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.
This kind of boilor is very efficient in firing matetials, such like rubbishs, coal-water mixation, etc. And the price is cheaper than others. International standard
The headers of boilers include water-cooling hinders of boilers proper, economizer hinders, superheater hinders, etc. They function for gathering, mixing and redistribution in boiler systems. In structure, they include end cover hinders or necking hinders. In manufacturing, the key of end cover hinder is welding. Since by manual arc welding, the weld joint is single-side welding without quality guarantee at the ends. In addition, due to large welding workload, frequent return for repair and long working period, it became the throat process of the whole hinder production. When making hinders of the style, we adopt advanced production technique, complete large equipment and mature technology, especially automatic submerged arc welding between hinders and end covers. Such welding methods have high manufacturing efficiency, good quality, beautiful welding shape, safety, reliability, etc.
The circulating fluidized bed boiler headers collect and distribute steam or water from or to a series of smaller pipes or conduits. They are made of carbon or ferritic steel, generally of the same grade as the piping systems. Unlike piping systems which are usually butt welded and bent, the boiler spare part headers are straight. Features 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 safet Application Save energy high pressure welding manifold headers for distributionrs collect and distribute steam or water from or to a series of smaller pipes or conduits.Manifold headers are made of carbon or ferritic steel, generally of the same grade as the piping systems. Unlike piping systems which are usually butt welded and bent, headers are straight.
Zg boiler dhx type circulating fluidized bed boiler is an improved product based on the advantages of the circulating fluidized bed boilers at home and abroad. By reducing the circulation ratio and optimizing the key components and parts, the problems including boiler abrasion, the coking and blocking in the feedback section, high original discharged dust consistence and difficult slag discharge have been overcome. All the features make the boiler structure is more rational, performance is more excellent and the operation is more secure. Fumigated wood box, u-steel, steel frame reach to sea transportation requirement.

The fuels of this boiler is with broad adaptability, so many kinds of coal is suitable to supply stable and efficient heat. During the operational process of the boiler, it is easy to achieve high burning efficiency in the condition of not changing burning equipment when the coal is changed. 2). Circulating fluidized bed boiler is radically different from other boilers on the burning system. Its burning system consists of burning room, material destination and material returner. The high heat material enters the material returner together with the airflow, and the material collected will enter the material returner and then returns the burning room. This is called circulating burning which increase the burning efficiency greatly. 3). This boiler is with a wide range and high speed of load adjustment. 1mw-660mw
CFB series energy saving boiler water wall that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Membrane water wall are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the steam boiler. welding heat exchanger industrial boiler membrane water wall are membrane walls that are made of tubes welded together with or without a strip of metal in between.
