Underfeed combustion 390 to 1,250 kW<\/h1>\n

The mov\u00ading infeed grate, proven com\u00adbus\u00adtion retort and slop\u00ading exter\u00adnal grate in the PYRTEC opti\u00admal\u00adly com\u00adbine the ben\u00ade\u00adfits of infeed and under\u00adfeed com\u00adbus\u00adtion. A feed screw con\u00advey\u00ador guides the wood fuel into the com\u00adbus\u00adtion retort, where it is pre-dried. The fuel is com\u00adplete\u00adly degassed on the exter\u00adnal grate and the mov\u00ading infeed grate. The wood gas\u00ades are then burned with the aid of a reg\u00adu\u00adlat\u00aded sup\u00adply of sec\u00adondary air.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

The com\u00adbus\u00adtion tech\u00adnol\u00ado\u00adgy of the PYRTEC achieves low emis\u00adsion val\u00adues (par\u00adtic\u00adu\u00adlar\u00adly for CO and NOx<\/sub>). Oper\u00ada\u00adtion with mod\u00adu\u00adlat\u00ading out\u00adput con\u00adtrol and the opti\u00admised com\u00adbus\u00adtion prin\u00adci\u00adple enables effi\u00adcien\u00adcy lev\u00adels of up to 92 per\u00adcent.<\/p>\n

Top qual\u00adi\u00adty design and con\u00adstruc\u00adtion<\/strong><\/p>\n

The PYRTEC wood boil\u00ader fea\u00adtures high qual\u00adi\u00adty con\u00adstruc\u00adtion for use under the tough\u00adest con\u00addi\u00adtions (high fuel flex\u00adi\u00adbil\u00adi\u00adty from M10 to M50). The inside of the com\u00adbus\u00adtion cham\u00adber is lined with pressed fire\u00adclay bricks with a high clay con\u00adtent for greater dura\u00adbil\u00adi\u00adty. All grate ele\u00adments are high qual\u00adi\u00adty, heavy gauge chromi\u00adum steel cast\u00adings that can with\u00adstand very high tem\u00adper\u00ada\u00adtures. A dis\u00adtin\u00adguish\u00ading fea\u00adture of the PYRTEC wood boil\u00ader is its proven three-pass heat exchang\u00ader, pro\u00advid\u00ading max\u00adi\u00admum heat trans\u00adfer and excep\u00adtion\u00adal effi\u00adcien\u00adcy.<\/p>\n<\/div><\/div><\/div>
