gas fired fire tube hot water boilers
Xiamen Rui Yi Hotel is available straight left Gulangyu the most beautiful views of the BRIC countries delegations designated top hotels, the best location in the heart of Xiamen, modern trends and classic style pavilions. The hotel features well-appointed room service, fashion and superior restaurant, bar, meeting rooms and a gym, swimming pool and other recreational facilities, people feel contented and comfortable. Projects and programs as Xiamen Rui Yi Hotel Xiamen City landmark hotel building, attaches great importance to environmental protection philosophy, which party fast boiler manufacturing philosophy coincide. In late 2016, the two sides signed an electric steam boilers for hotel supplies disinfection work, since the electric steam boiler, any security incidents never happened, Rui Yi Hotel ensure normal operation.
Why fired fire tube hot water boilers heating more energy efficient and environmentally friendly Henan fast boiler small as we explain energy saving boiler heating hot water boilers are generally used, but must be less than normal application process steam. Biomass boiler categories: biomass boilers and vertical columns of biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. Such energy conversion is steam boiler facilities, the kinetic energy of the oil in the heating furnace has a type of chemical energy, electromagnetic energy, heat energy, etc. smoke, and after converting furnace, must be provided externally output energy vapor, hot water, or inorganic heat carrier. Because it more energy efficient than the steam boiler, more environmental protection. First, the level of consumption in gasoline and diesel, heating hot water boiler steam boiler heating savings ratio of 20% to 40% of gasoline and diesel, this amount is very huge. Summed up two reasons: First, it does not damage the condensed water and re-volatilization of calories, and second, water heating line material according to heating unique application, line as thin as possible to meet the requirements, the damage small calories. Great heat damage to steam heating line because the vapor leak caused. Hot water boiler must be only a small amount of basic waste water. Gas steam boiler combustion method underlying the choice of machine, two round configuration, sufficient to ignite fuel, and the smooth operation of the boiler occupies less space, with the spoiler inserted smoke tube, ease exhaust rate, change to enhance calorie, high calorific value furnace, Also reduce customer application takes advantage of warm water handy to be able to adjust the quality of the water temperature. When the outdoor temperature is low, water temperature must be raised to account for everyone's need. When the outdoor temperature is higher, it is possible to reduce the temperature of boiling water, that we must be able to consider, but also over the green environmental protection. System maintenance and low efficiency. Hot water boiler can be tens of kilometers in area than the heating, such as heating furnace in this line have a very nice feature. Although the central heating water on the whole there are some shortcomings, but even more economic benefits, environmental protection and the role of good. Hot water boiler characteristics of the enterprise producing high-quality, long-life, reliable operation. Our warm reception to buy!
How to make boilers more energy-efficient? (Common measures) 1. boiler design of energy-saving measures (1) boiler design, first of all should be a reasonable selection of equipment. In order to ensure safety and energy conservation in the industrial boilers meet user requirements, should be due to self-select the appropriate boiler design boiler type in accordance with scientific and rational selection principles. (2) when the boiler selection, but also the right choice should be based on the type of boiler fuel boiler, industry, geographical install a reasonable choice of fuel type. Reasonable blending the coal moisture, ash, volatile matter, particle size and other combustion equipment meet the requirements of the importing boiler. At the same time, we encourage the use of new energy sources such as straw briquettes as an alternative fuel or blended fuels. (3) In selecting fans and pumps, to select a new type of energy-efficient products, can not choose backward out of the product; boiler operating conditions by matching pumps, fans and motors, to avoid the phenomenon of the "big horse car", the current inefficient use, a large auxiliary energy consumption, should be modified or replaced with energy-efficient products. (4) a reasonable choice of parameters boilers generally at efficiency of 80% to 90% of the maximum rated load, as the load decreased, the efficiency also decreased. Capacity boilers generally used with greater than 10% of the actual vapor on the line, such as when the selected parameters are not exactly according to the standard series, the boiler can choose a higher gear parameters. Auxiliary boiler selection also refer to the above principles, to avoid the "big horse cart." (5) reasonably determine the number of boiler principle is to be considered normal boiler maintenance shutdown, and pay attention to the number of boiler boiler room, no more than 3 to 4 units. (6) a boiler economizer SCIENCES designed to reduce heat losses and improve the thermal efficiency of the boiler, economizer heating surface disposed in the boiler backpass, boiler feed water is heated by heat of the flue gas, to save energy, the installation Xingmei after, a feedwater temperature increase the temperature difference between the boiler water and feed water is reduced, reducing the thermal efficiency of the boiler feed water is generated. Countries: where <4 t / boiler flue gas temperature is not greater than 250 ℃; ≥4 tons / boiler flue gas temperature is not greater than 200 ℃; ≥10 tons / boiler exhaust gas temperature is not greater than 160 ℃, province or should be installed coal is.
Industrial boiler energy-saving technological transformation of existing problems in industrial boiler energy-saving technological transformation of Question 1, the lack of innovation, application of energy-saving boiler mature, molding technology and equipment, such as: increased flue gas heat recovery unit, blowers inverter , condensate recovery and other conventional energy-saving measures is essentially a general condition; and the need for structural changes in energy-saving measures, such as fractional bed combustion of coal and boiler furnace arch transformation techniques, etc., are rare; as transformation project new principle, a new device, oxyfuel technology, high temperature air combustion technology, spray pulverized coal combustion technology (+ supernatant layer combustion boiler combustion mode), condensing heat recovery technology, new energy technologies dust ash and water treatment equipment, is very few. In general, innovation is not enough, the technical content needs to be improved. 2, part of the boiler is not fully considered in the transformation process, but simply changing the burner, the combustion gas flow distribution and does not match the corresponding surface of the heating boiler, the boiler furnace wall insulation and sealing transformation. There is poor combustion boiler, insufficient output, higher exhaust temperature problem, can not achieve the purpose of energy saving. 3, the waste heat boiler using high temperature organic heat required for thermal processes, a boiler generally at 200 ℃ 300 ℃, the exhaust gas temperature of the boiler is usually too high, excessive. In order to meet requirements of energy saving, companies often mounted in the boiler backpass evaporator or a hot water tank, flue gas waste heat recovery, reducing the exhaust temperature. But most of the heat generated in the production process does not require little energy. 4, statistical analysis of experimental data shows that there are many problems inefficiencies run natural gas boiler. The main concern of automatic combustion control, early production debugging is not in place, and so on. Gas boiler gas and incomplete combustion abnormal increase in heat loss caused by high temperature exhaust gas is the direct cause of poor operating efficiency. However, the use of clean energy natural gas boiler, generally higher thermal efficiency, energy saving difficult. Corporate restructuring investment funds enthusiasm is not high.
