It is a windy today, one of the Indian customers came to our company for a visit for green grass drying plant. The initial moisture of raw material is 75%, and the final moisture is 12%,the final products after drying will be used as animal feed , so the quality of the green grass should be guaranteed, such as the color of the grass, the low temperature during the drying process. According to the customer’s requirement, we designed the special biomass purification heat stove, because there is abundant biomass fuel such as wood chips, rice husk, coconut shell ,straw etc. The structure of the purification stove includes: Combustion furnace, high-temperature dust pre-collector, heat exchanger, coal bucket elevator, grate reducer, slag scraper remover, electric control equipment, blower, circulating fan, hot-air blower, flue gas draught fan, Combustion furnace, high-temperature dust pre-collector, heat exchanger, coal bucket elevator, grate reducer, slag scraper remover, electric control equipment, blower, circulating fan, hot-air blower, flue gas draught fan, deduster, flue and chimney, flue and chimney. Heat exchangers are tubular multi-stage series exchangers .To solve the problems of ash deposition in tubular exchanger, we design a kind of high-temperature deduster. 80% ash in high-temperature flue gas is removed through deduster before it enters heat exchanger. The left ash can be taken out of the exchanger by gas flow and hard to deposit. This technique has been authorized national patents and can extend the cleaning period for years.
After the discussion of the drying techniques and equipment design, the Indian customers went to the workshop for a visit. Our engineers gave detailed description about the related products ,and the customers had a great praise on our equipments and the advanced techniques. And they express they were interested in our products very much and make the initial cooperation with us. Related pictures are as follows:
