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.

Details installed gas boiler combustion system that we need to pay attention when installing a gas boiler combustion system, inviting professional staff in advance of the circuit diagram design, so that when installing the status line installation will not appear unreasonable. Also, pay attention to install some fire-fighting equipment, which can provide protection for our security. Unit ventilation should generally remain the total combustion air amount at the rated load. Combustion process controller provides a separate set of contact start-stop control. May be formulated in a variety of burner start-stop loop cascade control relay 10A is a fuse, relay start-stop control stops the control terminal may be connected to the burner, may directly control the power of the burner. Both constant pressure sensor, water power, fuel, gas pressure set value is detected after the automatic controller opens. Time pressure sensor, water supply, oil, gas, and their detection circuit, alarm and found the problem immediately shutdown flame protection, the controller automatically displays the point of failure, an alarm sounds machine. Installation room oil, gas line gas boiler, boiler room should be strictly in accordance with design, specification, and should refer to the burner. Fuel system pressure test after installation is complete, should be 1.25 times the working pressure (minimum test pressure of not less than 0.4MPa). After the fuel pipe installation system should be flushed with water or steam flushing, flushing should have approved technical measures, the number of washing is not less than the secondary blowing, blow up until the clean medium, should be cleared after the purge debris and dead. After installation of fuel system should be oil circulation system-wide test. The gas should be the shortest route to the burner, the air supply pipe diameter must be larger than the constant value parts of the burner duct.

Select the first industrial horizontal 2 tons fired steam boiler to know what parameters? Steam boilers have the following main parameters: 1, Rated evaporation Rated evaporation is power steam boiler, steam boiler is the most important parameter, usually expressed in tons evaporation, that is, we usually say how many tons of boiler. 2, rated steam pressure rated steam pressure means that the steam pressure generated in the steam boiler, generally expressed in MPa or kg. 1MPa is 10 kg, like laundry, all hospitals, factories and the like conventional steam occasions the general use of low-pressure steam 1.0MPa or less. Only when using steam as a power to require the use of high-pressure steam. 3, where the steam temperature of said steam temperature, refers to the temperature of saturated steam. Saturated steam pressure and steam temperature are corresponding. Temperature of saturated steam at a pressure of 1MPa 184 ℃. 4, gas / oil / gas consumption fuel consumption is an important indicator of concern when choosing a steam boiler, which is directly related to the use of the running cost of the boiler. In the operation of the boiler, the fuel cost is very impressive, if just considering the purchase cost of buying a cheap but high energy boiler, which led to the late high operating costs, certain that it will be wasted. 5, the thermal efficiency of fuel consumption with the boiler thermal efficiency of boilers is inversely proportional. The higher thermal efficiency, lower fuel consumption of the boiler. Boiler thermal efficiency expressed as a percentage, the value is a more intuitive. 6, the boiler operating weight, size or location in the election of the steam boiler, it should find the place whether the load per unit area can withstand the weight of the steam boiler, and if there is enough space to place the steam boiler maintenance and reserve space.

2. Oxygen corrosion

For the biomass fuel boiler pressure parts,the water side is mainly electro chemical corrosion,the fire side (or flue gas side) is mainly chemical corrosion.The oxygen corrosion belongs to electrochemical corrosion, it is mainly caused by the dissolved oxygen in water.At room temperature,the dissolved oxygen concentration is about 9.1mg / L,according to the GB1576-2001 “industrial boiler water quality” requirement ,the rated steam pressure should not be more than 1.0MPa,the dissolved oxygen concentration should not be more than 0.1mg / L,otherwise,it is likely to lead to metal corrosion.
