Sugar Refinery Coal Fired Boiler|DZL Packaged Chain Grate Boiler

Introduction of Sugar Manufacturing Process  

The bagasse produced after extracting the juice from sugar cane is used as fuel to generate steam in factories. Increasingly large amounts of bagasse are being made into paper, insulating board, and hardboard and so on.

Nowadays, harvesting of both cane and sugar beet is done primarily by machine, although in some states it is also done by hand. The harvested cane stalks and beets are loaded mechanically into trucks or railroad cars and taken to mills for processing into raw sugar. Once there, they are cleaned, washed, milled to extract juice, filtered, and purified. The result is a clear, sugar-filled juice.

After being purified, the clear juice undergoes vacuum evaporation to remove most of the water. In this process, four vacuum-boiling cells are arranged in series so that each succeeding cell has a higher vacuum. The vapors from one body can thus boil the juice in the next one, a method called multiple-effect evaporation. Next, the syrupy solution is vacuum-crystallized to form sugar crystals. The remaining liquid is removed using centrifugaling and drying, and the sugar is packaged.

Introduction of DZL Packaged Chain Grate Boiler

Coal fired boiler are widely used in sugar manufacturing process, because its high stability and widely adaptability. DZL packaged chain grate boiler use coal as its fuel, with high efficiency and good performance. This double-wind-gas-duct series boiler is independently developed by our company as the fourth generation horizontal water tube and fire tube package boiler in the 1980’s, survived from many tests and practices. This boiler has been awarded as the following: National High Quality Product Prize, Provincial High Quality Product Prize, Provincial Prize in Science and Technology, etc.
