1, boiler factory should be accompanied by "technical safety specifications of the design documents, product quality certification, safety and the use and maintenance instructions, supervision and inspection certificate (safety supervision and inspection certificate performance)."

2, boiler installation, maintenance, alteration. Engaged in the installation of the boiler, maintenance, renovation of the unit shall obtain special equipment installation and maintenance certificates issued by the Provincial Quality and Technical Supervision, before engaging in the boiler installation, maintenance, alteration. Construction unit before construction will be prepared for installation, maintenance, alteration in writing inform the special equipment safety supervision and management department of the municipality or district, and will start informing sent to the local county level Quality and Technical Supervision for the record, told immediately after construction.

3, inspection of boiler installation, maintenance, transformation. After construction, the construction unit of Special Equipment To Quality and Technical Supervision, Inspection and declared the boiler installation supervisory inspection and hydrostatic testing. After passing by the Quality and Technical Supervision, Special Equipment Inspection, County of Quality and Technical Supervision involved in overall acceptance.

4, registration boiler. After the boiler inspection, the use of units must be in accordance with the "special equipment registration and use of management rules", fill "boiler (census) Registration Form" to the Quality and Technical Supervision registered, and obtain a "safe use of special equipment registration certificate" .

5, operation of the boiler. Boiler operation must be performed by trained and qualified to obtain "special equipment operator certificate" certified personnel to operate, must strictly abide by the rules and eight systems, six record.

6, check the boiler. Periodic inspection of boiler once a year, not be used without safety periodic inspection of boilers.

Matters needing attention and standard flow of water process before entering the boiler periodic sewage discharge operationOperational notes and standardized procedures for boiler periodic discharge: 1. Periodic Sewerage notices 1. The main value of the furnace should be contacted before the discharge is discharged, and the steam turbine can be approved before it can be carried out. 2. When discharging water level is normal, after discharge, check whether each sewage door is closed tight. 3. Sewerage doors should not be opened to more than 30s, can not open two or more sewage doors at the same time, in order to prevent damage to the water cycle. 4. Open the drain door slowly in case of water shock. In case of water shock, close the valve until the shock disappears, and then slowly open the drain door. 5. When operating the valve, you should stand on the side of the valve, strictly prohibited Right to the valve. II. Discharge operation flow 1. After receiving the scheduling task, labor protection supplies dressed neatly, with a special F wrench, on the spot open the general gate. 2. Open all the doors, contact the DCS screen of the furnace to open the corresponding discharge electric door, after the discharge, first close the second door, then close the door, one by one, one by one. All sewerage is over, close once door of each discharge and main gate of sewerage 3. When discharging water, we should pay close attention to the water level. If there is any abnormal water level or accident, the discharge should be stopped. For 2 hours, the door cores of each discharge door shall be checked for leakage, and if the drain is lost, the drain door shall be opened promptly once. Note by removing residue that may be stuck in the core of the door (boiler principal value should be contacted before operation): the whole drainage process should be in close contact with the DCS operator.

About steam water process before entering the boiler superheater tubes 1 Blasting failure, bursting phenomenon superheater tubes a. Steam discharge sound or explosions near the superheater. B. abnormally decreased steam flow, and the flow is not less than the water flow normally. C. furnace pressure is reduced or made positive, the door severe, see the fire and smoke outwardly steam discharge hole. D. flue gas temperature after superheaters abnormally decreased or increased temperature difference before and after the flue gas superheater. Serious E. Damaged, the boiler steam pressure drop. F. exhaust gas temperature decreased significantly, the chimney flue gas into a gray or white color. g. draft fan load is increased, the current increased. 2, the superheater tubes blasting process a. Superheater tubes minor rupture, may be appropriate to reduce the load, maintain operation in a short time, this time should be closely monitored for leakage, at the same time, rapid start standby boiler. If the monitoring process fault conditions worsen, it should be shutdown as soon as possible. b. When severe rupture superheater tubes must emergency shutdown.
