Gasification
board or gasification groove is an auxiliary part of intermediate bunker, ash
bucket, flat-based warehouse and cone-based warehouse. It is usually installed
at the bottom of material storage warehouse or one side of ash bucket. By
connecting preheated air during unloading, this equipment can fluidize powdery
material which enhances fluidity of material. This will smoothen the unloading
process and avoid particles arching or bridging.

It is understood that avermectin is a new class of antibiotics with novel structures and dual functions of farming and livestock. With the improvement of people’s living standards and the call for green food, such biological pesticides have become popular in the current pesticide market. Abamectin has also become the most popular and most competitive new product in the current biopesticide market.
Wei Xiaodong, general manager of the Zweihuang production base in Weiyuan, Hebei, told reporters that as a biological pesticide, the price of avermectin has not risen. By 2004, prices per kilogram remained at around 2,300 to 2,500 yuan. Last year, they fell drastically. The lowest price reached 700 yuan, which was close to the production cost of the company. This caused most of abamectin production companies to face cost pressures and unable to turn around.
Speaking of the reasons for this year's avermectin price recovery, a manager surnamed Zhang, who represents a number of avermectin manufacturers, said that this is all dependent on the country's major policies. With the gradual ban on high-toxic pesticides in the country, biological pesticides such as avermectin have entered the field of vision of farmers.
According to statistics, before 2005, high-toxic organophosphorus pesticides accounted for 70% of total pesticides, while methamidophos accounted for 70% of highly toxic organophosphorus pesticides. These two “70%†have long hindered the development of biopesticides. pace. In 2005, the state increased the management of highly toxic pesticides. Of the 4123 pesticide products newly registered and approved, the number of highly toxic and highly toxic products was only 26, accounting for only 0.63%, which was the lowest in the calendar year. With the country’s strict restrictions on the production and use of highly toxic pesticides and the fact that the price of abamectin has reached the level acceptable to farmers, the marketing of avermectin has gradually become smooth.
At present, Hebei Xingbai Pharmaceutical Group, Hebei Weiyuan Biochemical Co., Ltd., Zhejiang Shenghua Biotech Co., Ltd., Shandong Qifa Pharmaceutical Co., Ltd., Zhejiang Qianjiang Biochemical Co., Ltd. and other avermectin companies are Step up production.
Since February, abamectin prices have skyrocketed, increasing from the 750 yuan/kg at the end of last year to the current 1150 yuan/kg. At the same time, the demand for abamectin in the market is also in short supply. It is reported that this is due to the country's strict restrictions on the production and use of highly toxic pesticides.
