connecting hot water boilers in line
2, meet environmental requirements, improve the environment.
If the gas fired boiler to boiler, boiler output in case of the same, C02 emissions can be reduced by more than 26%; S02 substantially zero; the NOx emissions by at least 33%; ash and soot are reduced to zero; Green environmental protection effect is remarkable.
3, reasonable program of boiler rehabilitation programs must be simple and easy to do: less investment and quick, short construction period. Accordingly, the content of the boiler according to the transformation in the transformation of the less the better, and can be taken to change only the furnace combustion apparatus, part of the basic structure of the transformation range as not to exceed the boiler body.
4, the reliability of the gas supply when the gas supply is not reliable, the fuel system may be provided. If you need to re-consider leaving room for coal-fired boilers, should select the appropriate way to meet the requirements of gas.
In order to further standardize Xuzhou City, air pollution control construction and operation management, protecting and improving the quality of the environment, prevent environmental pollution, introduced the "Xuzhou City in 2019 the thermal power industry, air pollution control basic norms." For the raw fuel storage, handling, transportation, storage byproducts, transport, collecting and centralizing the flue gas treatment systems and other aspects of the essence of the specific requirements.
First, all coal-fired units desulfurization facilities required to install, in addition to coal-fired circulating fluidized bed boiler units to be installed denitration facilities, coal and biomass fuel units to be equipped with efficient dust removal facilities. Desulfurization, denitrification, dust removal device processing capabilities must meet the production needs, we must be able to maintain long-term stable operation, must be professional manufacturers design, produce qualified products. Exhaust pipe shall be provided with permanent sampling ports and in accordance with national and regulatory requirements related to the construction of Jiangsu Province.
Second, the boiler produces air pollutants must be in accordance with national standards and requirements related to Jiangsu Province, construction of flue gas collection systems and centralized purification facilities, flaring has been the implementation of "coal to gas," "dry FGD" and included in discontinued closure plan outside the coal boiler, and the rest are required to install the cooling and dehumidification systems, and to ensure proper operation.
In the past, a considerable period of time, due to various heating design emphasis on safety considerations, the design heat load calculation results are generally much larger than the actual value required, so multi-radiator, connecting hot water boilers in lines, large pumps, large diameter, first heaven and earth form a "big horse car" situation, low-load, high-volume operation is widespread. This is due to the mismanagement of the designer heating operation, fireman low level of technology factors affecting heating do not know enough to worry about heating is not, will not dare to cut down the heat load, resulting in equipment is still too large, creating a vicious cycle. Over the years, through a lot of practice and testing, in terms of common understanding has been great progress in the actual design and the increasingly close. (C) the low level of management is the main cause of high energy consumption.
Requires food factory boilers have what? Requires food factory boilers have what? Boiler plants for food refers to water heated to a certain parameter and production of industrial boilers, high temperature steam boiler drum heating water into steam, heat from the furnace of fire, is the principle of a steam boiler. Food boiler plant using special equipment. Design, processing, manufacturing, installing and using the boiler must be supervised by technical supervision departments. Users can only be used after obtaining boiler boiler license. It works food factory boiler: heating equipment (burner) release heat, radiation heat transfer is first absorbed by the water wall. Wall boiling off a large amount of water steam into the steam separation drum (excluding the DC furnace). Separated saturated steam into the superheater by radiation and convection, and continues to absorb horizontal roof and smoke and flue backpass heat the superheated steam reaches a predetermined operating temperature. With boilers for power generation typically reheater, steam heated to high pressure cylinders for completion. Reheated steam reheated in the reheater, the low-pressure cylinder to continue power generation. Food plant boiler requirements: 1, before the food factory boiler fire, you should check valves pipes, steam pipes, pressure gauge, safety valve, water gauge, drain valve intact. 2. Boiler water softening food plants should be kept clean. Do not allow the use of grease. Water level gauge glass tube should be installed rugged protective cover, outside should be kept clean. Each class should punch once, to see how quickly the water table face up or down. If the water meter in the water stagnation and do not jump during operation, should immediately identify the reasons, in order to prevent the formation of false water level.
