(1) the use of firewood and coal oven, according to the superheater after the smoke temperature and furnace, cyclone Jane, electric heating corner control combustion intensity, the first day must not exceed 100℃, after every day heating 50℃.

(2) temperature rise to add ambient temperature, oven to frequently add firewood, each quantity should not be too much, specific to see the temperature rise and reduce temperature fluctuations as far as possible.

(3) the oven to maintain the normal water level in the furnace, open to empty exhaust valve, so that the steam emptying, maintain the pressure of 0.2 ~ 0.3MPa in the furnace.

(4) oven temperature as smooth as possible, check the furnace wall to prevent blowout, peeling and concave and convex deformation phenomenon, check the expansion of each part, record the expansion indicator.

The circulating fluidized bed boiler USES wear-resisting, fire-resistant heat preservation and the related material, because the material material, the manufacturer to the material material request and the production craft are not identical, on the material quotation has the difference, also has the difference in the boiler use effect and the life.The time varies from several months to several years, but the composition of combustor has a direct influence on the service life of boiler.For example: gangue inferior coal of various compounds.Our solemn commitment is to operate as well as possible in the worst working conditions for three years without major repair, or even longer.

The specific oven scheme is delivered along with the project progress.The heating curve table of oven is attached.
