Classification and selection fuel gas boiler thermal control system: a fuel gas heat boiler control system classification (1) a combination of an electric system for an electric meter instrumentation system consists of relays, time relays, the relay program composed of program control and interlock system; or by the electronic control and intelligent digital series instrument, measuring instruments display, sound and light alarm monitoring instrumentation and control system and other components. Electric instrumentation system design experience mature, the price is cheap, but it is difficult to achieve system redundancy, remote data transmission, maintenance is more difficult, more difficult to implement advanced control methods. Electric meter system is mainly used for small boilers, but the electronic control Applications for closed-loop regulation of decreasing almost been replaced by intelligent multi-function instrument, the following sections mentioned electronic control just want to take advantage of familiar industry and series instrument combination that's widely used to illustrate the principle of regulating system and constitution. (2) programmable control system programmable control system is the core of programmable logic controller (PLC). Programmable logic controllers are widely used in the initial control, since the 1990s has increased the ability of process control, the programmable logic controller in the field of process control applications more widely. Programmable controllers typically use a modular structure having a self-diagnostic and communication capabilities, can completely replace the relays, time relays, and a relay circuit for the logical functions. In a continuous control, input analog may be, for performing mathematical operations, it is easy to implement advanced control functions electric instrument system difficult to achieve. (3) The microcomputer control system: This system is Direct Digital Control (DDC) system, which is the core of the microcomputer. Figure 7-1 is a block diagram of a microcomputer controlled system. Microcomputer automatic control system can show you all of the parameters of boiler operation, and dynamic display of important parameters and alarm recording boiler operating conditions, the storage boiler operation, timing and instant print reports. The microcomputer-controlled powerful computing system, may be implemented to optimize the combustion control and other advanced control can also be linked into a network, to realize long-distance data transmission. The microcomputer disadvantage automatic control system reliability is somewhat less, still generally indicate and configure the necessary backup manually-operated unit. But with enhanced anti-jamming performance of industrial microcomputer (IPC), the reliability of microcomputer automatic control system will continue to improve. (4) Distributed Control System (DCS), also known as Distributed Control System distributed computer control system, the production process is centralized monitoring using computer technology, communication technology and redundancy, operation, management and decentralized data acquisition and control of a new types of control technology. Distributed control system is powerful, high reliability, generally used for large boilers and boiler group control. Over the years, DCS vendors in order to meet market demand, the introduction of small flexible mixing process for a variety of applications and devices open control system integration control, more suitable for medium-sized boiler DCS, such as HONEYWELL company's S9000 systems.
Jiangsu chemical plant electric steam boiler how much the price of electricity in Jiangsu chemical plant steam boiler price how much? For many chemical plants present, many based on the use of gas-based, but for some local chemical plant, the local gas is not rich, natural gas steam boiler can not be used up. So, there are a lot of fast boiler manufacturers to consult electric steam boiler price. Also the choice of electric steam boilers must be to carry out a wide range of contrast. Recently, a chemical plant for consultation need to purchase an electric steam boiler fast boiler, but for specific models and specific tonnage is not very understanding. Therefore, the technical staff want fast boiler for their own chemical enterprises accounting model and price of. Fast boiler technician for the actual situation of the chemical understanding of the resulting data indicates that the chemical plant with a 2-ton electric steam boilers possible. At present, the model of boiler in square fast, priced at 200,000.
The development of high quality electric boiler for central heating is the coal furnace laid off in line with the trend of the times, and the electric boiler is born in the air. Now many smoky smokestacks have been dismantled and gradually replaced by electric boilers. Electric boiler, as a new heating equipment with electricity as energy, has been recognized by the market since its emergence. Especially with the development of the times, energy conservation and environmental protection will be the trend of development for a long time now and in the future, and the electric boiler is just in line with this characteristic, so it will not be eliminated by the times and will not be rejected by the market. At the same time, as a green energy equipment by the country's strong support. The traditional boiler market is not only restricted by the scale of investment and the development of national economy Constraints, but also affected by energy and environmental policies. Up to now, many large and medium-sized cities have reduced coal-burning boilers, and more attention has been paid to circulating, high-efficiency, energy-saving and environmental-friendly electric boilers. There is no doubt that electric boilers using clean and pollution-free fuel technology will be the mainstream of the future boiler market. In order to meet the needs of the market, electric boilers are also constantly developing and improving. Especially the beautiful use of domestic electric boilers, not only heating, but also very good decoration, deeply loved by consumers, the development prospects are naturally a great deal.
Anyang City Minshan Nonferrous Metal Co., Ltd. is a collection of urban mining, renewable resources, energy as one of the economic wisdom of cleaning companies, mainly non-ferrous metal extraction and processing work. Company to conserve energy, cleaner production for the purpose of this concept coincides with the fast boiler. Thus, when the company in the purchase of the product boiler, and fast boiler almost hit it off, by the party to provide a fast 6 tons of steam integrally condensing gas steam boiler (WNS6-1.25.Y.Q).
