrastructure, volume is little, saves manufacturing cost and freight;
2. installation, maintenance is convenient, and floor space is little;
3. thermal efficiency height, energy savings, energy-output ratio is the same model boiler contrast that domestic manufacturer produces, energy savings is more than 5% at least.
4. performance is safe and reliable, non-environmental-pollution.
The utility model can be widely used in the place that bathroom, hostel, hotel and school etc. need heat supply to supply water.
