Reciprocating Grate Introduction
When we choose Reciprocating Grate, we need know biomass waste characteristics
1. Lower heating value of biomass fuel is different due to different moisture content, while higher heating value is similar. The fuel accumulated outdoors has a moisture content ranging from 12% to 45%.
2. Biomass fuel has high volatile content. Biomass fuel starts pyrolysis when temperature exceeds 170°C, 70%-80% of volatile matter is precipitated, including H2O, CO and CH4.
3. Biomass fuel has no fixed ash melting point. Al, Fe, Ca, Mg and other oxides in the ash increases the ash melting point. However, high K and Na content makes the ash melting point lower than that of coal.
4. Biomass fuel ash has a low density and is easier to be carried by the flue gas. In addition, slagging is easy to form on the convective tube bundle, which affects the heat transfer effect.
5. The overall dimensions of biomass fuel are irregular.
6. The grate is air cooled and divided into three to five zones per lane with one to three lanes in total. The grate bars’ speed and the primary air supply are regulated for each grate zone individually. The individualized control of each zone offers an optimized combustion. The grate bars are made of high-alloyed cast steel and supplied pre-mounted. The grate is function tested before delivery.
