Details installed gas boiler combustion system that we need to pay attention when installing a gas boiler combustion system, inviting professional staff in advance of the circuit diagram design, so that when installing the status line installation will not appear unreasonable. Also, pay attention to install some fire-fighting equipment, which can provide protection for our security. Unit ventilation should generally remain the total combustion air amount at the rated load. Combustion process controller provides a separate set of contact start-stop control. May be formulated in a variety of burner start-stop loop cascade control relay 10A is a fuse, relay start-stop control stops the control terminal may be connected to the burner, may directly control the power of the burner. Both constant pressure sensor, water power, fuel, gas pressure set value is detected after the automatic controller opens. Time pressure sensor, water supply, oil, gas, and their detection circuit, alarm and found the problem immediately shutdown flame protection, the controller automatically displays the point of failure, an alarm sounds machine. Installation room oil, gas line gas boiler, boiler room should be strictly in accordance with design, specification, and should refer to the burner. Fuel system pressure test after installation is complete, should be 1.25 times the working pressure (minimum test pressure of not less than 0.4MPa). After the fuel pipe installation system should be flushed with water or steam flushing, flushing should have approved technical measures, the number of washing is not less than the secondary blowing, blow up until the clean medium, should be cleared after the purge debris and dead. After installation of fuel system should be oil circulation system-wide test. The gas should be the shortest route to the burner, the air supply pipe diameter must be larger than the constant value parts of the burner duct.
Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type boiler paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
Gas boiler heating surface elements and hydraulic machine hydraulic system temperature Xiao Bian told you about the gas boiler heating surface elements and hydraulic machine hydraulic system was increased 1: heat impact: low heat, low temperature combustion theory. To ensure that the design parameters and capacity of the boiler, fuel consumption and more, the furnace outlet increases eye pattern, a large amount of smoke, and the temperature and pressure so that the heat transfer gas velocity in each of the convection heating surface are increased, resulting in convection heating surface endothermic the amount of increase. Thus, each of the heating surface area of the boiler will be changed accordingly. 2: volatile Impact: coal fuel gas-fired boiler low volatile and is not easy to catch fire and burn, furnace volume heat intensity should get smaller, the larger the volume of the furnace. Flame length, the furnace should be higher. In order to ensure stable ignition of the fuel, the water wall surface of the burner arrangement Refractory laying tape, reduce heat absorption area waterwall combustor to maintain the high temperature, hot air and powder feeding hot air temperature higher, so relatively arranged much air preheater heating surface. In order to ensure the fuel burn, requires a larger excess air ratio, the combustion temperature in the furnace and reduce the amount of flue gas increases, it should be arranged to increase the convection heating surface. 3: Effect of Moisture: Water large, combustion temperature in the furnace is reduced, reducing the radiant heat absorption in the furnace, the flue gas increases the amount of heat absorption increases convection heating surface. Thus, convection heating surface required multi worth area. Meanwhile, moisture, high temperature hot air requirement, while the arrangement requires more air preheater heating surface. 4: Ash Impact: ash content, will aggravate the wear convection heating surface, in the design of the convection heating surface, should be used in low-speed cigarette or other friction reducing measures. Low ash melting point, should be used in a low heat furnace cross-sectional strength, thermal strength burner zone wall and the furnace volume heat intensity, to ensure that the back of the furnace and the convection heating surface not slagging. For low fuel boiler ash melting point, it should be employed in slagging combustion. For ash, it may also be employed multiple flue arrangement. 5: Multi sulfur, ash can cause corrosion and plugging of the low temperature heating surface, also cause high-temperature corrosion. Therefore, the design should pay attention to the selection and arrangement of the parameters of the heating surface, and take appropriate measures. As heating temperature, and contamination of the hydraulic system, but also an integrated form of the fault, the primary measured by measuring the oil temperature and a small amount of hydraulic components. Oil cooling during rotation around the start of operation to thermally. Temperature too high will produce the following faults: 1, temperature rise, the viscosity will decrease oil leakage increases, the overall system efficiency and volumetric efficiency of the pump is significantly reduced. Since the viscosity of the oil is reduced, thin film and other moving parts of the spool are cut and broken, the frictional resistance increases, resulting in increased wear, heat generation system, lead to higher temperature. 2, high oil temperature, mechanical thermal deformation, so that the gap between both the hydraulic components of different coefficients of thermal expansion becomes smaller moving member stuck, causing operation failure, they affect the precision of hydraulic equipment, resulting in variable quality parts processing difference.
Oven before the gas china water tube hot water boiler supplier should have conditions: ① boiler ended conduit means passing the fire test pressure. ② furnaces wall, holding full of things end, acceptance pass. ③ smoke duct means end, the end of incubation, the induced draft fan receiving apparatus failed commissioning. ④ oven cold working means necessary electrical instrumentation, calibration pass. ⑤ An delineated request being through the external cold mortar mix is bilateral shelved. ⑥ oven with wood, diesel oil, coal and all kinds of things (including review, site lighting, etc.) Preparatory end. ⑦ Ovens way to fully rely on the device, and has nothing to do and the way to take Ovens full withdrawal, liquidation garden shabby. ⑧ Ovens staff trained qualified
