In, the outer wall of smoke-fire-tube (3) is uniformly provided with 16 radiating fins (4), radiating fin (4) is set with smoke-fire-tube (3) axis parallel
Put, and cover smoke-fire-tube (3) all length；And the relative radiating fin (4) in smoke-fire-tube (3) both sides is along by smoke-fire-tube (3) axle
The plane of the heart is arranging；In smoke-fire-tube (3), width radially is the 1/11 of smoke-fire-tube (3) internal diameter to side radiating fin (4).On
Stating concrete setting can make to reach optimum balance between heat exchange efficiency and manufacturing process.
The directly-heated hot-water boiler of the present invention, fully, the thermal efficiency can reach more than 97% (high heating value) for heat exchange；Energy-conservation: flue gas
Exhaust temperature below 50 DEG C, efficient utilization heat energy；Environmental protection: co, no, no in flue gasxContent reaches " Atmosphere of Beijing pollutant row
Put standard ".Boiler integrally adopts stainless steel structure, and temperature equilibrium, and in water, calcium, magnesium plasma cannot separate out, non-scaling, so
Do not need to carry out sofening treatment to water quality.Individual cavity, compact conformation are adopted on this boiler structure, saves material, its weight phase
When in the 25%-35% of plain cylindrical furnace.Shared space is equivalent to the 55% of plain cylindrical furnace, saves space.Application place
Supply thermal recovery including school, factory, outdoor bathing place, hotel, hospital, nursing house, enterprises and institutions, stadiums, warm water swimming pool, dormitory etc.
Warm project.The directly-heated hot-water boiler of the present invention obtains under conditions of water temperature is less than 95 DEG C, so water temperature to be kept under strict control.Controlling system
On system, identical with plain cylindrical furnace, can be using switch board or integrated circuit modules to burner, water temperature, liquid level and security alarm system
System is controlled, high degree of automation, simple to operate efficient, thus reducing labor intensity.Fuel adopts clean energy resource (as natural
Air-liquid liquefied oil gas, biogas) it is optimal.
In addition, the technical advantage of the directly-heated hot-water boiler of this embodiment also includes:
1st, smoke-fire-tube (3) is placed in water, and is fully contacted heat exchange with water, and polylith radiating fin plate (4) increases heat-transfer surface simultaneously
Long-pending, it is compared to the smoke-fire-tube of comparable size, heat transfer more quickness and high efficiency.
2nd, the flue gas rising carries out pre- heat exchange by packing area (8) and water inlet (13) water, by the delayed heat in flue gas
Amount exchanges, and exhaust gas temperature is less than 50 DEG C, and compared with 180 DEG C of plain cylindrical furnace exhaust gas temperature, stove effect is significantly lifted.
3rd, spiral nozzle (9) can eject water in flue gas, reaches the purpose of heat exchange.
4th, water inlet is distributed evenly in filler top by inlet distribution device (10), reaches the effect at the uniform no dead angle of heat exchange.
5th, the flue gas after heat exchange can contain a small amount of water vapour, by vapor mistake when by heatproof filter cotton plate (11)
Leach, after condensation, supplement back reservoir chamber (15).During boiler operatiopn, water loss is few.
To sum up, the directly-heated hot-water boiler efficient utilization heat energy of the present invention, fully, flue-gas temperature is low for heat exchange, greatly improves
Stove effect, internal structure is compact, and heat exchange efficiency is high, heats up rapid.
Although, the present invention is described in detail, at this above to have used general explanation and specific embodiment
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention, belong to the scope of protection of present invention.
