Main steam valve should be installed near the outlet of the drum or header of the superheater. Main steam valve vertical shell boilers and heaters in the county of vellore may be installed in the boiler room to facilitate local operations. On each steam boilers and steam pipes connected to main pipe, two gate valves shall be installed, should be fitted with a valve and open to the atmosphere between the trap valve, the inner diameter> 18mm.

Talk about safety rules steam boilers and heaters in the county of vellore steam boiler is a gas often in special equipment working under high temperature conditions, improper operation will have a risk of explosion. To ensure their safety, economic operation, specially formulated the following procedure: First, the duty must strictly observe labor discipline, not AWOL, not doing things unrelated to the unit during operation, and strictly enforce the rules must not illegal operation, and strictly drunk and sick to work. Second, keep an eye on the water level and pressure changes, so that combustion stability, stable water level, steam pressure stable. Is strictly prohibited water, full of water and overpressure run accident occurs. Once the severe water shortage in the boiler found that the boiler water is strictly prohibited! Third, the periodic flushing water pressure gauges, which remains clean and bright, easy to observe. Automatic water level control, over-pressure protection device and alarm device chain, must always be sensitive and reliable in the state, found that the problem should be repaired in time. Fourth, the valve should have regular manual test (once a month, a day shift within a month, the operation should gently pull handle with care) and vapor dynamic test (per quarter) for a day shift) to maintain its sensitive and reliable. V. earnestly implement sewage system and operating requirements, to reduce the level of emissions per 25 ~ 30mm is appropriate, should run at a high pressure, low load. Sixth, the duty should be carried out inspection tours in the boiler, in order to grasp soon safety accessories and a boiler ancillary equipment (such as economizers, pumps, motors, valves, etc.) can not be found safe operation of boiler feed water to the boiler or other threatening when running situation, should immediately stop running. Seven, water quality testing staff often get in contact, water quality control, water quality strict implementation of national industry standards, strengthen water quality management, to avoid the knot raw scale and corrosion inside the drum. Eight, careful operation, outside the fireman on duty personnel at any other person shall tamper with the console press the knob in the boiler and valves, instrumentation, etc., fill out the log boiler.

Various localities will accelerate the cogeneration and district heating coal heating in the region. In the central heating pipe network coverage area, prohibit new construction, renovation, expansion of distributed coal-fired heating boilers; central heating pipe network coverage prior to the completion of use of scattered coal-fired heating boilers have been built and can not meet emissions standards coal-fired heating boilers, demolition will be completed within the deadline.

For violation of the provisions, sales do not meet the quality standards of civilian coal for coal, or the ban on coal sales coal region and its products, the people's government above the county level by the market supervision and management department confiscated of raw materials, products and illegal income, impose a fine of three times the value of the amount more than doubled.
