vertical cross tube fire tube boiler for food industry
When the hot water vertical cross tube fire tube boiler for food industry scale occurs, we first need to be analyzed scale category, and then determine the specific treatment. Boiler feed water before flowing into the boiler, to conduct water analysis and water softening process, until the water quality meet the national standard to enter the convection tube bundles. When the hot water boiler scale processing, general first pickling, water quality control and then take other cleaning measures. With cleaning measures to detect and replace the structure is seriously affecting the safe use of convection tube bundle. If scaling is particularly severe, only the replacement of the way, if a two pipes scaling serious, stuffy way pipe can be used. However, if a large area of the bundle are serious scale, the use of chemical cleaning more effective. Prior to chemical cleaning, mechanical cleaning may be employed before the loosening dirt, this cleaning effect will be better. For the scale silicates, more pickling effect. But the party fast hot water boiler experts also concluded a more important note: general dirt simple suggestion pickling, so lower costs. Mechanical descaling is generally less than 1 mm scale clean-up, if the amount of scale thickness to be selected in the above pickling.
V. Installation piping, valves, instruments and accessories
1, the instrument installation should be verified, be installed in the piping, valves, instrumentation drawings, energize the electric pump commissioning.
2, the safety valve should be installed after the hydrostatic test, the safety valve should be installed exhaust pipe, the exhaust pipe should be through the outdoor security. Exhaust pipe should be installed in the bottom of the drainage pipe connected to a place of safety. Valve shall be installed on the exhaust pipe and drainage pipe.
3, each of the sewage outfall should be connected to tank or other security, the pipe should be secured to prevent shifting or counter the occurrence of injuries blowdown.
4, the main pipe by the use of units other than the mating valve, the pipeline need to consider the thermal expansion, thermal insulation pipe wall should be.
5, the dial face pressure gauge should be correct, depending on the ease of reading and rinsing; draw red dial face, the boiler shown MAWP, rotating flexible plug should not be leaking, to smooth hydrophobic Table pipe insulation prohibited.
6, only for the manufacturer pipe valve instrument (within the range shown) or the like, the other parts of the users themselves straight pipe. If you have not ordered instrument valves, the factory produced only manufacturer to install non-national standard parts required.
Boiler plant equipment as three major important energy conversion device, fuel chemical energy into heat energy, and the pot was heated using thermal energy to become hot water having a sufficient quantity and a mass (steam temperature, steam pressure) steam turbine for use. The Anyang City, the power company to my company to buy a split 2 tons of steam condensing gas steam vertical cross tube fire tube boiler for food industry for supplying electricity demand. The WNS series split condensing boilers using advanced technology designed to greatly improve the thermal efficiency of the boiler, up to about 96%.
Paper mill with a gas steam vertical cross tube fire tube boiler for food industry models are generally the size of a paper mill started at least 30 million tons hundred ten thousand tons have bigger production, a large-scale paper-making enterprises demand for gas steam boilers have higher requirements, to ensure continuous continue to provide steam to be able to guarantee the paper mill demand for steam. Acting steam mill drying is play the role of heat or heating the raw material in the cooking process, resulting in significant dependence on the steam. Bid farewell to coal-fired boilers, and we'll see what gas steam boiler for paper mills use. 1, SZS6-1.25 / 194/104-Q, this is a saturated steam generated by the boiler 2, SZS6-1.25 / 350/104-Q, this superheated steam generated by the boiler is a steam boiler needs mill in accordance with aspects factors, the sales staff will use in the process of steam enterprises to assess and give recommendations.
