China steam electric boiler
Automatic water level control? Electric steam boiler can be set manually or pot Free subject: 108KW the water volume is less than 30.4, flexible and convenient: used in line JB / 2379-93 and "metal tubular electric heating element technical conditions" desired low heat load surface heating element; quality thick stainless steel tube outer heating wire, Ni-Ge alloy built expensive electric components, high thermal efficiency, and longer life. Garland using each heating element is connected to the control system employs multiple heating pipes packet control group can be set to manual or automatic mode; opening pressure can according to the flexible electrical power and steam consumption! 5, safety: in strict accordance with the whole "Steam Boiler Safety Technology Supervision" manufacture, possess a number of complete protection, leakage protection, water protection, ground fault protection, overpressure protection, steam, boiler automatic protection? 1, ease of operation: automatic intelligent control, without staff on duty. Can be set to manual or automatic mode; pressure, automatic level control, boiler fittings touch of a button, either into the automatic operation, the automatic control of the pressure controller, the control system can give food factory in three full pump load change two 10T gas boiler, electric heating automatic start-stop control! 2, clean environment: heating using electric energy, without any environmental pollution clean, easy to install small footprint! , Automatic level control? Electric steam boiler 6, the original electric stepper control, speed control can be divided according to the actual amount of steam, the boiler to reduce the impact on the power grid, so that the boiler operation is more stable.
Steam boiler is too many forms, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler is the lower part of the drum, water-cooled pipe and pyrotechnic pipe. The combustion part consists of a chain grate and a drive device, Add the boiler frame on the grate of the composition of the combustion chamber composition. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan is not only the exhaust gas, but also necessary for the negative pressure operation of the boiler. Steam boiler is pressure capacity Device, safety device is necessary. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment.
In recent years, the increasing popularity of Yichun City, Jiangxi Province comprehensive energy saving coal-fired boiler upgrade project, plans to eliminate 75% of the downtown 10 steam tons / hour and below the coal-fired boilers, a ban on new 20 tons of steam / hour and less fuel coal boilers; the rest of principle, then the new 10 steam tons / hour of coal-fired boilers.
Following this, Jiangxi Province Department of Finance issued a special subsidy fund boilers, Yichun downtown 2015--2016 phase-out 10 steam tons / hour coal-fired boilers companies grant. The subsidy standard is: 2 out of steam tons / hour and coal-fired boilers, subsidies to 10,000 yuan / Taiwan; out of steam 2-10 t / h coal-fired boiler, subsidies for 20,000 yuan / Taiwan.
Preparation (1) of the electric steam boiler before use, the operator must understand how this boiler, location, performance and working methods of the various accessories. (2), check the oil combustion, and each nozzle connection, power supply and the burner, the pump, the boiler installation accessory. (3), a clear main steam valve open, after closing the normal close it. (4), water level gauge inspection, confirmation flexible water level, normal position. (5), the pressure regulator is properly tuned, regulate combustion damper.
