In early November, Luyi County, Henan Province Quality Supervision Bureau organized a safety inspection activities on the low pressure heating boiler factory in the area, ensure the safe use within the jurisdiction of the boiler in winter.
The main focus of inspection units use boilers to see through the following points:
First, the use of registration, maintenance, periodic testing situation.
Second, the establishment and implementation of the system and the rescue plan.
Third, if the boiler worker certificates.
Fourth, the operation of the boiler water treatment facilities.
To date, Luyi County Quality Supervision Bureau has complete supervision and inspection work on 11 units in the boiler, the inspection found problems and risks, monitor the instruction issued according to the law, clearly boiler rectification matter and time.
For different working pressures low pressure heating boiler factorys, to have a separate steam pipes and water pipes, respectively. If when a combination of the main steam pipe, the steam pipe to be fitted with high pressure apparatus and the automatic depressurization safety device that prevents the low-pressure side of the overpressure. When the water pressure does not exceed 20% of the maximum pressure, the system can feed water to the boiler feed water from the total.
Gas noise reduction methods for gas-fired boilers are mainly sound insulation, sound absorption and noise reduction.
This type of horizontal low pressure heating boiler factory was used on virtually all steam locomotives in the horizontal "locomotive" form. This has a cylindrical barrel containing the fire tubes, but also has an extension at one end to house the "firebox". This firebox has an open base to provide a large grate area and often extends beyond the cylindrical barrel to form a rectangular or tapered enclosure. The horizontal fire-tube boiler is also typical of marine applications, using the Scotch boiler. Vertical boilers have also been built of the multiple fire-tube type, although these are comparatively rare; most vertical boilers were either flued, or with cross water-tubes.
