Technology introduction of boiling furnace

With the development and progress of gypsum industry, the need of gypsum powder is growing, also with the quality of gypsum powder. During the whole

procedure, the drying and dehydration are the key link, and it is also the difficult part. According to such a condition, after many years researching and exploring,

we have developed a new generation dehydration device which are suitable for all kinds of gypsum production demand boiling furnace

Principle of working

The main principle of drying system: the boiling furnace body is consist of delicate and intensive cooling coil pipe. Put the heat conductive oil in the pipe, and

release the heat into the inside of furnace. There is a Roots blower under the bottom of boiling furnace, and blow the air into the furnace, until blowing the powder

into boiling status. Under a certain temperature, the dried and dehydrated powder become light, and flow to the outlet automatically. The quality of this kind of

gypsum powder is stable, because the equipment adopts dried electrostatic dust remover, so the dust-removing efficiency is above 95%.

Structure simple and durable

Because we realize fluidization, the furnace does not need moving component, and the structure of the furnace becomes simple. Not only it is easy to manufacture,

but also we do not need maintenance after put into operation. Because we use low-temperature source, so the furnace does not have any risk of being burnt in any

condition, also the equipment will have a long life.

Compact equipment, low area coverage

The boiling equipment is vertical-arranged equipment, and the dust remover on the top of the furnace, make a complete body with the furnace. So the equipment is

compact and low area coverage.

Low energy consumption

The boiling furnace with low heat and electricity consumption. In the part of energy: Most of the heat is used to dehydration and decomposition, and the rest of

small part is used to heat the air from the bottom of the furnace.

The heat efficiency of the furnace is above 95%. Of course the boiling furnace uses the second heat source, and final heat efficiency is amounting to the furnace

efficiency multiply the boiler efficiency. But the steam boiler and the hot oil boiler are all mature hot equipment with high heat efficiency. The steam boiler can

reach to 60%-70%, hot oil boiler can reach to 70%-80%. (our company adopts heat conductive oil furnace), so the general heat efficiency is high. Use steam, it can

reach to 57%-67% .Use hot oil, it can reach 67%-77%.

In the parts of electricity: the boiling furnace does not need move, also without mixer, it realize the fluidization by the steam of gypsum dehydration, because blow

limit air into the bottom of the furnace, so the power of the blower is low, and the boiling furnace have less electricity consumption than the traditional calciner.

Good quality and stable performance

Because adopt low-temperature heat source, so the gypsum is not easy to be burnt, as long as the temperature is controlled properly, there will not have CaSO4

2H2O in the finished product, and the anhydrous gypsum is within 5%, and the rest are CaSO4 1/2H2O.

In order to reach the above requirement, our company have researched and developed a whole set of boiling furnace processing technology, the main material is

good-quality steel. For example, heat conductive oil pipe adopts seamless steel pipe (GB3087-82). Steel plate adopts carbon steel and low-alloy steel (GB713-86);

Frame steel adopts international product .Furthermore, in the work of welding, all the workers have work certificate, after welding, the coil pipe will have a water

pressure test, just in case of leakage of heat conductive oil. The product is qualified if there is no leakage under the water pressure of 1.0~1.5Mpa for 24 hours
