Brief Introduction of the CFB Boiler
The circulating fluidized bed boiler is a high pressure, single drum, steel structure and natural circulation boiler. The arrangement for the integrated boiler is adopted. Rectangular section of the combustion is adopted for the boiler. The membrane wall construction is arranged for the four sides walls of the furnace and enclosure of the rear pass. Water-cooled platen and secondary super-heater are arranged in the furnace while abrasion resistant refractory is lined in the emulsion zone at the lower part of the furnace to protect the furnace from erosion in operation. The super-heaters are divided into SH1, SH2 and SH3. Convection super-heater, economizer and horizontal tubular air pre-heater with primary and secondary airflow separators are arranged in the rear pass in sequence.
Two hot or steam-cooling cyclones with U type loop seal is arranged between the furnace and rear pass of the boiler. The cyclones are lined with refractory to assure reliable operation. Anti-explosion buck-stay and expansion center with non-metal expansion joint are arranged for the boiler to solve the tri-direction expansion problem.
Technical Features of the Boiler
* The design of the advanced water-cooled grid with even distributed air, large bell type nozzle, reasonable resistance and no blocking makes the boiler long service life ;
* Large width-to-depth ratio of the furnace to facilitate the secondary air passing through and being mixed ;
* High efficiency heat insulation cyclone separator is adopted ;
* Stable and reliable operation and high efficiency insulated or air-cooled cyclone ;
* Self equilibrating U type loop seal for returning the circulating material to make the control simple and reliable ;
* Three stage super-heater arrangement with the secondary super-heater in the furnace to improve the radiant characteristic of the super-heater efficiency ;
* Spray type de-super-heating is adopted to get fast de-super-heating reliably and safely ;
* Tubular air pre-heater with the primary and secondary air separate arrangement.
G_ Pulverized Coal Fired Boilers
Single drum, single furnace, natural circulation pulverized coal fired boiler is regularly arranged with equilibrating ventilation, solid removal, all steel suspension structure, all welled membrane walls, control damper at the back passes. Platen super-heater, end super-heater and low temperature super-heater, economizer and air pre-heater are arranged along with smoke flow process in sequence.
Technical Features
1. The unit is equipped with tilting corner nozzles for a tangential firing system to keep the air dynamic field inside the furnace without tilting
2. The furnace is optimally designed with proven structures proper arrangement and thermal parameters. A certain control margin are reserved sufficient to ensure complete combustion, high thermal efficiency , safe and stable operation
3. The thick-light patent is adopted for the primary air to allow easy firing and anti-sintering
4. The damper structure makes it a nice appearance
5. Three stages arrangement for super-heaters and two stages of water spray de-super-heating.
6. Tubular air pre-heater with the primary and secondary air separate arrangement.
Auto- castings and auto-machined parts.

Membrane water-cooled wall pipe panel welding production line is used for the fabrication of all specifications of pipe panel products, which is composed of flat steel finishing and cutting machine, pipe polishing and rust removing machine, pipe panel welder, in-row pipe panel bender and so on.
Brief introduction
This welder is composed of main machine and corresponding corollary equipments, which is used for welding multi-pipe and flat steel into pipe panel in different width. Adopting double-sided multi-welding torch groups, mixed gas shielded welding technology, with the advantages of high efficiency, reliable quality, good seam shape, advanced technology.
Technical character
4 heads, 8 heads, 12 heads, 20 heads boiler membrane wall pipe panel welder and its corresponding corollary equipments can be supplied according to user requirements. On the basis of introducing Japan Mitsubishi MPintroducing Japan Mitsubishi MPM welding technologyM welding technology, this machine is modified as changing DC speed-adjustment into frequency conversion, Full localization has been realized. Simultaneous double-sided mixed gas shielded welding is available by adopting pulse inverter power supply with the advantages of little deformation, good seam shape, with quality completely meeting the technical requirement for the fabrication of boiler membrane pipe panel. This machine has completed the manufacture of 200, 000KW, 300, 000KW, 600, 000KW boiler membrane wall pipe panel satisfactorily through the productive practice of boiler factory.
