1.4 Preparation for foundation
According to foundation sketch, well prepare the install foundation for boiler and
pre-fabrication plate of ladder.
1.4.1 After boiler arrive in site, check all parts according to the packing list. Re-check the
completeness of boiler set according to the general drawing. Check whether there are any
damage and deformation during transport the large boiler components.
1.4.2 When unload the boiler large components, can place 8 to 10 piece tubes below the steel
plates of two sides of bedplate, pull it with steel rope and make the boiler large component
move slowly on the rolled tubes. At this time should pay attention to the location for placing
steel rope, insure no any destroy to all boiler parts.
②
Install for boiler large components
After the boiler is placed on the two strip foundation, it will has some incline, the fore end
of axis centerline will higher than back end for about 10 to 25mm (according to different
foundation drawing). It is very convenient for blowing down.
After check the level to boiler, add cement to boiler bed support and two wall foot.
③
Installation for chimney
The chimney height should be according to the user
’
s requirements.
3.1 While assembling chimney, add asbestos rope between flanges, check the perpendicularity
of chimney through hanging perpendicular line, if there is error, can adjust it by backing piece
at the connecting location of flange.
3.2 If use steel cable, it can be strained by screw. Three pieces of steel cable is uniform
distributed around a circle, should pay attention to keep three steel cables have the same strain
force roughly.
④
Installation for pipeline, valves and instruments
4.1 Install the pipeline, valves and instruments according to drawings. Water pump is
connected with water tank, if user has additional requirements, can provide spare water pump.
4.2 Safety valve must be assembled after hydraulic testing and connected to the tube for
dumping steam so as to dump the steam to safety place. The section area of dumping steam
pipe should not less than the section area of the outlet of safety valve, the pipeline should be
arranged to minimize the resistance of blow down and keep draining water smoothly.
4.3 The blow down pipe should be connected to blowing down tanks or other safety place. In
order to avoid happening the accident of moving or scald, the pipeline must be fixed.
4.4 All steam pipeline except for main steam valve should be assembled by user, there is at
least one elbow at the main steam pipeline, otherwise should add telescopic tube. The pipeline
must be insulated.
4.5 The pipes for draining water at the lower position of water level and water level automatic
controller must be connected to safety place. The cock of water level gauge can rotate quickly
and has no water leakage. The water level gauge must be assembled with lighting installation.
4.6 The dial panel of pressure gauge should be marked with red line to indicate the highest
allowable working pressure. The cock of pressure gauge should rotate quickly and have no
water leakage. The drainage of water should be very smooth. The insulation of pressure gauge
is forbidden.
⑤
The other parts installation
5.1 The oil pump unit should be installed on the bedplate (if oil-fired pump is installed inside
burner, it means oil-transferring pump).
5.2 The electrical control box should be installed at the position that is convenient for
observation burner.
5.3 The burner will be connected with electrode nozzle of boiler.
⑥
Hydraulic testing
After finishing the install of boiler pipeline, valves, instrument and so on, check and clean
the inside surface of boiler, close manhole and hand-hole, conduct hydraulic testing according
