1 20t h automatic industrial boiler manufacture
Configuring steam 1 20t h automatic industrial boiler manufacture feedwater and steam boiler feed water equipment device points in claim 4 points: water supply system (1) of the steam boiler, should ensure safe and reliable water supply. (2) steam boiler should spare water supply equipment. Arrangement and number of units and capacity of backup water supply system of water supply equipment, should meet the following request: ① boiler steam boiler should be at most two vertical work to pump ** (one spare). ② Two capacity to pump, not less than 120% of the nominal overall operation of the boiler and the amounts of evaporation. ③ When the boiler room above three feed pump apparatus, which feed water total capacity should be: when the maximum capacity of a feed pump deactivation, the remaining capacity can always run parallel to the pump is not less than the rated boiler all running evaporated 120% of the sum of the amounts. (3) to the pump head (i.e., height of the water column required to overcome the static pressure of the respective dynamic pressure) should be greater than or equal to the algebraic sum of the following: ① water pressure drop difference water supply system (water column hydrostatic) and the water supply system. ② hot water boiler safety valve at the design pressure set pressure. ③ economizer system pressure drop drum. ④ The above three multiplied by the algebraic sum of the amount of 1.05-1.1 rich as appropriate.
July 26, 2016, Beijing, China Everbright Paper Co., Ltd. and the company signed a "split 6 tons of steam condensing gas steam 1 20t h automatic industrial boiler manufacture contract" by the company responsible for the WNS6-1.25-YQ split condensing gas boiler steam to all production, installation and commissioning work. The product is the use of condensing technology, effective emission of harmful substances SOx, NOx, COx, is industrial boilers efficient and environmentally friendly solutions.
One ton gas steam 1 20t h automatic industrial boiler manufacture to produce one ton of steam required number of cubic meters of natural gas First, we need to understand the need to absorb 1 ton of water into steam heat, and the heat released by combustion heat value of natural gas required by the boiler equipment, passed to medium water, the water absorbs heat changes in the physical properties of cold water into hot water and then gasified into steam, which will take it to absorb heat about 600,000 kcal natural gas quality. of course, the quality of the combustion engine is the most important, good product energy-saving gas boiler quality is a major factor raw gas steam boiler 1 t of steam per air consumption; heat value of natural gas per cubic 9000 kcal; thermal efficiency of the boiler 0.91; Job boiler can draw heat transfer index of 0.91x9000 = 8190, by 600,000 / 8190 = 73.000, i.e., each theoretically produce one ton of water vapor, gas consumes about 70-75 square.
Normal atmospheric gas hot water 1 20t h automatic industrial boiler manufacture combustion mode, which will result in excess air ratio in the mixed gas is too large, the flame temperature will produce thousands of degrees the boiler in operation, will form nitrogen and oxygen at elevated temperature conditions nitrogen oxides, the nitrogen oxide emissions are an important cause of air pollution.
