The present invemion sciâtes to a sfe&sn generator vrite a coïnfeiiosï cfesaïbet, at feast: 00« Site gas duet and a boiler assembly, »herein each holier astembfy comptai plurality te; lt«iy$$S8i 'itfemMÿ designed steam IblferS: with s closed water circuit, each of said steam bdfc having a pipe eOpsSïÂiott which comprises at least otterisef pipe, guided tefbogb the combustion chamber a steam discharge plpm ia downpipe and a: connecting pipe iolrilmg tom the tetter to the riser pipe,:

Bmeé the beginning of the: Industrial revoistloh, Öre getfef sillon: of steam: hits feèett M essentia! requirement for numerous industrial installations. Despite «tarty years' experience In the handling of steam generators, their operation eontlnties to be hound op with risk, sts.ee dangerous steam explosions can occur if there Is a failure to bike doe ears or in the event of technical failure* The: erection, operation and maintenance of steam generators are consequently subject to strihpnt official replÄgts, such as fer example in Austria die "Bressmo Equipment Control Order" (DGÜW-V), the "Ordinance goveremg the Erection and Operation of Steam Boilers* (ABV) and the "Daw governing Steam Boiler Operation" (BfCBOf

The risk potential of a steam boiler plant depends primarily on the volume of the pressure vessel and on the maximum. operating pressure, wherein the plants: ean he classified into various risk classes on the basis of specific features, ter example the: pressure content product (product of operating pressure times volume).

Extensive and cost-intensive regulations In respect often initial operating test, regular operating tests, nature of momtpring, review dotes and tsositoring measures (measures as part of recurring Investigations or examinations) and dpeuptontelon: In respect thereof have to he complied with for steam boilers, pressure vessels or pipelines vrillt a high risk potential.

Elates whit a tew risk potential are excluded from these stringent regulations and, amongst other things, have the advantage that for «sample, the: monitoring can,be carried out hy die operator itself, Ihessure vessels with a low risk potential include for example steam: boilers with a risk: of overheating or pressure vessels with a risk of pvérhestmg, the pressure content: product whereof Is less than 2ÔD fbar x I), or, if they comprise pipes with nominal widths up to and including a maximum of DM 32, the pressure content product whereof is teas than 35Ö flat x I]. 'these inehMte for dxampte stwcaled ‘'high-speed steam generators", High-speed steam pnerstorsi, however, deliver only small quateitteS: of Steam usually of low quality and are therefore unsuitable ter many appHcanons.

Steam gertemtors of tee type tebtekmed at the outset are known ter or PB-465 425, these eeteodimenis are conventional steam boilers with apiumlsty ofwstpeirenks.

There: Is howe ver a need ter low-cost steam generitem? with a low risk potmtial, whteh can alp pnerate large quantities of high-quality steam. This reduces considerabiy the cost of steam generation, with at the same time maximum possible opeteiioha! safety.

Tie present invention solves Btfeptebtete by a steam genmÄr of the type mentioned at tie outeet, wherein each of the steam boilers is constructed with pipes up to and including a maximum of DM Î2 to achieve a Sow risk potential In accordance with § 5 of the Austrian Pressure Equipment Control Order" (DGÜW-V), wherein the pessmo potent produef fp x: V): amounts to less than 33ö|bsr x I|, The qnanity of steam that can be pnerated is not increased by an increase in tee boiler volume and maximum pressure, but rather is detetmtned by tee aÉÂaf are opifesd chamber. Dependmg oc the requirement, the «tsars hollers can be designed: as nnniml-circalatxon. forced-mrculation or fereed-Oow boiser«. Forceddliw boilers eon for ex&mpte «nuptiaepassed through she «oj«b»srksß chamber. 1s an embodiment of the invention, a beat exchanger for feed sorter preheating can preferably he disposed is? the One gas channel. This improves rise energy efficiency of the system.

Tie heat exchanger can admtdageensty comprise tubes, the ttsbe axes whereof are disposed essentially is tie same plane as die pip axes of the steam boiler. Ib is enables an extremely compact desip of the steam boiler and beat exchange?, wherein the tabes of the heat exchanger can tor example be disposed issip a bbme fermed by fee riser pipe, steam discharge pipe, downpipe and; cesmectiag pipe, A plurality of heat exchangers, disposed fiat beside one another, of a plurality of flat sfeam: bpiiers disposed beside one tmofesr can advantageously he disposed In the same floe gas duct , Baffle plates In the tine gas duct can increase the bow path of the flue gas is she region of the heat exchangers and tints Improve the heat transfer, I» a ferfeer advantageous embodiment of the invention^ at least one further steatb belief can be provided for cooling the combostlon chamber wails, the riser pipes of Md kesfe boiler being disposed lb lie region of the combustion «tomber wails. The riser pipes of streb edmbhstlöh clamber wall steam bolters can be disposed cage-dike around the combustion clamber waif for bxfehffe in dm regions wtoà$: »& riser lim of the first-mentioned;, Identically designed steam boilers are: provided,, so feat the wail is cooled in all regions and is used Ibf stops generation. Tils Improves the steam yield and the enetgy efficiency of fee system and at fee same time ensures cooling of the combustion chamber walls.

The steam removal lines leading; away feme fee respective Steam removal connection^ ofife» steam boilers can emerge into a steam col looting line. This is possible, slice fee; Steam collecting line, ont of safety cotssldemdons, is no- longer included in fee volume: of tie stesnn Ipilers, À plurality of steam boilers, dm steam whereof is conveyed into a common steam collecting Hoe, are not therefore to be considered as | total volume, but rsfeer each individually for the rating of fee safety criteria.
