- The step grate elements are cleaned by moving the moving grate. These are special, high-quality cast segments. This ensures optimum air supply through the clean combustion grate.<\/li>\n
- The combustion chamber is cleaned by automatic tipping of the combustion ash via tipping grate. The discharge screw underneath transports the ash directly into the ash box.<\/li>\n<\/ul>\n

Automatic cleaning of the heat exchanger<\/h4><\/a><\/li><\/ul><\/div>\n\n- The heat exchanger surface gets cleaned automatically via the integrated turbulators (by lifting and lowering), even during heating operation and therefore kept clean without manual effort. Consistently high efficiency due to cleaned heat exchanger surfaces ensures low fuel consumption.<\/li>\n
- The fly ash is transported to the front ash hopper via screw.<\/li>\n<\/ul>\n

- The removable ash box with wheels enables simple and comfortable emptying of the ash.<\/li>\n<\/ul>\n

Energy saving combustion due to the lambda probe control<\/h4><\/a><\/li><\/ul><\/div>\n\n- The built-in lambda sensor, which permanently monitors the residual oxygen and reacts to different fuel qualities, ensures that perfect combustion values and the lowest emission levels are always achieved.<\/li>\n
- The lambda probe regulates the air and material supply and thus always achieves the cleanest combustion, even in part-load operation.<\/li>\n
- The results are low fuel consumption and the lowest emission values even with different fuel qualities.<\/li>\n<\/ul>\n
