steam generator used in laundry equipment
Gas heating boiler in the choice of which areas need attention construction, industrial, life most needs to heating boilers, hot water boiler then what the election or steam boiler heating? How much tonnage, how many? And how to make choice boiler energy-saving and environmental protection? these questions will undoubtedly cause great distress customer, the following solve these problems, we can do a simple discussion, consider providing some feasible ideas. A. How to determine the tonnage and the number of boilers must first be calculated from the area of heating and domestic hot water heat demand of the total amount for this issue. Meanwhile, in the calculation of the process, also taking into account factors external architectural features heating areas, temperature characteristics, the peak water heating, etc., due to local conditions at the time. Then, after completing a comprehensive evaluation, will be able to consider the issue of tonnage and number of units furnace, then how should the election, which requires analysis to analyze the results of previous projects using features of the boiler, but also to figure out the actual boiler operating efficiency, as well as tonnage and heat supply matches demand real problem customer site. II. When selected gas heating boilers, steam boilers or hot water is selected by boiler application analysis of many companies, both on a simple comparison, you will find hot water boiler will be energy efficient than steam boiler, so if there are energy-saving project demand, suggested the use of hot water boiler. Of course, both need something like hot water and steam needs, you need to hotels, hospitals and other places to determine the actual situation. If a large amount of hot water heating system, requires a small amount of steam, it is recommended to install a small steam boiler or steam generator used in laundry equipment outside of the hot water boiler, in order to meet the needs of a small amount of steam. For example, a hospital or a star hotel's steam demand does not exceed 30% of the total heat demand. According to practical experience, low load operation efficiency of the steam boiler and attenuation is large, the system energy losses. Final energy efficiency is only about 60%, serious waste of energy. III. How to select energy saving gas heating boiler from the heat required systems, combustion systems, control systems and other consideration, and that is in heat transfer systems, taking into account the use of materials heat exchanger, steel, copper or iron, which according to their comparative property, currently used is copper; boiler combustion system is the key to determine whether the device is energy saving. Combustion methods currently used are: premix combustion method, atmospheric premixed combustion and the diffusion combustion method. But just in terms of energy savings, premix technology would be more advantageous, it pre-mixed air and gas, multi-mode radiator heat, the intensity of the heat transfer improved. The advantage of using this method is that the combustion flame combustion clearer, and higher thermal efficiency.
Combined heat and power (CHP) introduction
Cogeneration, refers to the heat and power plant in the same joint together, shorted as CHP (combined heat and power). CHP plants have been ordinary waste heat to be utilized to provide cheap heating heat for industrial and household use, which can greatly improve the thermal efficiency. Typically thermal power, its efficiency is about 30 to 35%. This means that for every 1 mega-joule energy output, there are two mega-joules of heat wasted. This part of the heat of re-used to heat water, fully meet the heating needs of the plant and the residential area near the plant. CHP usually drive a steam turbine generator, and the exhaust heat is used to complement the existing boiler plant, the total efficiency of up to 80%.
The technical characteristics and oil-fired boiler and fuel oil product boiler has three pressure controller, automatic start and stop based on the set pressure value of the pilot burner, adjust the steam pressure within an allowable range of pressure fluctuations; boiler fuel together with the corresponding level control , a water supply and automatic water level indication, alarm, adjust the water level in the normal range. Having a vapor pressure ultra-ultra-low level ﹑ ﹑ ultrahigh level, and indicates to achieve protective stop alarm low level. The boiler has a compact, reliable, practical operation becomes simple, quick installation, less Huanjingwuran, low noise, high efficiency. Technical characteristics of the fuel boiler 1, steam production fast: a small volume of water, heat quickly, heating boost. After 5 minutes start the ignition need to supply steam, with a high efficiency of the separator, to ensure product quality steam. 2, safety: automatic selection of the control, the actual operation is simple. A key to start, the boiler that is self-starting. Combustion, water level, temperature and steam pressure are automatically adjusted to ensure safe operation. 3, easy to install: the whole boiler in the factory assembly, commissioning complete supporting facilities. The boiler in place, only the access of water, electricity, oil, gas and sewage pipes can be put into operation. 4, good sealing performance: dust entire channel inside the boiler body, good security. 5, high thermal efficiency: at the outlet of the boiler fumes are layout heat recovery device, further reducing the temperature of the exhaust system, the lifting more than 2% boiler efficiency. 6, a good pair of combustion systems: the use of world-renowned brands burner, high combustion efficiency and improve boiler efficiency, operational cost savings * bottom line. Oil-fired boiler by the upper body and the lower part of the chain grate composition, consisting of the construction site on the spot. Arranged behind the boiler air preheater. Converted into a high temperature combustion of soot in the furnace are sucked away part of the heat, smoke chamber diverted into the convection heating surface heat exchanger, after the boiler combustion air required for heating the air preheater, induced draft fan and then through the smoke filter gas supplied to the chimney into the atmosphere. The main purposes: as a heat source temperature below 350 ℃ various temperatures, to a wide variety of needs for various fields of high-temperature heating or drying; high temperature, low pressure; * temperature, energy usage rate. Match the steam generator used in laundry equipment and 0.6MPa or less saturated steam, for customer use. The main features of oil-fired boiler: 1. product design, manufacturing, testing in strict accordance with "organic heat carrier furnace safety technology supervision order", GB / T17410-2008 "organic heat carrier furnace" standards, procedures implemented and national special equipment safety supervision by the institutions examination, safe and reliable. 2. Boiler Heating Surfaces selection argon arc welding of full penetration welding, and by X-ray inspection, hydrostatic test pressure keeping qualified to ensure a high welding quality through the national standard. 3. Using unique patented technology arts, Double tube furnace using closely spaced, set top ceiling tubes, both surfaces of the heated tube, the high temperature increases the residence time of soot in the furnace, high thermal efficiency, improved boiler use period. 4. tail heating surface of boiler design arts unique technology and unique staggered arrangement improves the heat transfer coefficient of the boiler to eliminate the problem of heating surface fouling. The realization of automatic coal slag, the matching frequency control fireman art can be reduced to a person to operate. 6. Mechanical forced combustion, special furnace arch design, combustion, smoke and dust, environmental effect. 7. easy to install boilers, overall investment is relatively small, cost-effective.
