The design, construction and superintendence of a wide variety of steam boilers, hot water boilers, and power plant boiler.
Small straw coal fired steam boilers will be fully modernized popular in the market after the 1980s, China's economy has undergone rapid changes in boiler industry is more prominent, national boiler manufacturing companies increased by nearly 1/2, small steam boilers will be fully prevalent in the modern market, and It can be formed independent development of generation after generation of new products. Small steam boiler is the era of economic development indispensable commodity, what the future will bring, but is well worth study. Group mainly used for small industrial R & D and production of small steam boiler, as far as we know, much higher production of small steam boiler manufacturers of small steam boiler prices, leading to small industrial input costs are also high, so many customers stay away, we had to continue small traditional steam boilers. Small steam boilers will be fully popular us on this cost, has been doing research experiments, and finally developed a small steam boilers for small industrial production process used at the beginning of 2017, we produced a small overall structure of the steam boiler Unlike other steam boilers in the modern market , through our special processing technology, the structure of the entire boiler changes, the use of safer, lower operating costs, more cost savings for small industry owners. Small steam boilers will be fully prevalent in the modern market, the Group's how we analyze the energy industry Riding out the following four points:? First, in terms of environmental protection, small steam boiler burning material is primarily natural gas, natural gas is a now clean energy, without waste combustion, the exhaust gases, as compared to coal, oil and other energy sources have a safe, high calorific value, clean and other advantages. Small steam boilers will be fully prevalent in the modern market two small steam boiler from a safety point of view is generally aspirated pipeline, the use of gas pressure units pre-tuned, fuel combustion more fully, the boiler is stable. Third, the thermal efficiency perspective, a small part of a steam boiler steam boiler pressure, since the connection within the furnace condensing system, the exhaust gas temperature is less than 110 deg.] C, operating thermal efficiency of 93%. Fourth, the use of the economic point of view, since the small water capacity of less than 30 liters steam boiler, from cold start to 5 minutes to produce saturated steam, warm-up time is greatly reduced, saving energy. Automatic intelligent operation, no fireman guard, eliminating salary expenses. Small steam boilers will be fully prevalent in the modern market is not difficult to see that the future prospects for the development of small steam boiler is very broad, because it is a vertical, small, small footprint, easy installation, small steam boiler to replace the traditional small excellent product steam boiler.
Learning materials heat boiler 1, the boiler is three safety accessories: water gauge, pressure gauge, safety valve. 2, the normal operation of the boiler water level is 0 ± 40mmH2O, the maximum does not exceed 0 ± 80mmH2O, the normal water pressure of 5.5MPa, to allow the fluctuation range of 4.5-6.0MPa, normal pressure boiler feed water temperature should be 105 degrees Celsius. 3, steam flow is not larger than the normal water boiler feedwater flow reasons, the measuring device instrument to do so. 4, the steam flow rate is less than the abnormal overheating damage reasons of water flow, water wall damage, damage to the economizer, the boiler is full of water, measuring device instrument to do so. 5, points on the furnace process CCP washed three times water gauge, pressures of 0.05-0.1MPa, 1.0MPa, 2.8MPa. 6, it is determined whether the normal water table and put into operation to see if the water level fluctuates slightly exemplar. 7, the boiler water pressure test and the test is divided into P overpressure test of two, when the water pressure P test, the boosting speed of not more than 0.35MPa 0.5MPa down rate does not exceed per minute. To the boiler water blowdown 8, the pressure in the boiler shutdown boiler water temperature drops below 80 degrees Celsius. 9, the position of each ordinary pressure test is hydrophobic doors: a door opening, the second door is closed. 10, the boiler-burner with a swirling-type and DC type two. 11, elemental analysis of coal with a composition: C, H, O, N, S, moisture, ash. 12, the main component of the blast furnace gas is: CO.'S time, nitrogen gas, blast furnace gas pressure is lower than 1500Pa, the user must reduce the amount of gas. Fire stop its pressure 1000Pa, working pressure 4000-8000Pa, the upper limit for the dangerous pressure 10000Pa, the lower limit is 2000Pa. 13, the main component of the coke oven gas: CO, nitrogen gas, coke oven gas pressure is lower than 1500Pa, must reduce the amount of gas, which pressure is 500Pa fire stop, working pressure 5000-7000Pa, the upper limit is 8000 Pa pressure the risk, the lower limit is 1500Pa . 14, the high, the main features of coke oven gas is flammable, explosive, toxic. 15, proximate analysis of coal with a volatile content, fixed carbon, ash and moisture. 16, boiler water circulation loop fault has stagnated, cycling back down the tube vaporization, soft drinks stratification. 17, the pulverized coal burning furnace radiation heat from a heat source of flame, high temperature flue gas convection heat. 18, the pulverized coal ignition and quick combustion conditions are sufficiently high temperature furnace, a sufficient amount of air mixed well, pulverized coal and air. Enough burn time. 19, ignition of pulverized coal into the combustion stage, the combustion stage, burning ember stage. 20, boiler mechanical rolling bearing does not exceed a predetermined temperature 80 degrees Celsius, the slide bearing does not exceed 40 degrees Celsius. 21, with factors affecting the steam load boiler water, boiler water salinity, pressure change, the vapor space of the drum height. 22, the principle of the steam separator drum gravity separation, inertial separation, centrifugal separation, separation of the water film. 23, the first ignition of the pulverized coal volatiles, fixed carbon is the latest ignition, the combustion of carbon is the longest. 24, steam soluble salt contaminated steam quality reasons, mechanical carryover. 25, the normal operation of the boiler drum water level in the glass tube than the water level high 50MM, when the water level in the steam table overall door leak, the water level high water table, the total gate leakage when the water level is low. 26, a method for enhancing heat transfer with a heat transfer coefficient is increased, raising the average temperature difference between the heat transfer, the heat transfer area is increased. 27, into the boiler furnace wall refractory layer, three-layer insulating layer and the sealing layer. 28, light blue flame blast furnace gas, as a bright golden yellow flame co-firing light yellow flame, coal, coke oven gas when the combustion gas as a combustion time. 29, the boiler by the "pot" and "furnace" composition, "pan" refers to a soft drink system is mainly composed of the drum, the downcomer, the header, waterwall, economizer, superheater composition; "oven" refers to a combustion system, a furnace, a burner, an air preheater composition. Calorific value 3.27GJ 30,1 tons of steam.
