Economical and energy-saving: the new generation of biomass pellet fuel can save 30% - 60% of the operating cost compared with oil, gas and electric heating boilers. Convenient installation: this series of generators do not need to be inspected, and the tedious annual approval procedure can be avoided. Shandong Fully automatic steam generator At the same time, the machine is assembled for modules, and professional installation procedures are not required. High efficiency operation: adopt the design of multiple flue gas backflow, optimize oxygen enrichment for many times, cooperate with professional dust removal and energy saving equipment, the thermal efficiency reaches more than 90%, and can continuously produce steam. Low carbon and environmental protection: Through reasonable design, biomass fuel is semi gasified and burned, and smokeless combustion is achieved. Reliable security: It is equipped with pressure, water shortage, security valve and other protection devices to ensure stable operation and reliable security of the boiler. vertical Fully automatic steam generator factory Simple operation: microcomputer intelligent one button operation, automatic feeding, automatic ignition, cycle start stop and fault alarm functions are used for simple operation. The labor intensity is greatly reduced, and the use of the boiler is more humanized. Convenient maintenance: the overall structure of the boiler is reasonable, and the installation is convenient. There is a cleaning port under each furnace. The main components have inspection ports for future maintenance and repair.

After the cold furnace of oil fired and gas fired boiler is ignited, the speed of temperature rise shall be controlled at 10 ℃/hour, mainly because the viscosity of oil temperature is large when it is cold, and the flow rate in the heating surface pipe of the whole equipment is relatively low. Shandong Fully automatic steam generator The oil film on the pipe wall is thick, so the heat transfer condition is poor when in use. If the heating speed of oil and gas fired boiler is too fast during use, it is easy to make the local oil film temperature too high. The equipment is in the stage of driving away the residual moisture and moisture contained in the heat conduction fluid in the system within the temperature range. vertical Fully automatic steam generator factory In oil and gas fired boiler, when the steam exhaust volume at the vent pipe of the expander is relatively large, there will be water hammer at the bottom of the equipment. In this way, the vibration of the pipeline will accelerate, and when the swing amplitude of the pressure gauge pointer in each part of the equipment is large, the temperature rise will be stopped and the constant temperature state will be maintained.

Most people may already know something about flue gas waste heat recovery, because they have already explained a lot about it. In order to let you know the relevant knowledge of flue gas waste heat recovery, the following is a brief introduction to the two methods commonly used for recovery. Shandong Fully automatic steam generator Two methods are usually adopted for flue gas waste heat recovery: one is to preheat the workpiece; The other is to preheat air for combustion support. The flue gas preheating workpiece needs to occupy a large volume for heat exchange, which is often limited by the operation site (this method cannot be used for furnaces that are used intermittently). vertical Fully automatic steam generator factory Preheating air for combustion support is a good method. It is generally configured on the heating furnace, which can also strengthen combustion, speed up the temperature rise of the furnace, and improve the thermal performance of the furnace. This can not only meet the requirements of the process, but also achieve significant comprehensive energy-saving effect.

Oil gas boilers have obvious characteristics. The main fuel is oil or gas. According to their functions, they can be divided into steam boilers and hot water boilers. Most of them are designed with large furnaces, with thermal efficiency of more than 98%. At the same time, they also have the characteristics of fully automatic and safe operation. Shandong Fully automatic steam generator Generally speaking, oil and gas boilers adopt excellent boiler body design. WNS horizontal boiler adopts wet back three return structure, which can reduce the exhaust gas temperature and make the boiler thermal efficiency reach more than 90%. Therefore, the combustion efficiency is relatively high, greatly extending its service life. vertical Fully automatic steam generator factory In addition, in the design of oil and gas boiler, there are often hinged front and rear smoke boxes. The maintenance method is simple. Most of them are insulated with light aluminum silicate fiber to reduce heat loss. The external use of all stainless steel plate skin improves the appearance quality. In addition, the oil and gas boiler is equipped with an excellent combustion machine, which greatly improves its stability. The combustion machine has an automatic purging function, It can also prevent deflagration during ignition.
