■ Brief Introduction

◎ In this process, potassium chloride and sulfuric acid used as raw materials, and they have a reaction with the high temperature of 500℃-550℃. The product is agricultural potassium sulfate achieved the good quality standard of GB20406—2006 and the byproduct is industrial hydrochloric acid. According the inspection by bureau of quality and technical supervision, all of the K2O content, chlorion content, water content and physical characters have achieved and exceed the level of similar products abroad. The manufacturer can get the hydrochloric acid as byproduct has the concentration at or below 31% according their demand, and the quality achieves the standard of BG320-2006.

■ Characteristics

◎ This technology is a new type of reactor furnace which can improve the Mannheim furnace structure, combined with other specialized equipment, it has successfully solved the corrosion resistant material problem under the environment of high temperature and strong acid and also solved the process technology problem of continuous feeding production. Compared with the similar equipment in foreign countries, its outstanding characteristic is less investment, short build period, high degree of automation, stable operation, high thermal efficiency, strong operability, high product yield, reliable quality and good environmental protection effect.

■ Specification

◎ Materials of Mannheim furnace flue can be divided into two kinds of silicon carbide and alloy steel
