bangladashi al boiler compani
For safe operation, the gas bangladashi al boiler compani must have the following security facilities.
1, the ignition control system
Harbin Thermal Power Co., the main city of Harbin is the largest cogeneration business, the company bear the city's heating area of 24 million square meters, to provide heat supply for more than 400 agencies, enterprises and 140,000 residents. Currently, the company is actively respond to the latest environmental standards introduced in China, the group mobilized up and down, stepping up technological innovation, upgrading environmental protection facilities, the project is expected to complete upgrading coal-fired bangladashi al boiler compani at the end of this year.
Harbin Thermal Power Co., the existing five boilers for heating and power generation: where to cogeneration units No. 7,8,9, and the other two hot water boilers. No. 9350 MW units which since 2017 was completed and put into operation, has achieved ultra-low emissions standards during construction. 7, No. 8 is 300 MW units were built in 2005 and 2006, these two units of environmental transformation began in 2013. Harbin Thermal Power Co., according to the latest environmental requirements, environmental upgrading facilities. First, soot emissions transformation, the introduction of advanced electric bag filter, followed by addition of sulfur, in addition to the transformation of nitrate, new burners in addition to the low nitrogen oxides of nitrogen, a wet desulfurization technologies in addition to sulfur dioxide. After four consecutive years of continuous transformation, 7,8 units in 2017, all the transformation is completed, achieve ultra-low emissions standards. For the two 116 MW hot water boiler was built in 2013, it has long been included in the transformation plan. Earlier this year preparatory work has been completed and environmental transformation has entered the bidding process in mid-October to start construction, completed renovation project at the end of December.
Working principle and characteristics of the premix bangladashi al boiler compani a combined module, the working principle: the premix boiler module, based on user needs and design load size, the number of modular units can operate independently of the integral boiler, through the outer chamber temperature, and monitoring the supply and return water temperature change computing, computer-controlled system may control each of a module, the module automatically adjusts the number of start and stop, so that the heat output always matches the actual heat load demand, and to ensure that each module can be kept in optimal combustion conditions, so as to achieve overall efficient operation of the boiler. Second, the main features: 1, saving fuel. Most ordinary boiler when there is a low load operation, the actual thermal efficiency is much lower than the thermal efficiency of the design defects, when the load fluctuations, will cause energy waste. Premix combustion boiler module due to its simple behavior control, with adjusting the load change fast, flexible, thermal efficiency can be always maintained at 95% (90%), thereby achieving energy efficient operation. 2, stable, easy to operate. Because of the unique premix module boiler operation mode, easy to automate the process of running the operation. Automatic control system of the boiler installation, full automation can be achieved during operation according to the set parameters, the operator is reduced. 3, transportation, easy installation, small footprint. Since the dismantling of the boiler can be like building blocks in combination, therefore, greatly facilitates transport and installation, reducing the footprint, and without foundation boilers, require a lower storey of the boiler room. 4, easy to maintain. Due to the simple structure of the boiler itself, no drums, and other ancillary equipment fan, so running failure rate; and achieve low noise operation. 5, each module backup each other without backup boiler, if the malfunction in the heating of individual modules, has little effect on the entire system.
What is worth the bangladashi al boiler compani us to focus and specifically discussed? Boiler RB, which refers to what? Boiler insulation, materials What? How to determine its thickness? As well as, the requirements for the construction of the boiler room, what? In addition, what the problem is related to the boiler? These, for us, is very important and basic, so the following answer one by one, to let everyone have a thorough understanding and correct understanding. 1. boiler RB, which refers to what? Boiler room in the RB, which then specifically, it refers to the rapid reduction of the boiler load. And, it means that when the auxiliary boiler trip due to a failure, it will automatically be reduced to 50% of the rated load matching, that is, half of the rated load, in order to ensure the safety of the boiler. At the same time, control of the boiler, change will occur. How the material and thickness of the insulation layer 2. The boiler is determined? In the boiler, the insulation layer is a very important part, in which the material selection, there are mainly rock wool, ceramic fiber cotton and cotton fibers such as aluminum perchlorate. Wherein, aluminum chlorate is used mostly cotton fibers. As for the thickness of which is determined on, it is determined according to the temperature requirements, and also taking into account the heat losses. For the boiler and pipes, in general, a thickness in the range of 100-200mm.
