The new LSS vertical fuel / gas / methanol steam boiler of Sitong Boiler in 2015 1. The structure of LSS vertical gas steam boiler:
The vertical gas-fired steam boiler is a vertical internal combustion fire tube boiler. The high-temperature flue gas generated by the burner is sequentially flushed from the top of the furnace bladder and the threaded flue pipe inserted with the spiral spoiler, and then discharged into the atmosphere from the lower smoke chamber through the chimney. The boiler is equipped with industrial burners with good technical performance. It adopts advanced technologies such as automatic combustion proportional adjustment, automatic feed water adjustment, program start and stop, and full-automatic operation. Protective function. This type of boiler has the characteristics of compact structure, safety and reliability, easy operation, rapid installation, less pollution, low noise, high efficiency and so on.
Second, LSS type vertical gas steam boiler control system description:
The vertical gas-fired steam boiler uses a fully automatic burner with good technical performance as the main combustion equipment. The burner's combustion program is controlled by a more advanced combustion program controller, which can achieve various functions necessary for the normal combustion of the boiler. In the state, accident state, and extraordinary circumstances, protective furnace shutdown is automatically implemented, with corresponding water level controllers and pressure regulators, to achieve high and low water level instructions, overpressure instructions, and adjustments to ensure that the water level fluctuates within the normal range and the steam pressure is within Within the allowable pressure fluctuation range, the protective stop instruction is realized when the water level is extremely low and the pressure is too high.
Third, the installation of vertical gas steam boiler host:
(2) The determination of the boiler foundation should be based on the local soil quality, and the civil engineering department should redesign the boiler foundation drawing provided by reference.
后 After the foundation of the boiler reaches the strength, it shall be inspected and accepted according to the boiler drawing, and the three reference lines of the boiler as a whole shall be formed:
a. Horizontal reference line—the center of the pot.
b. Longitudinal reference line—base position line.
c. Elevation baseline—You can choose several relevant points around the foundation for marking, and the corresponding offset between each mark should not exceed 1mm.
(3) After the main engine of the vertical gas-fired steam boiler is moved to the installation site, it should first check whether the boiler centerline is consistent with the centerline drawn on the base; whether the normal water level of the water level meter is horizontal; Tight, if there is a gap, you should add horns.
Fourth, LSS vertical gas steam boiler auxiliary machine installation:
The installation of the burner and feedwater pump should be unpacked and inspected in accordance with the supply list before installation, and the installation can only be performed after confirming that the actual product matches the supply list and that the inspection is qualified. After installation, check for jams and air leaks. Finally, turn on the power to test run, and check whether the motor steering is normal, whether there is friction and vibration, and whether the motor temperature is normal.
If the connected flue duct is inconsistent with the design pattern and the length, elbow, and cross-sectional area change greatly, the flue resistance should be redesigned and the working pressure of the burner should be calibrated to meet the actual needs of the boiler.
V. Installation of LSS Vertical Gas Steam Boiler Chimney:
⑴ When assembling chimneys, asbestos ropes should be inserted between the flanges, and the verticality of the chimneys should be checked by hanging lines. If there is deviation, it can be leveled at the flange connection.
拉, the pull wire (wire rope) is tightened with flange bolts. Note that the tightness of the three wire ropes should be approximately the same.
(3) The height of the chimney can be shortened or increased according to the requirements of the environment and local authorities.
Installation of electric control cabinet for vertical gas steam boiler:
The electric control cabinet is the switch button of the burner, water pump, water level alarm, etc. on the vertical gas-steam boiler. After all the power is connected, the box shell should be protectively grounded.
The electric control cabinet should be installed in front of the boiler, close to the wall, so as to facilitate the monitoring of various instruments on the boiler and facilitate the operation.
7. Safety protection device of LSS vertical gas steam boiler:
1.Vertical gas-steam boiler water level real-time monitoring function: Equipped with electronic water level detection device to monitor the boiler water level in real time.
2. Time setting function: Users can freely set the start and stop time of the boiler according to their needs.
3. Leakage protection function: The control system will automatically cut off the power after detecting the leakage of the electric heating element.
4.Water shortage protection of vertical gas steam boiler: When the boiler is short of water, the burner control circuit is cut off in time to prevent the burner from being damaged by dry burning. At the same time, the controller issues a water shortage alarm indication.
5, power abnormal protection function: the boiler immediately stops running.
6.Overpressure interlock protection: When the pressure inside the boiler exceeds the user set value, the burner is prohibited from working and an alarm is issued.
7.Multiple safety protections such as pressure controller, water level alarm, safety valve, extremely low water level alarm, etc.
8.Complete gas valve group and protection system: Provide complete gas valve groups and accessories from filters, pressure regulators, solenoid valves, etc. to ensure the safety of gas.
9, flue gas monitoring device, can automatically monitor the exhaust temperature of the boiler, more conveniently grasp the combustion of vertical gas-fired steam boilers.
