Embodiment 1
[0019] A kind of anticorrosion agent for biomass boiler, which is composed of coal ash, Al 2 (SO4) 3 , kaolin and CaSO 4 Composition, the mass of each component in the anti-corrosion agent is: 4kg coal ash (particle size 0.05-0.015mm), 2kg Al 2 (SO4) 3 , 3kg kaolin, 1kg CaSO 4 .
[0020] Above-mentioned biomass boiler corrosion inhibitor, its preparation method is as follows:
[0021] Step (1): Calcining 4kg of coal ash with a particle size of 0.05-0.15mm in a muffle furnace at 1000°C for 1 hour;
[0022] Step (2): Add 2kgAl 2 (SO4) 3 , 3kg kaolin, and 1kg CaSO 4 Grind to 0.05-0.1mm respectively, and add calcined coal ash for stirring, and after stirring evenly, press to form particles with rough threads on the outer surface.
[0023] Step (3): Bake the anticorrosion agent particles in a muffle furnace at 200°C for 0.5h to prepare the anticorrosion agent for biomass boilers. (of which coal ash, Al 2 (SO4) 3 , kaolin and CaSO 4 The mass percentage content is respec...
Embodiment 2
[0027] A kind of biomass boiler anticorrosion agent, this anticorrosion agent is made of coal ash, Al 2 (SO4) 3 , kaolin and CaSO 4 Composition, the mass of each component in the anti-corrosion agent is: 3kg coal ash (particle size 0.05-0.015mm), 1.5kgAl 2 (SO4) 3 , 4kg kaolin, 1.5kg CaSO 4 .
[0028] Above-mentioned biomass boiler corrosion inhibitor, its preparation method is as follows:
[0029] Step (1): Calcining 3kg of coal ash with a particle size of 0.05-0.15mm in a muffle furnace at 1050°C for 1.5h;
[0030] Step (2): Add 1.5kgAl 2 (SO4) 3 , 4kg kaolin, and 1.5kg CaSO 4 Grind to 0.05-0.1mm respectively, and add calcined coal ash for stirring, and after stirring evenly, press to form particles with rough threads on the outer surface.
[0031] Step (3): Bake the anticorrosion agent particles in a muffle furnace at 150° C. for 1 hour to prepare the anticorrosion agent for biomass boilers. (of which coal ash, Al 2 (SO4) 3 , kaolin and CaSO 4 The mass percenta...
