I think those who cook gutter oil can just put it on the fire with a gasoline bucket.
It is possible to convert an ammonia storage tank into a waste oil boiler. The water in the waste oil can be evaporated by installing a coil outside the tank and using heat to boil the waste oil. Such modifications can effectively dispose of waste oil, but safety and environmental protection factors need to be taken into consideration when making modifications. .
Does the design condition of the original ammonia storage tank meet the operating conditions of the waste oil boiler? More caution should be exercised when designing a pressure vessel.; Analyze and identify, review and approve changes, and demonstrate scientifically to avoid problems that may arise if you change things.
The transformation span is a bit big, and my thinking is very active:lol:lol:lol:lol
There is a high probability that it is not feasible, and there are problems such as high energy consumption and failure to reach the boiling point. Without discussing safety, it is enough from the perspective of heat exchange. It is a container with coiled tubes on the outside. The heat exchange area is too small and the heat transfer efficiency is low. For boiling to occur, the heat source inside the coil needs to be at a very high temperature. I have encountered several similar heat transfer cases. The gas generator shell has a water jacket and the temperature inside the furnace is 500-1100°C. It can only produce a small amount of low-pressure saturated steam. A. There is a water jacket outside the aging tank. The circulating water temperature is about 30°C and the material is 60-80°C. It is difficult to drop to 50°C in summer. There is a coil inside the aging tank B. The circulating water temperature is about 30°C and the material is 60-80°C. It is difficult to drop to 50°C in summer. To concentrate waste oil, mature evaporation concentration processes can be considered, such as negative pressure low-temperature concentration using steam as a heat source.
Not very good, not bad either. 1. Without stirring, the heat exchange efficiency is very low and the mass transfer is also slow.; 2. Boiling water in oil will cause it to boil easily. ;
In principle, it is possible, but the large tank is not stirred and the heat transfer is uneven, which affects efficiency and steam utilization.
Now it has been changed to remove the original coil, reshape it and put it inside the tank to improve the heat transfer efficiency.
