The main difference between the fuel gas boiler thermal control of the basic requirements of fuel gas boiler room in claim 1. The thermal control of the basic fuel gas boiler fuel gas boiler main features of the gas boiler grate firing combustion system is different in that, mainly in the nature of the fuel and combustion different. Fuel gas boiler combustion system has the following two characteristics: 1) If not properly controlled combustion process, the furnace can form a large number of combustible gas mixture, when mixed gas deflagration, the furnace may cause an explosion, causing heavy casualties and property losses. 2 combustion) of fuel gas boiler combustion space, the combustion speed, load responsive. 2. controlled boiler fuel gas and fuel gas requirements of the boiler combustion system adapted to, the following basic requirements for the fuel gas boiler automatic control system: (1) reliable system configured to prevent fuel gas boiler explosion, the design of the fuel gas boiler when automatic control system must be designed to give priority to the reliability of a system, the detection system may employ protective control system provided separately, if necessary. In the selection of microcomputer control system, it is necessary to adopt a dual configuration instructions manual and the necessary back-up of important parameters such as measures to improve the reliability of the control and protection systems. (2) starting the program control strict fuel gas boiler shutdown should process control, rigorous testing of the fuel during the start-stop system, air supply system and a flame monitoring system, since a failure to avoid the shutdown process. (3) timely protection should be reported depending on the circumstances, the choice of the following associated with the combustion system alarm and interlock protection projects: 1) drum level limit alarm and interlock protection. 2) Overpressure drum (temperature of hot water for boiler overtemperature) alarm and interlock protection. 3) flameout interlock protection. 4) Low oil pressure interlock protection (oil-fired boiler). 5) high oil temperature interlock protection (oil-fired boiler). 6) low oil temperature interlock protection (oil-fired boiler). 7) Low gas pressure interlock protection (gas boiler) 8) Interlock high gas pressure (gas boiler). 9) wind down interlock protection. 10) Burner flange interlock limit switch. 11) combustible gas leak alarm. 12) earthquake interlock protection. (4) a fast system response when running the fuel gas boiler abnormal combustion flame is off, the automatic control system required to be quickly cut off the fuel supply, to prevent the fuel into the furnace, thus requiring automatic control system fast enough response speed. (5) When the load adjustment linkage fuel gas boiler load changes, fuel regulator response speed faster than the response speed of the air supply system. When the load suddenly increases, the rate of increase of fuel greater than the corresponding rate of increase in the amount of air, resulting in incomplete combustion, soot is produced; when the load is reduced suddenly, fuel reduced speed, resulting in high oxygen smoke. For small boiler-off control of combustion increase or decrease should match the amount of increase or decrease in the wind, or it may cause flameout. Thus in the design of automatic control system, should be considered synchronized adjustment of combustion air. (6) field instrumentation for explosion-proof gas boiler automation systems, field instrumentation should be used in explosion-proof instrument.
Around the city to promote the coal to gas project, the major institutions of the heating system put forward higher requirements. Central Conservatory of Music is available to students and teachers clean, safe, comfortable, energy-efficient heating environment, protect the health of teachers and students, to transform the traditional boiler treatment. Praise fast boiler Willie sharp series obtained in the transformation of low nitrogen boiler major institutions in Beijing, the Central Conservatory of Music in late 2017 with the signing of fast boiler boiler purchase contract, ordered six Willy sharp series V6-99, to for the entire school's heating facilities.
Features china hot water boiler prices description: hot water boilers currently on the market are mainly classified according to different fuels, which are divided into electric water boiler, gas hot water boiler, hot water boiler fuel oil and coal-fired hot water boilers. Fuel (gas) hot water boiler diesel or natural gas as fuel, the water is heated by a burner, to provide heating and to achieve life, bath with hot water, a high degree of intelligence boiler, heating speed, low noise, no dust. Today small introduction pressure hot water boiler composed of four characteristics;
What type steam boiler is? Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Press working medium can be divided into natural circulation boiler, forced circulation boiler, boiler DC. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass china hot water boiler prices, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. 2, according to the water-tube boiler flue gas flow, boiler shell (fire tube boiler), water - Combined fire tube boiler. 3. Press installation fast loading boiler, boiler assembly, bulk boilers. 4. Place the vertical and horizontal boiler boiler according to the boiler drum. 5. End-use domestic boilers, industrial boilers, utility boilers, marine boilers and motor. 6. Press media steam boilers, hot water boilers, soda boilers, organic heat carrier boiler. Natural circulation water circulation, forced circulation and once-through boiler, combined cycle. 8. atmospheric pressure boilers, low boilers, medium pressure, high pressure boiler, high pressure boiler. 9, the internal combustion boiler combustion, external combustion boilers. 10, coal-fired boilers, oil-fired boiler, gas-fired boiler, pulverized coal boiler, waste heat boiler, electric heating boilers, biomass boilers. Many types of steam boilers, the key is what kind of needs, because different categories, so in different places, use different steam boiler. In order to ensure better use.
