China made brown coal hot water boiler
Fangkuai Company has a fully-automatic PLC intelligent control system designed and developed by itself with complete intellectual property rights. It adopts a combination of mechatronic control equipment and a programmable logic controller (PLC). Take the advanced programmable logic controller (PLC) as the "central processing unit" of the control system. The control system is operated through the touch screen, which greatly improves the degree of automatic control and operation reliability of the boiler, and the operation is simpler and more intuitive.
75 ton coal-fired circulating fluidized bed power station boiler
CBM provided a 75-ton coal-fired cfb boiler for power generation in a chemical plant in China. This boiler uses circulating fluidized bed combustion technology. The boiler steam pressure is 3.82 MPa, the steam temperature is 450 °C, and the boiler feed water temperature is 105 °C. Our circulating fluidized bed power station boiler has strong fuel adaptability and can burn anthracite, lignite, bituminous coal, lean coal and various biomass fuels.
Today, the principle of steam boiler and the construction of steam boiler 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 body is the lower part of the drum, the water-cooled pipe and the Pyrotechnic pipe The combustion part is composed of a chain grate and a drive device, and a combustion chamber composed of a boiler rack on the grate frame. 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 not only discharges smoke, but also It is necessary for the negative pressure operation of the boiler. 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. Steam boilers are force vessels and safety devices are necessary. All steam boilers can work better only in accordance with the correct operating methods.
10tph WNS fire tube boiler project for new energy industrySteam, as a kind of energy, is widely used in all walks of life. Longzheng Environmental Protection Technologies Co., LTD. is a new high-tech enterprise applying a number of energy-saving technology including biomass molding pellet combustion technology, water coal slurry combustion technology and natural gas combustion technology to provide pure steam for food, pharmaceutical, textile and other industries. Therefore, a steam boiler acts as the heart for the enterprise; it is important for the production line that the steam boiler runs stably for a long time. The "Green Revolution" has become a global trend recently; Longzheng Environmental Protection Technologies Co., LTD. takes an active part in environmental protection, the companies decided to obsolete previous boilers with excessive emissions and introduce several sets of natural gas fired steam boilers. ZOZEN, one of the most influential boiler manufacturers in Asia, customized a comprehensive boiler solution for Longzheng Environmental Protection Technologies Co., LTD.: ZOZEN recommended 4 sets of 10 tph WNS series gas-fired steam boilers for the company based on their actual demands for steam. This series of boiler adopts a large-diameter corrugated furnace to increase furnace heat transfer area, ensuring the stable running of the boilers. In addition, the boiler is equipped with a low NOx burner to reduce the NOx emission to 30mg/Nm3; furthermore, ZOZEN also installed economizer and condenser on the tail of the gas-fired boiler, which will effectively reduce the exhaust gas temperature below 60℃ and improve thermal efficiency up to 98%.
