5.1.2 For small auxiliary steel furnaces with design pressure less than 0.78MPa and steam output not more than 1t/h, only positive balance heat test can be carried out. 5.1.3 The thermal test items of exhaust gas weak furnace and exhaust gas combined boiler can be carried out according to the content agreed upon in the order negotiation between the two parties.
5.2 Safety test
5.2.1 The steam safety test should be conducted by raising the steam pressure in the steel furnace to the designed start-up value, and the start-up value of the safety valve should be observed and recorded.
5.2.2 The steam safety valve test should be conducted with the steam valve closed, 100% of the negative pressure in the furnace fully burned, and the water level kept within the safety water level range, and the start-up value should be observed and recorded. For combined boilers that can use both oil and gas, the steam test should be conducted during navigation.
5.2. 3. Manual opening test of steam safety valve, the opening handle of steam safety valve should be pulled quickly to conduct the test. 5.3. Oil injection test
The oil injection test of silver furnace combustion solution should be conducted in accordance with the relevant provisions of GB1C837. 5.4. Cold furnace heating test
The cold furnace heating test of boiler should record the time from cold furnace ignition to steam pressure reaching the working pressure. During the test, the steam valve and sewage valve must be closed, and the fire must not be stopped. 5.5. Automatic and manual control test
The boiler Automatic and manual control tests shall be conducted in accordance with the relevant provisions of CB, 3161. 5.6 Determination of steam humidity and exhaust temperature
