Five coal-fired hi efficiency coal boiler gas boiler should pay attention to change the key to change the coal-fired boiler gas boiler should pay attention to the five key coal to gas project in the current renovation work, is more common in different regions, we continue to time nodes began to carry out, then, for the transformation of coal-fired boiler more standards-compliant, you need to note in particular the following five areas: (1) removal of auxiliary original coal-fired boiler, the boiler because if you want to fit in fuel, after the boiler auxiliary systems that should be a complete set. (2) the installation of blast doors. (3) of the boiler pressure test 1.5 times the working pressure. (4) in particular, to note that choosing the right matching burner, because the boiler during operation, the combustion machine is good or bad, is one of the important factors that affect the efficiency of the boiler. (5) In general, we should not try to change the pressure of the boiler body member portion, to make only a partial transformation of the furnace wall and the furnace arch. Of course, coal-fired boiler gas boiler change relatively strict, need to take into account the points will be more, just above these aspects must be considered in place of the step, which is to facilitate the follow-up work. In addition, the renovation work, if that time coal-fired boiler using some of the more than ten years or even longer, it is recommended to consider the purchase of a new gas boiler.
In view of the possible near-term benefits, ZG recently funded an assessment of coal fired power plants equipped with three different combustion systems: Kinds of coal, Circulating Fluidized Bed (CFB), and biomass fired circulating fluidized bed. The purpose of this study was to establish, through engineering analysis, the most cost-effective performance potential available through improvement in the steam conditions and combustion systems.
Development of CFB for power generation has been ongoing for several decades. At the end of the 1970s,First introduced CFB combustion technology originally developed for heterogeneous reactors, to the field of coal combustion. CFB operation is characterized by rapid gas–solids mixing, reactions, and heat transfer, all of which create an environment in which low-grade solid fuels can be stably burned at 800–900°C. At these relatively lower temperatures, NOxformation and emissions are much lower than what is observed for PC combustion. In addition, limestone additives can be combined in the hi efficiency coal boiler to capture the SOxin situ. Therefore, CFB offers the least expensive means to control NOxand SOxemissions from coal combustion. Other environmental benefits, such as waste reduction and a smaller carbon footprint, can also be achieved through cofiring coal with biomass or waste. As CFBs are inherently fuel flexible, they can readily accept lower rank fuels that can be varied over time pending availability and other factors.
Subsequently, the delegation visited the company's hi efficiency coal boiler cleaning laboratory, technicians demonstrated to the delegation of the company's latest product boiler operation, and use of DCS control system in the laboratory trace data. Mr. Liu to our boiler products to achieve nitrogen oxide (referred to as NOx) emissions below 18 mg or less, is widely used in Beijing APEC venue, the Central Authority and other countries prefix institutions and other international occasions expressed a high degree of praise and encourage.
