The steam used in the steam generator of the hotel laundry is usually 0.4~0.6MPa saturated steam. The working temperature of steam is not very high. Gansu Energy saving steam generator The steam boiler of the hotel requires high steam efficiency due to operating costs, so it can save operating costs. The area of the hotel is relatively limited, so the steam boiler with small floor area must be selected. In order to control the investment cost and heat loss of the steam pipe, the steam boiler is usually placed on the side of the laundry room. vertical Energy saving steam generator factory The steam equipment in the hotel laundry room can only be turned on when washing, not when washing. Therefore, the steam generator is required to start steam production quickly. Laundry equipment is sometimes opened a lot and sometimes less, so the steam boiler is required to adjust the steam volume within the specified range.

After the cold furnace of oil fired and gas fired boiler is ignited, the speed of temperature rise shall be controlled at 10 ℃/hour, mainly because the viscosity of oil temperature is large when it is cold, and the flow rate in the heating surface pipe of the whole equipment is relatively low. Gansu Energy saving steam generator The oil film on the pipe wall is thick, so the heat transfer condition is poor when in use. If the heating speed of oil and gas fired boiler is too fast during use, it is easy to make the local oil film temperature too high. The equipment is in the stage of driving away the residual moisture and moisture contained in the heat conduction fluid in the system within the temperature range. vertical Energy saving steam generator factory In oil and gas fired boiler, when the steam exhaust volume at the vent pipe of the expander is relatively large, there will be water hammer at the bottom of the equipment. In this way, the vibration of the pipeline will accelerate, and when the swing amplitude of the pressure gauge pointer in each part of the equipment is large, the temperature rise will be stopped and the constant temperature state will be maintained.

Energy saving. The waste heat boiler adopts new heat exchange fins and heat exchange elements, which enables full heat exchange. The boiler efficiency can be increased by 6~15%, and the condensate drainage structure can fully recover the latent heat in the flue gas. The energy-saving effect is remarkable. Gansu Energy saving steam generator Due to the special structure, the total pressure drop is small and the power consumption is small, that is, the smoke pressure drop is small and meets the system requirements. beautiful. Due to the use of efficient heat exchange elements and reasonable structural configuration, the waste heat boiler has the characteristics of compact structure, small size, beautiful appearance, etc. Durable. Heat exchange tubes of waste heat boiler facilities are made of stainless steel aluminum fins for corrosion prevention. vertical Energy saving steam generator factory The thermal stress, anti-corrosion performance and strength are fully considered when the equipment is manufactured, which can ensure the safety, reliability and stability of the equipment, with a service life of more than 25 years.

The waste heat recovery of flue gas can not only be used for heating or power generation to achieve energy-saving effect, but also can be beneficial to environmental protection and achieve dual effects of energy conservation and environmental protection. Gansu Energy saving steam generator In general, the important equipment of waste heat power generation is waste heat boiler, which mainly uses heat or combustible substances in waste gas, waste liquid and other working medium as heat source, and produces steam mainly for power generation. There are many ways to recover waste heat from flue gas of waste heat boiler. Generally, comprehensive utilization of waste heat is followed by direct utilization and indirect utilization. vertical Energy saving steam generator factory Generally speaking, if heat sources are needed in the process, the waste heat utilization is mainly comprehensive utilization. First, the heat source is recovered and fed back to the process for reuse. If there is any surplus, it can be used for power generation or as the heat source for central heating; If there is no surplus, it will be directly used instead of being used for power generation; If the process does not need more heat sources, then indirect use, mainly power generation or public heating.

The air storage tank in the air source system shall be installed behind the rear cooler, so as to prevent oil vapor and liquid water from gathering in the tank and reduce potential safety hazards as far as possible; The lower temperature of other air stored in the tank can also reduce the volume of the body. Gansu Energy saving steam generator When connected with screw compressor and other air supply equipment, the air receiver can be installed behind the dryer. At this moment, the air entering the air receiver is dry and there is no condensate in the tank. The air tank is a pressure vessel, and each air tank shall be equipped with safety valve, pressure gauge and other necessary safety supervision equipment. vertical Energy saving steam generator factory The application and maintenance shall strictly comply with the relevant provisions of pressure vessels; The air tank shall be equipped with a manhole or hand hole for maintenance, and the lower part of the tank shall be equipped with a drain valve, which shall be regularly drained; The air storage tank is usually installed outdoors, so it should be protected from direct sunlight and there should be no high temperature heat source nearby.
