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. Jinan Natural gas 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. small-scale Natural gas steam generator how much 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.

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. Jinan Natural gas 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. small-scale Natural gas steam generator how much 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.

Oil gas boilers have obvious characteristics. The main fuel is oil or gas. According to their functions, they can be divided into steam boilers and hot water boilers. Most of them are designed with large furnaces, with thermal efficiency of more than 98%. At the same time, they also have the characteristics of fully automatic and safe operation. Jinan Natural gas steam generator Generally speaking, oil and gas boilers adopt excellent boiler body design. WNS horizontal boiler adopts wet back three return structure, which can reduce the exhaust gas temperature and make the boiler thermal efficiency reach more than 90%. Therefore, the combustion efficiency is relatively high, greatly extending its service life. small-scale Natural gas steam generator how much In addition, in the design of oil and gas boiler, there are often hinged front and rear smoke boxes. The maintenance method is simple. Most of them are insulated with light aluminum silicate fiber to reduce heat loss. The external use of all stainless steel plate skin improves the appearance quality. In addition, the oil and gas boiler is equipped with an excellent combustion machine, which greatly improves its stability. The combustion machine has an automatic purging function, It can also prevent deflagration during ignition.

The waste heat boiler greatly improves the utilization rate of heat released by fuel combustion, so this kind of boiler saves energy; Fuel oil, gas and coal combustion generate high-temperature flue gas to release heat. The high-temperature flue gas first enters the furnace, then enters the waste heat recovery device of the front smoke box, then enters the pyrotechnic tube, and then enters the waste heat recovery device in the flue of the rear smoke box. The high-temperature flue gas turns into low-temperature flue gas and is discharged into the atmosphere through the chimney. Jinan Natural gas steam generator Conditions conducive to quick startup of waste heat boiler: (1) The waste heat boiler adopts forced circulation, which has the priority of quick startup. (2) The flue gas baffle is hydraulically controlled, which can be used to adjust the sky in principle. The flue gas flow into the boiler is reduced. (3) The adjustable guide vane at the inlet of gas turbine can not only adjust the flue gas flow of gas turbine, but also increase or decrease the exhaust gas temperature of gas turbine through the selection of IGV temperature control mode. (4) The steam turbine bypass is designed for the rated evaporation capacity of the boiler. (5) The welded bends and headers of each heating module of the boiler are in the boiler. (6) Similar boilers in other gas turbine power plants can not be reduced when starting, and can be used to adjust the main steam pressure of the boiler. Outside the wall, contact with high-temperature smoke is avoided. small-scale Natural gas steam generator how much Operating experience of gas turbine load, such as simultaneous startup of gas turbine and waste heat boiler (flue gas damper fully open). Under the possibility of quick startup of waste heat boiler, the water level of steam drum and deaerator will lose control after the flue gas baffle is opened.

In daily life, pressure vessels are divided into those in contact with fire sources and those not in contact with fire sources. In fact, pressure vessels also need anti-corrosion in daily life. For the anti-corrosion of pressure vessels, we need to do the following. Jinan Natural gas steam generator First, check the structure of its equipment components, safety valves, bursting discs, emergency vent valves and other collective Yixing pressure tanks to see if there is any corrosion. Once corrosion occurs, measures should be taken in a timely manner. Anti rust paint should be painted before the equipment is used. After use, it should be cleaned in a timely manner to ensure the cleanliness of the equipment. small-scale Natural gas steam generator how much Secondly, it is necessary to protect the safety device of the pressure vessel. The safety device is an important device of the pressure vessel. Good protection should be carried out. Good maintenance should be carried out before and after use. It is necessary to apply lubricating oil and antirust paint.
