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.

Code of Fire Protection for Oil-fired boilers

Oil-fired boilers are more convenient than traditional boilers in environmental protection, but their fire protection system is indispensable because of the particularity of oil, and its fire protection is mainly as follows:

1. There should be a reliable anti-static and safe grounding device in oil tank area and discharge pipeline, and the grounding resistance value (less than 0.5 ohms) should be tested regularly. 2. It is forbidden to store combustible materials in oil area and temporary buildings which are easy to catch fire should be dismantled in time. 3, it is prohibited to do welding work in the running or off-standby state of the oil pipeline. When welding must be carried out on an oil pipeline, before welding, the oil pipe that needs to be welded must be disconnected from the oil system in operation or standstill status (such as removing the welded oil pipeline or home plug) and then flushing the pipeline, Ensure that its interior is oil-free, oil and gas to prevent welding operations are oil and gas deflagration . 4. When open fire operation in oil area, must handle fire work ticket, and should be reliable safety measures. 5. We must strictly implement the oil zone management system. The foam fire fighting system and fire extinguishing equipment of the oil system of the oil fired boiler must be inspected and tested regularly according to the regulations. 7. Hose for fuel system should be periodically checked for replacement. To prevent fuel leakage due to hose aging. If oil leakage is found in insulation material during maintenance, oil leakage point should be eliminated and heat preservation material should be replaced. 9. Monitor the oil temperature of the oil tank. If the oil temperature exceeds 50 ℃, the spray water should be put into the oil tank. That's all the fuel. Boiler fire code, I hope everyone for their own safety please strictly abide by.(119) Preparedness of fuel-fired boilers before ignition

Future development of gas steam boiler is now, due to air quality and the environment has been severely damaged, the Chinese government and relevant departments of this proposed reform, especially in the last few years, we continue to strengthen and urban renewal efforts of management awareness of urban governance continue to increase, there are many heavily polluting factories were forced to shut down or go to the countryside, where coal-fired boiler of this pollution is more serious. Therefore, coal-fired boilers will soon face the fate of being eliminated, but instead is environmentally friendly gas steam boiler. In many areas of the construction of coal-fired boilers, relatively speaking earlier, use of time is relatively long, the use of effects and economic aspects have not reach people's needs, the cost of coal-fired boiler is relatively high, and after use will produce waste water, waste, emissions of harmful substances, so that the use of coal-fired boilers will cause serious pollution to the air. From an environmental aspect is concerned, it will be the first coal-fired boilers will be eliminated. In contrast there would be "waste" gas boiler, it belongs to an eco-friendly boiler. Economically speaking, the general use of more than 5 years of small and medium sized coal-fired grunt no longer have the value of the burned gas, thermal efficiency is relatively low, while the gas boiler coal-fired boiler best alternative. Although the oil-fired boiler thermal efficiency is relatively high, but the smoke pollution in the atmosphere is far greater than the gas-fired boiler, oil-fired boiler and there are also issues related to oil transportation and storage, it lost the advantage of long-term development. Gas boilers have very obvious advantages compared with them. Further, the configuration does not require gas boiler soot blowers, ancillary equipment dust, slag and a fuel drying apparatus or the like, can save the boiler investment. In terms of maintenance, gas boiler is also a very big advantage, a simple gas boiler combustion system equipment, so the group. Maintenance is relatively small, there is a gas boiler slag deposit and high and low temperature heating surface corrosion does not exist, do not need to change the hot fittings and elements of the air preheater surfaces. No matter from which side, gas boilers are the best substitute to replace coal-fired boiler equipment, so the future development of certain gas boiler is much larger than the development of other boilers, gas boilers will set a new record in the future development .

Meanwhile, at the annual meeting of the excellent performance of employees also distributed millet television and different incentives such as bonuses, is intended to encourage employees to continue their efforts to create more success in 2019. In the meeting, the president has placed us deep hopes in 2019 to focus the project, focus on value, cohesion output!
