1. Oven time and temperature control points are different due to different refractory materials and metal heating surface materials. It should be carried out in strict accordance with the heating curve of the oven. The temperature should be raised slowly, and the flame distribution should be uniform.For example, the oven temperature of high-strength wear-resistant castables in a circulating fluidized bed boiler can be referred to as follows: temperature range (℃) rise (decrease) temperature speed (℃/h) required time (h) normal temperature ~ 1505 ~ 1013 ~ 26150± 5024150～31510～1511～16.5315±5036315～54020～257.5～9540±5024540－Normal temperature<25/2. During the oven, the boiler water level should be kept normal, and the expansion of the boiler drum and each header should be monitored and recorded.

1. Turn on the induced draft fan to discharge the gas from the furnace; spread the prepared firewood and base material, with a thickness of about 250 mm, and then ignite it with a torch. At the beginning, the ventilation volume should be small, and the fire should be carried out according to the requirements of the heating curve. Turn on the induced draft fan to make the flue gas flow slowly, increase the rotational speed of the induced draft fan in the middle and late stages, and heat up according to the oven curve.2. Oven standard: based on the moisture content of the brick wall.When the refractory brick mortar moisture content of the furnace wall reaches about 7%, and the red brick mortar reaches 7-10%, it is possible to start the furnace without baking the furnace separately. After the furnace is finished, the moisture content of the furnace wall mortar is below 2.5%. Oven finished.

1. The boiler body is installed, the furnace wall and insulation work are completed, and the natural maintenance is 5-7 days; 2. The trial operation of each boiler system is completed; 3. The thermal instruments and measuring points required for the oven have been installed and calibrated; 4. Prepare enough fuel for the oven (such as firewood, bottom material, carbon block); 5. Contact the steam turbine personnel to fill the boiler with water to ensure that the water level is at the normal water level.6. After inspection by the testing department, the hydraulic test is qualified.

In order to ensure the reliability of each part of the furnace wall of the boiler and long-term use at different temperatures, gradually evaporate the water, and ensure the strength and airtightness of the furnace wall, the newly installed boiler and the newly built furnace wall are naturally cured. , the oven must be carried out.The oven process is actually two stages, namely the natural drying stage during construction and the heating and baking stage.
