Cfb Boiler Header

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.

The boiler headers have water wall header, superheater header, economizer header and so on, it acts as collection, mixture, re-distributing working medium, as the structure, it can be classified as the end cover type( end enclosure) and necking down type. 1. Strength calculation report with applied materials information; 2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod; 3. 100%X-ray inspection report (welding seam): to ensure the quality of the entire boiler; 4. Hydraulic test report: ensure the standard working pressure and safety

The boiler headers have water wall header, superheater header, economizer header and so on, it acts as collection, mixture, re-distributing working medium. From the structure, it can be classified as the end cover type (end closure) and necking down type. Steam header is the main equipment of boiler for allocating the steam to the all pipe. Steam header is a Pressure Vessel ;the main function is to allocate steam.So steam header has many valves to connect the boiler main steam valve and steam distribution valve,and make the steam into anywhere. 1. Strength calculation report with applied materials information; 2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod; 3. 100%X-ray inspection report (welding seam): to ensure the quality of the entire boiler; 4. Hydraulic test report: ensure the standard working pressure and safety

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.
