Steam Gas Gas Desulfurization to achieve excellent results steam oven gas steam oven must sample tests, the thermal conductivity was measured quality of appearance, flash point, viscosity, acid, water, and carbon residue, provided with heat transfer fluids plant proof mass It is consistent with the book, but also provide the basis for future changes in the operation of medium quality monitoring. Means passing the tests of the gas-steam heat transfer fluids using pumps to transfer fluids within the furnace and the injection of hot expander. When pumps heat transfer fluid to the injection system, should check again the furnace, heating equipment, piping system drain valve, drain valve is closed, in order to avoid loss of heat transfer fluids. While the exhaust pipe and the valve opening on the furnace one by one, to exclude air, until a closed gas steam flows. It stops when the oil level gauge appears on the expander injection heat transfer fluids, and then start the circulation pump, for circulating cold. Existing gas steam oven dry dust, do not meet wet desulphurization process of flue gas CWS humidity, water vapor in the flue gas as coal-water slurry up to 36%, some as high as 40% or more water content of coal-water slurry, If we consider only the dust and sulfur dioxide that is not enough. Arts gas 5t steam boilerboiler supplier company after multi-party experts to study, test, develop a dusting product, the successful use of coal-water slurry plenty of water in the flue gas as a carrier, by cooling, reducing condensation, dust and sulfur dioxide capture down, to achieve excellent results gas desulfurization steam oven. The effect of dust reaching the user's satisfaction. Gas welding gas steam oven must be operated by welders holding boiler and pressure vessel certification of welders. Welding dimensions meet the design drawings and process documents, bead height is not less than the base material, the base material with a smooth transition. Gas fuel gas steam oven weld and heat affected zone no cracks, holes, craters and slag. Weld undercut hole deeper than 0.5mm, the total length (the sum of both) is not more than 1/4 of the circumference of the tube, and not more than 40mm. Construction of gas steam oven strict compliance with welding procedures and other relevant standards and regulations, and make construction records welded to record the record.
Pressure fire operations and precautions Henan fast boiler's 5t steam boilerboiler supplier Xiao Bian told you about the operation of steam boilers and pressure fire precautions and stainless steel high temperature magnetic pump structural characteristics 1. pressure steam boiler fire steps of (1) to reduce boiler load, according to the length of time of shutdown, the seam thicker, the thickness is generally not more than 200 mm, suitable to accelerate the speed of the grate. (2) to the slag is thickened seam about 1 mm from the stop grate rotation, the drum is stopped, the operation of the induced draft fan, blowing off a small segment of the regulating plate stopper and dampers qs, relying on natural ventilation to maintain coal the lean-burn, the sewage, boiler water level will rise to the maximum allowable level. If the fire burn coal gate, grate can be switched on again, the coal-fired back, a distance. (3) the recovery boiler needs to run, as long as the opening lead, a blower, to adjust the smoke, and the wind baffle plenum segment adjusting the opening degree of the shutter, the adjustment of combustion steam boiler seam thickness to be normal, start grate, can be restored run. 2. Note the use of a steam boiler (1) before starting Check power supply voltage, there are unusual circumstances water, close the drain valve opens the water supply valve, check whether the pump stuck, stuck if the pump, remove the fan cover, rotation of the motor shaft to the flexible state to boot. (2) When the steam boiler maintenance or replacement of parts, turn off the power to avoid live work dangerous. (3) electronic control box, pump motors and other parts should avoid damp water to prevent burning boiler should pay attention to keep clean. (4) steam boilers in accordance with quality requirements, when using the apparatus sure to install a water softener, the water softener is not used because the boiler may cause fouling, may cause serious squib, shortening the life of the boiler. (5) Please note that when using sewage. And at least once a day with a discharge pressure of between 0.1MPa to 0.15MPa discharge may be prevented clogging of pipes, sewage should be properly connected, to guard against burns. Stainless steel high temperature magnetic pump structural features: a sliding bearing magnetic pump sliding bearing materials impregnated graphite, PTFE and engineering ceramics. Because of engineering ceramics has good heat resistance, corrosion resistance, abrasion performance, so the sliding bearing magnetic pump more use of engineering ceramics production. Because of engineering ceramics are brittle and expansion coefficient, so the bearing clearance is not too small, so as not to hold the shaft accident. Since the magnetic pump in order to lubricate sliding bearing medium conveyed, it should be used depending on the medium and conditions, making use of different materials bearing. 2. Cooling lubricating fluid flow control pump operation must be flush cooling internal friction annulus region between the sliding bearing and the magnetic rotor and the containment shell with a small amount of liquid. Coolant flow rate is typically 2-3% of the design flow of the pump, the annulus area between the inner magnetic rotor of the eddy current generated spacer bush high heat. When enough cooling lubricant or flushing holes poor, clogging, the medium will result in a temperature above the operating temperature of the permanent magnet, the inner magnetic rotor gradually loses its magnetism, the magnetic force actuator failure. When the medium is water or water-based liquid, the temperature rise can be maintained in the annulus region of 3-5 deg.] C; or when the medium is a hydrocarbon oil, allows the annulus region of the temperature was maintained at 5-8 ℃. Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!
Cause of the high energy consumption of electric 5t steam boilerboiler suppliers through a lot of practice and testing, has made great progress in terms of a unified understanding of the design and practice getting closer and closer. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Currently, electric steam boiler heating operation and management, divided into two categories: professional management and unit housing construction sector management itself, the management level is generally low. Professional management in good condition, a few self-management units at a high level, in the most basic high energy consumption, low efficiency of state. In addition, widespread attention heating social benefits, but energy-saving consciousness, the application of new technology, new achievements of small, long-term stay on the extensive experience of management, not to the level of refinement of scientific management. For a long time, in the development plan, the electric heating steam boiler, a new, integrated planning joint planning of lack of awareness. Residential construction and use of all available space, scattered along the road of small hot water boiler room has become a matter of convenience. Form a compact electric steam boiler steam boiler and a small capacity electric power consumption is large electric steam boiler birth defects. Forming two small facts, and indeed closely related to the lack of unified planning, but also because of lack of planning and hard to avoid blindness. In the past for a long period of time, various safety considerations due to the heating of the design, the design heat load calculation results generally much larger than the actual required value. Therefore, the emergence of the world's more than a radiator, electric steam boilers, large pumps, large diameter of the situation, the mainframe carriage pull carts situation in the world, the phenomenon of low load, the flow is widespread. This is because the designers of the factors affecting the heating of insufficient knowledge, poor operations management such as heating, furnace workers low level of technology. They worry that heating is not hot enough, dare reduce the thermal load, resulting in equipment is still too large, creating a vicious cycle.Free Chat
