cost for electric boiler

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mainly used for small boilers, but the electronic control Applications for closed-loop regulation of decreasing almost been replaced by intelligent multi-function instrument, the following sections mentioned electronic control just want to take advantage of familiar industry and series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.

Electric boiler automatically adjust the air-fuel cost for electric boiler premixed combustion, the combustion air conditioning unique technology, electric boiler automatically adjusted according to the load demand air-fuel ratio, the air and gas remain in excellent mixing ratio to achieve complete combustion. Using premixed combustion technology, power regulation range of 20% to 100%, i.e. when lowering the external demand, the boiler module can adjust itself to match the output demand and, module design, the module can start to meet the required load portion, it can be maintained at the same high efficiency low load operation. fully intelligent work, thermal efficiency of 92% on average, each module can be burned separately, a real energy saving. Flexible mounting, electrical automatic modular combination boilers, a single input power to be 240kW, up to 40kW, adjustable range of 20% to 100%, in a larger change in elastic and flexible to meet the heat requirement, even if a certain module failure, additional modules can also work, will not affect the heating requirements, reliability is very high. Variety of security devices, including the flame guard, ignition failure protection, smoke protection, overheating protection, pressure protection, etc. to ensure ease of use. Adaptability of small volume, a single area of ​​0.56 square meters, light weight electric boilers can be installed in a small space, convenient maintenance. Boiler module efficient and environmentally friendly exhaust temperatures than ordinary boiler flue gas temperature, heat loss harmful emissions to meet environmental requirements, low-noise combustion technology, the noise less than 50 decibels, and adjusting the air-fuel ratio does not affect the rest.

Put into use new multimedia exhibition is to create a precedent for technological gas boiler display, 360 ° holographic projection, fly screen interaction, interactive sliding screen, multi-radar means touch, smart models, the integration of virtual and reality, really appreciate rapid technology advancement in the field of party.

Environmentally friendly cost for electric boiler steam mill price for how much this government now demands that environmental protection is more and more strict. Many places began to phase out coal-fired boilers are, so these are beginning to use environmentally friendly electric or gas boiler steam boiler. For paper mills, most of the mills are using the gas, but still there are a lot of plants using steam power, so there is recent paper mill specific price consulting to fast boiler electric steam boiler. 1T current price of electric steam price of around 90,000, the paper mills use electric steam boiler 4t is to meet the production needs, the purchase of the paper mill electric steam boiler environmental cost of around 36 million.
