The e-Grate design ensures absolute low emissions with a high degree of efficiency even with variable fuel characteristics. The geometric design of the combustion chamber allows for adequate retention time to allow for clean and efficient combustion of the fuel. Thanks to the in-built Lambda Sensor which continuously monitors the gas values and reacts to changes to Secondary Air supply ensuring complete combustion even at partial load operation. The results are high efficiency, low fuel consumption and extremely low emission values. We offer two seasonal settings in our controller for both Winter and Summer operation. Adjusting the boiler settings during the summer period will reduce the strain on the boiler and will minimise energy consumption and add years to the lifetime of the boiler.
REFRACTORY PERFORMANCE The combustion zone is refractory lined throughout to meet the high-temperature environment. The excellent thermos-mechanical properties and contraction factors are negligible thus resulting in high resistance to thermal shock. This results in a decrease in wall and roof heat losses within the combustion chamber leading to improved energy efficiency.
REFRACTORY LINED BOILER FLOOR Heat retention within the boiler is crucial to provide stable temperatures and aid combustion. Our boiler doors are fully lined with refractory cement to provide optimum heat storage even at part load operation, this minimises ignition starts and reduces emissions.
INTERMEDIATE HOPPER
With our intermediate hopper which is fitted between the boiler and fuel store. The hopper is fitted with a motorised guillotine valve which acts as an airlock between the boiler and fuel store. The hopper is fitted with an Ultrasonic Level Sensor which continuously measures the fuel level in the hopper and rells the hopper when its low-level threshold has been reached.
STABLE COMBUSTION Fuel is transported to the combustion chamber via a Variable Speed (VSD) controlled robust spiral stoker auger. This allows a measured stable supply of fuel to the burner achieving stable combustion.
