Product Description
heavy oil boileris designed to comply with the provisions of the hot water boiler Safety Technical Supervision Regulations (1997 Revision).
The boiler model WNS7-1.0/95/70-Y (Q), is a fully automatic Horizontal internal combustion three pass fuel (gas) packaged boiler, wet back structure, the waveform furnace gall backhaul, by threaded pipe constitutes the second return, light smoke tube constitutes the third return trip. Boiler is equipped with a complete automatic control devices and safety protection devices; hot water temperature automatic control and over-temperature alarm; the boiler automatic ignition, and the burner fire automatically adjust the flame protection; ensure the safe operation of the boiler.
The products of fuel oil or gas. Fuel ejected from the burner, electronic ignition rod lit, slightly positive pressure within the internal furnace burning, high temperature flue gas by burning ember room turning into the second return 180 ° and 180 ° turn front smoke box into the third return trip Finally, after the passage of the smoke box by the chimney into the atmosphere.

Third, the product structure Introduction
The boiler boiler body, base, packaging and insulation, platform escalator, instrument valves and accessories before the smoke box, after the smoke box, electronic control systems and other components.
The the boiler body under the home furnace, smoke pipe and furnace gall symmetrical layout on the overall structure of the form of the drum welded barrel Ф2400 × 12 Ф2400 × 16 front tube plate group. First return for the waveform furnace, the group from the the three waveforms furnace and two tapered internal furnace welded waveform furnace gall to Ф1100 10. Waveform furnace tube structure, both to increase the heat transfer area, increase the rigidity of the furnace tube, also meet the internal furnace heat of free expansion; the burning ember room by Ф1700 × 18 before the cylinder and the inner, Inner tube plate assembly welding made. Form of a wet back, avoid high temperature flue gas erosion on smoke box directly to improve the reliability of the boiler operation; second return 219 Ф51 thread smoke tubes. Threaded pipe can be greatly enhanced heat transfer, which can reduce the heating area, boiler compact structure, save steel; constitute a third return trip by 154 Ф51 light tube. Lower third return of the temperature of the smoke, the smoke tube with a light tube, compared with the threaded pipe, little effect on the heat transfer effect, it can greatly reduce the flow resistance.
Front and rear smoke box with integral smoke box, split smoke box door on the smoke box, the form of good integrity, beautiful, generous, open repair is also very lightweight.
The the factory chimney height of 12.9 m configuration, the user shall be approved by the local environmental protection department the requirements of the environmental impact report to determine the actual height, but shall not be less than eight meters.
Safety valve, auxiliary equipment and control instructions
The boiler is equipped with a of A47H-1.6C spring inching safety valve (DN50) two.
The burners are equipped with imported burner, beautiful appearance, high degree of automation, from the pre-purge, ignition, fire automatic conversion to automatic shutdown and flame protection, can achieve automatic control.
Water supply pump JGGC12.5-15 × 11, the boiler automatic replenishment.
