boiler agent bubbling fluidized combuster

Wuhan Yu Dahua Group Co., Ltd. is a cotton based, weaving, knitting and textile car decoration installation in one of the cross-industry, diversified and comprehensive export-oriented enterprise groups. 2017, the Group expanded production scale textile processing, the number of new production lines, the Group's original steam boiler agent bubbling fluidized combuster can not meet the growing demand of orders in urgent need of a new steam boiler purchase. When selecting vendors steam boiler, the boiler output device side fast sustainable high quality steam attracted, decided to cooperate with the fast boiler. Fast art by side to the user site needs analysis, to provide two integrally condensing gas steam boiler (WNS4-1.25-Y.Q).

Non-staff are not allowed to switch the various valves in the boiler agent bubbling fluidized combuster room, the smoke damper and electrical switches, undocumented fireman, water quality laboratory personnel are not allowed to operate separately.

Former Chenzhou steam boiler agent bubbling fluidized combuster installer to install steam boilers, should write "to start installing the application report", carrying at least including the boiler management authority for all of the following information to the steam boiler earthly boiler installation approval process, before it can start after approval: ① steam boiler installation of the original license; ② steam boiler installation application starts report and installation program; ③ steam boiler certificate material; ④ steam boiler room layout drawings and plane steam boiler room planning material; ⑤ installation company vocational certificate construction workers. Former steam boiler installation, the installation company should also carry approved "to start installing the application report" to everyone earthly quality technical inspection authority Steam Boiler and Pressure Vessel Inspection Branch signed the "quality of the installation agreement responsibility" by the laboratory steam boilers the quality of the installation is completed supervision.

Professional boiler agent bubbling fluidized combuster water wall boiler worker should master knowledge of the water cycle: boiler water wall is called "water wall tube", also called "riser pipe." Generally perpendicular to the wall surface is laid on the furnace wall. Is the main part of the boiler the heated water wall, which consists of several rows of steel tube, located in the boiler furnace four weeks; internally flowing water or steam, the heat of the flame to accept external boiler furnace. The main furnace heat absorption of the radiation of the high-temperature combustion products, wherein the working fluid for upward motion, heat was evaporated.

Fluidized Bed Article about Fluidized Bed by The Free

The change of a static bed to a fluidized bed occurs when the velocity of the fluidizing agent is such that the hydrodynamic pressure of the flux P balances the force of gravity G acting on the particles. Further increase of the velocity leads first to an initial expansion of the layer, with constant hydraulic drag, and when P > G the particles begin to separate from the layer.
