industry gas fired combined water tube steam boiler
Water tube boiler for cocoa factory
A 15-ton oil and gas water tube boiler produced by ZG boiler provides steam for cocoa processing. The plant is located in Côte d'Ivoire and requires a steam boiler for production due to the expansion of production.
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.
When the pressure of the industry fired combined water tube steam boiler protection small small steam boiler pressure exceeds the rated boiler steam pressure protection, the need for chain protection: is shutdown, the system stops the combustion; fire mouth can also be varied, single-stage or two-stage combustion, You can adjust the amount of oil, so the buck, to ensure the safe operation of the boiler. Fuel (gas) pressure protection and steam boiler water, as the use of multiple protection: the pressure controller typically use two pressure controller, the pressure signal converted to an electrical signal, the electromechanical converter, the function of the high pressure, or low levels of signal The electrical switching loss, external circuits or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; pressure controller adjusts single fire or dual fire burning the actual operating pressure; for large burner, the pressure may be adjusted according to the size of the size of the amount of fuel, and always maintain a stable pressure relief valve operation is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design feature, the exhaust pressure relief, to ensure the normal operation of the boiler. Temperature protection temperature protection is an important procedure in the safe operation of the boiler, is particularly important for the regulation and protection of the boiler temperature steam; at the same time to regulate protective role in over-temperature hot water boilers. Conventional boiler temperature protection means is a bimetallic temperature controller.
Boiler precipitator technical principles of environmental protection and the development trend in recent years, the rapid development of gas power plant boiler in the direction of large-capacity, high-parameter, either manufacturing or operations management have been close to the advanced level. Boiler and gas industry to maintain large, widely distributed, high energy consumption, heavy pollution, energy efficiency and pollution control the overall level compared with foreign countries have a certain gap, a huge energy saving potential. By the end of 2012, China's use of gas in industrial boilers 467 000 units, with a total capacity of 1.78 million tons of steam, the annual consumption of about 700 million tons of coal, accounting for over 18% of the country's total coal consumption. China's gas lower overall energy efficiency of industrial boilers, about 15 percent of its actual operating efficiency lower than the international advanced level, with great potential for energy savings. In recent years the rapid development of technology the dust bag, in particular accessory bag filter (dust bag, dust bag cage pulse valve, control of the PLC technology, etc.) to improve quickly, while baghouse 10% desulfurization efficiency can be improved It is dry boiler flue gas desulfurization one of the major thermal power plant equipment. Boiler precipitator dust is the most effective pollution control equipment. It has a high dust removal efficiency, after the flue gas-containing filter baghouse dust concentrations below 50mg / m3, even at 10mg / m3 or less, and can efficiently remove the fine dust particles. Boiler boiler precipitator not just in the production of which use can also be used in other fields of thermal power. During use of the boiler generating the flue gas and dust is inevitable, the boiler boiler precipitator dust is separated out from the flue gas, thus reducing the dust pollution and facilitate further flue gas desulfurization, denitrification process. Spark arrestor smoke dust is mainly used in some high temperature and flue gas containing process Mars. For example, the flue gas cupola, intermediate frequency furnace flue gas, a furnace flue gas and so on. The main role is to eliminate smoke sparks, to avoid burning dust bag. Spark arrestor has a variety of structural forms, cyclone, louvered like. The most effective way of collecting cyclone is, the guide vanes guide the flue gas using a cyclone-type rotational flow, after the dust and large particles Mars cylindrical guide vane duct wall collision or off. When the smelting furnace flue gas containing spark large particles, dust bag will cause damage. Mars trap can effectively trap particles Mars in the flue gas, the protection of the bag filter. The entire device by the PLC control unit, automatic cleaning, discharging and automatic temperature control and over-temperature announcer.
