B、Air cooling dry slag drainage system
System principle
MBA-AC dry slag treatment system is a new concept of furnace bottom slag. It uses a special steel strip to collect and transport furnace bottom slag, while using a small amount of natural wind introduced to effectively cool the hot furnace bottom, without cooling it with any water, reducing water pollution and energy consumption. The hot air produced by the slag is directly into the boiler furnace, and the heat taken away from the furnace is brought back to the furnace, thereby reducing the heat loss of the boiler and improving the efficiency of the boiler. When the dry slag is cooled to about 150 degrees, the slag hopper is moved into the slag hopper through the slag crusher, and the slag in the slag hopper can be comprehensively utilized by mechanical or pneumatic conveying.
System characteristics
1、There is no need for water cooling and hydraulic conveyance for conveying ash, so there is no need to set up grout pool and mortar pump and other equipment, without ash water pollution. It avoids the pollution of production site and social environment caused by the maintenance of the original hydraulic slag removal equipment and the leakage and maintenance of the slag pipeline, and achieves the zero discharge standard and saves the water resources. Meet the requirements of environmental protection.
2、The MBA-AC system uses natural wind to absorb the heat of ash, chemical energy and radiant energy of the heated conveyer belt, and send these energy into the combustion chamber, thus improving the efficiency of the boiler. At the same time, the cooling air also provides oxygen to the unburned carbon particles in the ash from the conveyor belt, so that the carbon content of the bottom ash is significantly reduced.
3、The main equipment of the system is made of wire mesh stainless steel belt, and is arranged in completely enclosed box. The slag will not leak out in the process of transportation. The bearing is located outside the shell to facilitate maintenance and replacement. Therefore, there is no effect on the safety of field production. The system can eliminate equipment damage and personal injury caused by furnace slag falling.

2、The mixing ratio is low.
3、Uniform feed can be realized.
Applicable material range
Non sticky, low hardness powder materials (typical materials: biomass power plant ash, limestone powder)
Suitable distance for transportation
Medium distance powder delivery.
（3）Negative pressure pneumatic conveying system
System characteristics
The negative pressure conveying system uses gas pressure below 1kg/cm2. It adopts negative pressure (suction) mode and pulls the powder material at high speed to transport it to the ash warehouse through the pipeline. But it has the obvious advantage of the clean on the site.
（4）Pulse pneumatic conveying system
Application scope:limestone powder transportation
System principle:The compressed gas passes through a certain frequency of the solenoid valve to form a pulse airflow (air knife). The material is cut into a material plug by means of the pressure of the air knife and the pressure of the sending tank, so that the low pressure delivery condition between the material plug and the gas bolt is formed in the pipeline. Depending on the static pressure difference before and after the material bolt, the material is pushed forward to realize transportation.
