steam boiler saturated steam superheated
The boiler fan is selected according to the type and specification of the boiler, and the ventilator can play two different roles in this field, but the working principle of the ventilator is the same.
Condensate recovery system can be divided into open and closed recovery system recovery system.
Recovery system is open to a condensate recovery tank to the boiler, the condensed water recovery and utilization in the process, one end of the recovery pipe is open to the atmosphere, i.e., the condensed water collection tank is open to the atmosphere. When the lower pressure of the condensed water, can not be reached by the pressure from recycling properties, high temperature condensed water pump pressure-feeding. The advantage of this system is that the device is simple, easy to operate, a small initial investment; however, a large area of the system, resulting in low economic efficiency, larger environmental pollution, and since the condensed water is directly in contact with the atmosphere, dissolved oxygen concentration in the condensed water improved, easy to produce equipment corrosion. This system is suitable for small vapor supply systems, a small amount of condensate, small amounts of secondary steam system. When using this system should minimize emissions of secondary steam.
Environmental trends at this stage of the boiler, energy-efficient premise is the development of environmental protection industries, all pollute the environment, feel free to use the production of non-renewable resources are not allowed, boiler industry is the same. Today we'll look at the development trend of environmental protection boiler. To further strengthen air pollution control, safeguard people's health, and improve ambient air quality, enhance the level of ecological civilization construction, the boiler is also developing towards the direction of environmental protection. At present, the boiler industry in China energy-saving environmental protection industry, the presence of small-scale enterprises, poor financing, technological research and innovation is not enough, the market order is not standardized and other issues. Insiders suggested that the development of energy-saving environmental protection industry can explore energy conservation and environmental protection equipment manufacturing and modern service integration model of development, to encourage the advantages of energy saving equipment manufacturing enterprises through mergers and acquisitions and other ways to extend upstream and downstream industry chain, formed a set of engineering design, equipment manufacturing , operation and management in one mode of operation, promote the rapid development of environmental monitoring, environmental engineering consulting and other related services. With dwindling non-renewable resources, the rapid rise in energy prices, coupled with the nation and the world the importance of environmental protection, energy saving, since the five-year plan, building a resource-saving and environment-friendly slogans have been proposed, the development of boiler market began to develop from extensive development to energy saving and environmental protection.
More than 40 representatives from various industries across the country gather together in the group headquarters, systematic training and study and visit. Training excluded from the boiler system principles, common faults, maintenance meaning three aspects, the system elaborated from design, manufacturing to installation, commissioning, maintenance matters should be noted that several stages, delegates took the floor, the actual situation of the unit, asked in detail about the future direction of maintenance work required effort.
