Shutdown four tons of gas boiler china factory price coal steam boiler price shutdown and maintenance of fire into pressure shutdown, normal shutdown, emergency shutdown. A pressure fire fire shutdown shutdown pressure applied to temporarily stop the supply of steam, the boiler is shutdown pressure hot standby state. 1, before the pressure reduction appropriately to fire the boiler load, and according to the length of the seam thicker shutdown time, (up to 200mm) to accelerate the speed of the grate, the grate is stopped when rotated about 1.5 meters from the coal seam to the shutter. 2, stop blowers, blower suitably adjusted flap subsections, relying on a lean-burn natural ventilation is maintained. 3, the sewage, to allow the water level in the boiler water level. 4, Yang fire regularly, to prevent rotation of the furnace grate extinguish the fire bed. Young fire first before sewage water, then rinse water level gauge. II. Normal shutdown Normal shutdown for heating period ends, boiler pour fire into the buck repair or maintenance. 1, make a record before shutdown problems in operation, so that after the shutdown process. 2, the coal bucket coal memory runs out, the amount of toner to reduce the wind. 3. Stop the blower, draft fan stop and then the opened door grate ash. 4, after the steam supply is stopped out, the boiler to the boiler water to maintain a high level. 5, close the main steam valve, if the pressure rises to open the air exhaust valve suitable pressure relief. 6, stop the water supply to the boiler and economizer attention to monitoring changes in water temperature, open return pipe if necessary. 7, 4 to 6 hours after the furnace fire bed down exhausted, continued rotation of the cooling grate. Throughout the boiler throttle, the door should be kept closed. Allowed to naturally cool. 8, appropriate to open the pump, the boiler water and sewage. When the pressure drops to zero, open the air valve. 9, when the boiler water temperature is below 70 ℃, boiler water can be exhausted. Shutdown is complete. 10, less than 24 hours during shutdown. Avoid Shutdown cooling process, step-down too fast. Third, emergency shutdown emergency shutdown applies to the boiler accident, g combustion equipment damage, furnace or boiler structure collapsed wall is red-hot, a serious threat to the safe operation of the boiler when; h boiler pressure parts found serious distortion, leakage. when i found flue gas explosion or secondary combustion, boiler and seriously endanger the safety of operating personnel;; when endanger the safety of operation.. the safe operation of the boiler j endanger other unusual circumstances when. 2, the emergency shutdown procedures to immediately stop a blowing coal and reduce the wind; B rotates quickly grate, the pour slag pit coal or sand, wet ash coal burning fire to extinguish. , but not to the firebox water;. c boiler air valve, the relief valve opens quickly exhaust the steam pressure is reduced;. d after the fire goes out, stopping fan, opening the ash door and door, promote air circulation accelerated cooling; 3, emergency shutdown Notes a. when an accident and emergency shutdown due to lack of water, boiler feed water is strictly prohibited to, and shall not be such as to open the air valve or exhaust valve work on preventing boiler from sudden changes in temperature or pressure to expand accidents;. b when filled with water due to an accident and emergency shutdown, should immediately stop the water supply, reduce combustion, open the drain valve and drain, due to lower the water level, while opening the main steam pipe, the sub-cylinder and steam traps mother tube, water and prevent steam pipe with a large number of water hammer occurs. c. emergency shutdown operation to ensure the safety of the main event of an accident to calmly deal with, timely reporting, and make relevant records in the "log table boiler." d. Whether shutdown any case, we must maintain timely contact with steam departments.

Boiler startup startup boiler combustion adjustment method should pay attention to the flame monitoring, combustion and make adjustments as follows: (1) correct the ignition. Adequate ventilation furnace before ignition, the ignition first investment ignition device (or torch), then turn the gun. (2) diagonally administered fire mouth, pay attention to timely switch, the flash point was observed nozzle suitable fire, flame sought uniformly distributed in the furnace. (3) to adjust the lead note, air volume, furnace pressure should not be too large. (4) in particular to monitor exhaust gas temperature when combustion instability, the occurrence of the back pass to prevent the secondary combustion. (5) to maximize the temperature of primary air, secondary air is fed reasonable depending on the fuel. Adjusting the temperature difference between both sides of the cigarette. Do pulverizing system-OFF stable (6) operation. Stoker coal under stable powder machine speed and stability. Coal with wind stability and oxygen stable. Steam temperature, steam pressure increase stability and load stability liter.
