Gasification furnaces are widely used in nitrogen fertilizers, soda ash, city gas and other industries. The advantages and disadvantages of gasifiers directly affect the stability, high production, safety and energy consumption of the entire production plant. The hearth is the main component of the gasifier and is called the “heart†of the gasification. The use of high wind speeds for gas production requires the selection of furnaces with reasonable air distribution, uniform gasification agent distribution, strong slag discharge capability, high gasification intensity, large gas production capacity, long service life, and high technological content. Quzhou Dongfang Chemical Machinery Co., Ltd. has changed the burning of small coal, small seed coal, briquette coal, local coal, and inferior coal in domestic synthetic ammonia plants, and the gasification furnace model has continuously expanded from 2400 to 2610, 2650, 2800, 2880, and 3000. Situation, developed a multi-layer, multilateral series dedicated furnace. This furnace has a novel structure, adaptability to various furnace types and coal types, large ventilation area, more reasonable layout, and high gasification intensity.
It is understood that before this, Zhangzhou Dongfang Chemical Machinery Co., Ltd. has won the bid for the conversion of 8 sets of 2610 gas furnaces in Shandong Feida Chemical Technology Co., Ltd. The gas output from the single furnace is increased to 7000m3/h, and the ammonia consumption per ton is reduced to 1200kg; Shandong Ruixing Chemical Co., Ltd. The 20 gas furnaces of the company have all adopted the DF multi-layer and multi-purpose furnace, and the ammonia consumption per ton has dropped from 1,450 kg to less than 1200 kg. According to statistics, currently, Zhangzhou Dongfang Chemical Machinery Company has an annual output of more than 2,000 special furnaces, over 1,000 sets of anti-displacement ashtrays with central positioning, and more than 100 sets of furnace bottom assemblies.
Jib cranes developed by EUROCRANE have multiple specifications and types.We are able to provide you with the best solutions no matter you have any special requirements for lifting weight,rotating angle,jib length and functions.Its range for load is from 80kg to 10000kg.It is widely used for material transportation in operating posts,especially in smaller operating area,to greatly shorten the handling time and improve the working efficiency.
Jib crane of EUROCRANE have rotating angle of 180°,270° and 360° depending on operating area and range.It can be devided into wall jib crane and column jib crane according to the installation modes and structures.Also it can be devided into manual and electric jib cranes based on the rotating modes.Jib crane also has other types,such as foldable jib crane,movable jib crane and wall travelling crane.You can choose the type according to your requirements.
