Packing Machine Electric Steam Generator
Small electric steam generator What are the benefits, features? First, electric and gas, fuel oil to generate steam compare the advantages and disadvantages: advantages and disadvantages of gas: Advantages: coal is the most economical energy per kilogram of coal can produce more than 5,000 calories, can produce around 60,000 kg of steam (theoretical value). Both economical than electric, fuel oil and natural gas. Disadvantages: 1, low efficiency, although theoretically per kilogram of coal can produce more than 5,000 calories, but due to the limitations of the gas packing machine electric steam generator and the Boilermakers by human factors, the real heat of the steam is converted to produce far less than the theoretical value, the heat efficiency of around 60%. 2, can not do automatic control, if the device is not continuous steady steam steam that instant steam consumption fluctuations, the steam produced by the boiler with the steam in the bottom of the valley steam equipment can only let go waste. 3, need specialized operators, high labor costs. 4, do not meet the requirements of modern environmental protection, banning small gas boiler is the trend. The advantages and disadvantages of fuel: fuel meets the requirements of environmental protection, the state has not been expressly provided, however, based on current oil prices, its economy has ceased to exist. Per liter of oil can produce more than 18,000 calories, about 60% utilization, we can produce about 10 kg of steam. Which produce one ton of steam costs around 800 dollars (at current prices). The advantages and disadvantages of heating: Cons: Because electricity is converted from the other sources of energy, so the relatively high price point, once electricity can produce about 1.5 kg of steam. Calculated to produce 1 ton of steam costs about 400 yuan or so based on the current average domestic electricity bill. More expensive than gas. Advantages: 1, high efficiency, above 98% heat utilization. 2, it is possible to achieve automatic control device can automatically adjust the operation of the equipment in accordance with the amount of steam vapor apparatus, according to how much power consumption is the amount of steam may be. There is no waste. Particularly suitable for the case of steam is not constant. For example: a user selection of 0.5 t / h of electric steam generator, power is 360KW equipment, operation at full load, the theoretical power consumption of 360 degrees / hour, but if the user one hour using 200 kg of steam only, then only the power 140 degrees. In many industries such as: medical and pharmaceutical industry sterilization, washing and drying equipment, chemical equipment, etc., the amount of steam is intermittent, this situation if you use gas-fired boilers, there will be large
Hot water packing machine electric steam generator in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
9.Steam from the steam drum is sent to the primary super-heater.
10.Steam is super heated to a high temperature and pressure in the primary super-heaters and then moves to the secondary super-heaters.
11.In the secondary super-heaters steam meets the very hot gases exiting the top of the boiler. The steam is heated to its final temperature and pressure before leaving the boiler as main steam. The main steam is sent to the high pressure steam turbine. The steam turbines drive a generator which produces electricity.
12.Steam exiting the high pressure steam turbine is called cold reheat. It is reheated in the re-heater and sent back to the second steam turbine. By the time the flue gas exits the boiler most of the energy in the coal will be transferred to the water in the boiler. The hot gases are cleaned up before they are sent to a stack. Feed-water is generally supplied by condensed steam from the low pressure steam turbine. Large amounts of cooling water are used to condense this steam into liquid water in the condenser.
Three Pass Gas Fired Steam Boiler in Industrial Laundries
As a top steam boiler manufacturer in China, ZG Boiler has been a premier provider of high-pressure industrial gas fired steam boilers for the industrial laundry markets for over 70 years. Our durable and simple horizontal design is a perfect fit for large industrial laundries factory. Because large size industrial laundries also utilize gas fired steam boilers to provide heat to the ironers, heated rolls, hot water storage tanks, and to provide steam using an unfired steam generator. Large industrial laundries are common in healthcare facilities, resorts, high-end hotels, and prisons.
