electric boiler for school

The common types of boilers are as follows: fuel (gas) is fuel or gas as fuel, using burners to burn fuel, as a heat carrier. Generally divided into vertical, horizontal two structural forms, mainly according to the equipment space height of these two forms. Coal combustion is coal as a fuel, as a heat carrier. Generally divided into vertical hand-fired horizontal cylinder type horizontal machine burning three types of coal-fired structure mainly according to the labor intensity of coal so as to divide these three forms. For an electric heating oil furnace, heat is generated and transmitted by the immersed electric heating element. As a medium, the circulation pump is used to force the liquid phase circulation, and the heat is transferred to the oil furnace. Using one or more heat-using equipment, after unloading with the heat-using equipment, re-passing through the circulation pump, returning to the heater, re-absorbing heat, and passing it to the heat-using equipment, so that the continuous transfer of heat can be realized and the temperature of the heated object will be raised. Meet the process requirements of heating.

In mid-March this year, Shenyang City, the first boiler industry issued emission permits. Plan will livestock poultry, dairy products manufacturing, automobile manufacturing and other industries 29 issued emission permits, issued by the maturity shall not sewage, sewage behavior of errant card companies to investigate and punish. This is also the industry's first Shenyang boiler emission permits.

According to the State Department "to control emissions permit system implementation plan" and the Ministry of Environment "discharge permit management approach", 2017 in Shenyang City has completed thermal power, paper, cement, electroplating, pharmaceutical, pesticide, textile printing and dyeing industry, 54 enterprises license issuance of work. 2018, the city completed the issuance of emission permits 128, including iron and steel industry 5, slaughtering and meat processing industry 106, 16 water treatment industry, ceramic industry one, according to industry certification and time-bound national requirements, so that " should be sent to do hair. "

This year, Shenyang City, according to "stationary sources of pollution permits Classification Catalog" requirement, will be livestock poultry, dairy products, Condiments fermentation products manufacturing, food manufacturing other convenience food, wine manufacturing, footwear, plywood manufacturing, bamboo and rattan wood furniture manufacturing, polyvinyl chloride, phosphate fertilizer, automobile manufacturing, battery manufacturing, non-metallic waste and scrap metal processing, garbage to hazardous waste sludge as fuel for thermal power generation, sewage treatment and recycling, environmental control industry , heat production and supply, electroplating facilities, sewage centralized treatment of industrial waste water and other 29 industries issuance of emission permits. Up to now, has been launched boilers, water treatment, ceramics, automobile manufacturing, battery manufacturing, phosphate fertilizer industry and electroplating processes work permits issued.

Shenyang Ecological Environment Agency, responsible person, emission permits to take "a card-style" management, so that all the laws and regulations of the environmental requirements of an enterprise integration to a convergence of the proposed permit up to implement the main responsibility for polluters. A company issuing a discharge permit, enterprises through the establishment of self-commitment, self-monitoring, accounting records and regular reporting system has proven its emissions by law, to further strengthen fine management.

Shenyang in the discharge permit issued during the EIA procedure will be incomplete, excessive emissions, there is the issue of corporate environmental management ordered rectification to achieve "issued an industry, to clean up an industry, an industry specification, an industry discharge standards." In the future, Shenyang will be implemented in accordance with the regulatory card issuing companies to carry out law enforcement inspection post card, after intensive license management, enterprise undocumented sewage discharge permits and do not follow the behavior will be investigated according to law.

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.

Beijing 500 square meters of heating area, for example, in rural and urban areas to enjoy the "coal to electricity" subsidies. Electric boiler heating season runs from 21:00 to 6:00 the next morning, a total of 10 hours, after residents per kilowatt subsidy policy only costs 0.1 yuan. Under full load state has only 9 dollars. The remaining time is basically not reach full capacity, we count three hours working at full capacity, 10KW for 500 meters, 150 kilowatt-peak electricity price 0.3 yuan / kWh, 45 yuan, a total of 500 square meters per day 10 + 45 = 55 yuan , a heating season at 120 days per total 6600 yuan. If the user can press staff to guide behavior to use electric boiler for schools, power consumption will save about one-third.
