Rota­ry kiln

Low-main­ten­an­ce and reli­able in ope­ra­ti­on, rota­ry kiln tech­no­lo­gy enab­les envi­ron­ment­al­ly friend­ly ener­gy genera­ti­on. The poten­ti­al of this con­cept deser­ves to be ful­ly exploited.

Decen­tra­li­sed ener­gy concepts

Agri­cul­tu­re, indus­try and muni­ci­pa­li­ties are facing incre­a­sing pres­su­re to recy­cle by-pro­ducts and was­te effi­ci­ent­ly. We see oppor­tu­nities abo­ve all in the high poli­ti­cal and social expec­ta­ti­ons. Decen­tra­li­sed recy­cling con­cepts are incre­a­singly com­ing to the fore and offer noti­ce­ab­le reli­ef. In order to be able to uti­li­se mate­ri­al flows such as lea­ves, fer­men­ta­ti­on resi­du­es, seed stock or sewa­ge sludge inde­pendent­ly and in a future-pro­of man­ner, Werk­stät­ten hea­ting-sys­tems GmbH has deve­lo­ped holistic ther­mal con­cepts with rota­ry kilns. Under the umbrel­la of the Werk­stät­ten Group, Werk­stät­ten GmbH and Werk­stät­ten hea­ting Sys­tems GmbH par­ti­ci­pa­te in the com­bi­ned expe­ri­ence and exper­ti­se. For our cus­to­mers in the ther­mal recy­cling sec­tor, this means maxi­mum effi­ci­en­cy and reliability.

Rota­ry kilns at a glance:

  • Modu­lar design and con­tai­ner solu­ti­on offer fle­xi­bi­li­ty in terms of location

  • Water-coo­led, rota­ting com­bus­ti­on zone with divi­ded ven­ti­la­ti­on zones for sup­ply­ing fuels with com­bus­ti­on air
  • Ener­ge­tic use of a wide varie­ty of biomasses
  • Slag-free com­bus­ti­on of the most dif­fi­cult fuels
  • Very low CO con­tent in the flue gas pre­vents caking in the heat exchanger
  • Almost stoi­chio­metric com­bus­ti­on in inno­va­ti­ve rota­ry kiln

  • Rated heat out­put: 500 — 5.000 kW
  • Par­ti­al load: 150 — 1.500 kW
  • Appro­val accord­ing to 4th + 17th Blm­SchV possible

The user-friend­ly, self-clea­ning and ful­ly auto­ma­tic com­bus­ti­on tech­no­lo­gy has an inno­va­ti­ve, water-coo­led rota­ry tube tech­no­lo­gy with a num­ber of advantages:

  • Sui­ta­ble for fuels with low ash mel­ting point and high ash content
  • Com­bus­ti­on extends over the ent­i­re length of the rota­ting tube with a tur­bu­lent fla­me vortex
  • All boi­ler com­pon­ents expo­sed to wear and/or high heat loads are lined with refrac­to­ry and wear-resistant concrete
  • In an insu­la­ted post-com­bus­ti­on cham­ber, the flue gases are com­ple­te­ly burnt out befo­re they enter the heat exchanger
  • Emis­si­on values accord­ing to the 4th and 17th BIm­SchV, depen­ding on the fuel, are signi­fi­cant­ly undercut.
  • The pow­de­ry ash is low in car­bon and free of slag; the nut­ri­ent salts it con­tains are avail­ab­le to plants and can be used as fer­ti­li­ser Pos­si­ble forms of ener­gy are
  • hot water, steam and/or ther­mal oil

Examp­les of decen­tra­li­sed ener­gy concepts

  • Digesta­te dry­ing and inci­nera­ti­on for nut­ri­ent con­cen­tra­ti­on and mass reduction
  • Chi­cken manu­re uti­li­sa­ti­on for heat genera­ti­on for sta­bles and properties
  • Steam genera­ti­on or ther­mal oil for indus­tri­al and dry­ing plants by using indus­tri­al by-products
  • Sewa­ge sludge dry­ing and incineration

This com­bus­ti­on tech­no­lo­gy can use the fol­lowing bio­fu­els, for examp­le, for ener­gy with a high degree of effi­ci­en­cy and low emissions:

  • Land­s­cape main­ten­an­ce mate­ri­al, scree­ning of wood­chips, roadsi­de greenery
  • Straw, cof­fee sub­sti­tu­te, seed clip­pings, nut shells, cher­ry pits, coffee/cocoa residues
  • Digesta­te from bio­gas plants, lea­ves, hor­se manu­re, chi­cken manure
