LPG boiler is provided with a manhole at the top and a hand hole at the lower side, which is convenient for inspection and maintenance. LPG steam boilers before and after the observation of fire holes, you can observe the combustion in the furnace. The front and rear flue boxes of the boiler adopt movable double seal structure, which is convenient for inspection, maintenance and cleaning inside the boiler. Explosion-proof door is arranged in the rear smoke box to ensure the furnace deflagration timely pressure relief. Wet back, waveform furnace structure, heating surface symmetrical arrangement. Effectively reduce the thermal stress of the boiler, and improve the safety and life of the boiler. The heat transfer effect of the screw pipe is improved by using the screw pipe.
This series of industrial gas fired boilers are made of high quality special steel to make the combustor of the corrugated furnace, which has good thermal expansion characteristics on the basis of increasing the heating area. The thermal efficiency of the main engine is increased by 1.7%, and the service life of the structure is long. Wet back structure is adopted in the backburn chamber to strengthen the convection heat transfer effect, reduce the exhaust temperature and improve the thermal efficiency of the boiler. The high temperature flue gas is surrounded by water space, which reduces the thermal fatigue of tube plate and increases the life of boiler body.
LPG steam boilers operation is stable and reliable, when the boiler runs to the upper limit of the working pressure value, the burner stops burning, after a period of pressure decline, restore the pressure value, it can automatically enter a period of combustion, restore its automatic regulation performance. The ratio of damper and fuel quantity is adjusted according to the composition of flue gas when the boiler is put into initial operation. When determined, it will not be changed in long-term operation in the future. The low position combustion chamber is used to make the safety range of the boiler water level larger, the steam space of the boiler is larger, and the steam quality is well guaranteed. Fin-type steel tube energy economizer is arranged at the tail with high heat transfer efficiency. The smoke temperature after the energy economizer is less than 150℃ to reduce fuel consumption.
This series of steam boiler is widely used in rubber factory, textile factory, food factory, brewery, printing factory, pharmaceutical factory, chemical plant and other industrial places. Adopt internal combustion wet back flue gas three return structure, reasonable and compact structure. The gas fired boiler adopts screw pipe, inside the spoiler, strengthen the heat transfer effect, greatly improve the thermal efficiency. Front and rear removable smoke box door, convenient boiler maintenance and overhaul. The body can be galvanized according to the need to provide clean domestic hot water. Condensing heat exchanger can be added to the flue gas outlet to reduce the exhaust temperature and absorb sensible heat and latent heat in flue gas, and improve the efficiency of the boiler.
LPG steam boilers automatic operation By setting the start and stop temperature of the burner and circulating water pump, the control system runs automatically according to the set conditions. And realizes the display of system working conditions and the temperature of outlet and return water. Displays alarm information in case of failure. Manual operation In the manual state, the circulating water pump and burner can be operated directly. When a fault occurs, corresponding instructions can be made to refuse manual operation to ensure system safety.
