5 Startup
5.1 Boiler Water Filling
5.1.1 Boiler
JB/T 10354--2002
Open all air valves and pressure gauge connecting valves, close the drain valve, main body pipe and valves in the pipeline, and open the boiler water! Water: When filling water, the air valve and superheater air valve of the boiler should be opened. The water filling speed should be determined according to the requirements of the boiler manual. During the water filling process, check whether the air is exhausted, whether there is any leakage in the boiler, the door of the header, and the foot valves, flanges, and headers of each part. When the water is taken to the lower safety water level, stop the water for inspection. If there is a problem, handle it: otherwise, fill the water to the normal water level. 5.1.2 Hot water boiler and pipe network system
Before filling the hot water boiler with water, all drainage and water filling pipes should be closed, all air valves should be opened, and the bypass valves connecting the water supply and return water at the end of the pipe network should be opened. Fill water until the air at the top of the steel furnace, in the pipe network, and in the gas collecting tank is discharged, and the air is turned off. After the system is filled with clean water, the pressure gauge in the steel furnace room should not be lower than the static pressure of the most commercial user in the pipe network. The maximum value of the stop error is: 5.2 Ignition
The boiler that has been out of service for more than three months should be started. The operation manual of the steel furnace manufacturer should be selected. 5.3 Ignition
5.3.1 First open the explosion barrier of the grate boiler
to carry out natural ventilation, prepare the ignition and sufficient ignition materials, and start ignition. When igniting, fuel that may explode should not be used. Before ignition, the hot water boiler should start the circulating water system. When the water reaches a certain temperature (depending on the conditions and site regulations), start the fan for ventilation with a small air volume and add new coal. When steam is released from the air, the air valve can be closed to increase ventilation and firepower, and the fire can be raised in reverse. 5.3.2 Other boilers
Other ignition methods for other boilers shall be in accordance with the instructions provided by the boiler manufacturer. 5.4 Pressure increase and steam generation of steam turbine boilers
5.4.1 Pressure increase
5.4.1.1 In order to ensure that the boiler does not produce excessive temperature stress, there should be a certain amount of time from the cold state of the boiler to the ignition to the working pressure, and the time should be reversed according to the instructions provided by the boiler manufacturer. 5.4.1.2 When the air discharge from the air room is completely steam, close the air valve, the air valve and the drain valve of the inlet header and the intermediate box of the superheater should also be closed: but the air valve of the outlet header and the drain valve of the outlet header should remain open until the steam is discharged. 5.4.1.3 When the pressure rises to about 0.05Mia~0.1MPa, flush the water level gauge: 5.4.1.4 When the pressure rises to 0.1MPa-0.15MPa, flush the pressure gauge pipe. 5.4.1.5 When the pressure rises to about 0.3MPa, check whether there is leakage at each replacement, and re-tighten the flange screws of the manhole, hand hole, and emergency repair. At this time, the steam pressure should be kept constant. After the steam pressure rises: do not re-tighten the medium. 5.4.1.6 Perform a cleanup and pay attention to maintaining the water level. 5.4.1.7 When the pressure rises to 0.4MPa-0.6MPa, open the main steam for normal operation. When warming up the pipes, check to avoid water leakage. The warming up time is determined by the distance of steam rise. When the main steam is fully open at the end of the warming up, flush the water gauge and pressure gauge again. 5.4.1.8 When the pressure rises to the upper visible pressure, flush the water gauge and pressure gauge again. 5.4.1.9 During the pressure rise process, pay attention to controlling the combustion, so that it will gradually increase, and pay attention to maintaining stability. 5.4.1.10 Pay attention to maintaining the water level during the pressure rise process. If the water level is too high, use partial water discharge to reduce it. If the water level is too high, add water. 5.4.1.11 For non-piano economizers, the bypass flue gas should be operated in sections to make the economizer outlet water temperature at least 30℃ lower than the emergency temperature. The recirculation pipe without bypass flue should be vented to maintain the water temperature at the economizer H port. 5.4.1.12 After the valve of the steam pipeline is opened, in order to prevent it from getting stuck due to thermal expansion, it should be fully opened and then half-opened. 5.4.2 Setting of safety valves
B/T103542002
When the pressure of a renovated or newly used boiler is increased for the first time, the safety valves should be set. The setting should be carried out in accordance with the provisions of the Safety Technical Supervision Regulations for Steam Boilers and the Safety Technical Supervision Regulations for Hot Water Boilers. 5.4.3 Steam connection
5.4.3.1 When connecting steam, the boiler pressure should be slightly lower than the steam mother pipe pressure to prevent the pressure drop during steam connection from causing the water in the boiler to evaporate rapidly. 5.4.3.2 Before recirculating steam, the boiler water level should be at the lowest safe water level to prevent the steam from carrying water during steam connection. 5.4.9.3 Before steam connection, analyze the steam supply, and the steam quality should be qualified: 5.4.3.4 When steam is connected, open the bypass valve of the steam connection valve first, and then open the steam valve. Open the valve slowly, and close the bypass valve of the steam connection valve, the drain valve before connection, and the superheater drain valve after the steam connection valve is opened. 5.4.3.5 During the steam connection, pay close attention to the changes in air pressure, air temperature and water level. 5.4.4 Operation after steam connection
5.4.4.1 After steam connection, open the flue damper of the economizer and close the bypass flue damper of the economizer. For boilers without bypass flue, close the valve of the economizer recirculation pipe to make the economizer run normally. 5.4.4.2 Open the continuous blowdown. When the furnace reaches 70% of the rated load and the water level is normal, the direct-acting adjustment device for the supply and combustion is put into operation
5.5 Hot water boiler heating
