Flue gases are cooled down from 700\u00b0 to 300\u00b0 in a steam generator, the resulting heat being reused for warm water, steam or electricity. The waste water resulting from the exhaust gas cleaning process is collected in the water spray reactor from which it is directly injected into the hot \ufb02ue gas (300\u00b0C). Consequently, water evaporates while the solid particles (salts) are separated in the bag \ufb01lter.[\/vc_column_text][\/vc_column][\/vc_row][vc_row css=&#8221;.vc_custom_1552637157525{margin-top: 20px !important;margin-bottom: 20px !important;}&#8221;][vc_column width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;.vc_custom_1552637234116{margin-bottom: 0px !important;}&#8221;]<strong>Burner<\/strong><br \/>\nThe burner, placed on the front of the rotary kiln, is a multi fuel burner (gas, liquid) disposing of its own draught. An interconnection system adds proportional quantity of air and gas. Every burner disposes of the checking equipment and shut-off arrangements required by law.<\/p>\n<p><strong>Fuel pressure and combustion air pressure<\/strong><br \/>\nBurner draughts are set off by activating the automatic \u201cburner air\u201d system or automatically when the kiln temperature exceeds 300\u00b0C in order to avoid the overheating of the air feeding unit. Burners are operated automatically.<br \/>\nThe temperature in the burning chamber can be regulated according to burner set values indicated by the control system.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_gallery type=&#8221;image_grid&#8221; images=&#8221;12085,12088,12091,12100&#8243; img_size=&#8221;219&#215;138&#8243; onclick=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row fullwidth=&#8221;true&#8221; fullwidth_content=&#8221;false&#8221; css=&#8221;.vc_custom_1552640544174{margin-top: 40px !important;margin-bottom: 40px !important;padding-top: 20px !important;padding-bottom: 20px !important;background-color: #e2e2e2 !important;}&#8221;][vc_column width=&#8221;1\/4&#8243;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_images_carousel images=&#8221;12104,12107&#8243; img_size=&#8221;full&#8221; onclick=&#8221;link_no&#8221; autoplay=&#8221;yes&#8221; wrap=&#8221;yes&#8221;][vc_column_text css=&#8221;.vc_custom_1552637699347{margin-bottom: 0px !important;}&#8221;]\n<p style=\"text-align: center;\"><strong>Rotary kiln with burner<\/strong><\/p>\n[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/4&#8243;][\/vc_column][\/vc_row][vc_row fullwidth=&#8221;true&#8221; fullwidth_content=&#8221;false&#8221; css=&#8221;.vc_custom_1552640815230{margin-top: 40px !important;margin-bottom: 40px !important;}&#8221;][vc_column width=&#8221;1\/4&#8243;][vc_single_image image=&#8221;12114&#8243; img_size=&#8221;full&#8221;][\/vc_column][vc_column width=&#8221;3\/4&#8243;][vc_column_text css=&#8221;.vc_custom_1552638091618{margin-bottom: 0px !important;}&#8221;]<strong>Ash removal from the boiler<\/strong><br \/>\nOur cleaning procedures foresee the installation of low frequency vibrators for the superheater and economizer of the kiln.
