Doppler probe is used instead of pyroelectric probe to eliminate the probe dead Angle and improve the reliability of LED lamp. The controller adopts the intelligent device PLC10F200 as the control core, and the multi-aluminum alloy gravity casting Popler core device uses 2SC1907, which is compatible with each other, stable and reliable. Related production techniques need to be improved to improve product reliability. This project material separation does not use any special equipment or separation components, by pay combustion chamber, burnout chamber, large expansion capacity rotary channel, silo and other natural components of the whole membrane water wall inertial gravity separator, to achieve material separation, heat transfer dual functions. The problems such as the coking in the ash and the unsuitable placement of the ash superheater caused by high temperature corrosion in the low melting point furnace ash casting co., LTD., which takes biomass and municipal waste as raw materials, have been solved fundamentally. The technical indicators of the product reach: JB/ T7985-2002; GB13271-2001 standard, and is expected to further reduce the volume of the boiler on this basis, become a household boiler.
