It can only be prevented by adding medicine to the pot. Tianjin Fuel oil steam generator Adding drugs to the boiler can further soften the water quality, making up that the softening water equipment cannot replace silicon, sulfur and heavy metal ions and anions, so that impurities such as suspended solids, water slag and scale in dissolved water have good looseness and fluidity, and then the impurities are discharged by sewage, thus preventing scale. The water treatment method is carried out in the pot, so it is called water treatment method in the pot. small-scale Fuel oil steam generator manufactor Therefore, boiler water treatment actually includes water treatment of feed water and quantitative feeding treatment in the boiler. Water treatment should only be carried out without adding drugs. The boiler water index basically does not meet the specified requirements, and the boiler cannot operate under good water quality. This is also the main reason for the softened water device. The softened water is also qualified, and the boiler will also be polluted.

High heat exchange efficiency. The fusion rate at the contact is more than 95%, the contact thermal resistance is small, and the thermal conductivity is good. Low flow resistance. Tianjin Fuel oil steam generator Since H-shaped finned tubes are similar to square structures, after being assembled into heat exchangers, the tubes are divided into many small channels by fins, which has a certain uniform effect on the air flow. The air flow is similar to longitudinal downstream flow, and the air flow resistance is relatively small. However, spiral finned tubes have strong air flow disturbance, high turbulence, and large air flow resistance due to the directivity of the fins. Less ash. The flue gas contains fly ash, which is easy to deposit on the windward side and leeward side of the pipe bundle. The H-shaped fin tube bundle has the characteristics of uniform flow and downstream flow, so it is not easy to cause serious local ash deposition, and the fly ash can be taken away with the air flow in time. Therefore, compared with spiral finned tube heat exchanger, H-type finned tube heat exchanger has less ash deposition. small-scale Fuel oil steam generator manufactor Small size and low weight. H-shaped finned tube has high area expansion rate, less ash deposition, and high heat transfer efficiency. When the heat transfer capacity is equal, the space occupied by the heat exchanger can be small. For reconstruction projects, the heat exchange area can be arranged as much as possible in the limited space to reduce the exhaust gas temperature, improve the waste heat recovery efficiency, or increase the maintenance space to facilitate maintenance.

The boiler adopts the combustion equipment suitable for the combustion of biomass fuel - reciprocating grate. In the structural design of the boiler, the furnace space of the boiler is larger than that of the traditional boiler, and the reasonable arrangement of the secondary air is conducive to the full combustion of a large amount of volatile matter released instantaneously during the combustion of biomass fuel. The boiler can be equipped with oil (gas) ignition burner to realize ignition automation. Tianjin Fuel oil steam generator The feeding, combustion, slag removal, water supply and ignition of the boiler can be automatically controlled, and the operation is convenient. The boiler is equipped with an automatic ash cleaning device, which can remove the ash on the heating surface of the boiler in time to ensure the efficient and stable operation of the boiler. The tail of the boiler is equipped with an economizer, or an air preheater according to the user's needs. Compared with the traditional boiler, the boiler has higher efficiency and lower exhaust gas temperature. High efficiency thermal insulation materials are used, the boiler surface temperature is low, and the heat dissipation loss can be ignored. small-scale Fuel oil steam generator manufactor All pressure parts are made of excellent boiler steel in strict accordance with Chinese national codes and standards. Each boiler shall be strictly inspected and tested before leaving the factory, including hydrostatic test and X-ray inspection. Manholes, inspection doors, fire observation holes, etc. are set to facilitate maintenance. The major characteristics of biomass boiler are: energy conservation, environmental protection, and easy installation and use.

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. Tianjin Fuel oil 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. small-scale Fuel oil steam generator manufactor 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.

The produced waste heat boiler for hazardous waste incineration is a natural circulation water tube boiler, which adopts a single drum vertical layout and a full membrane water wall structure. Tianjin Fuel oil steam generator The surrounding, top and three middle membrane water-cooled walls form a tight series of heat exchange flues. The convection heating surface is no longer arranged inside the heat exchange flue, and radiation heat exchange is adopted, so as to ensure the smooth flow of high-temperature flue gas containing strong coking adhesive ash in the heat exchange flue. Full automatic shock soot blower is arranged on the membrane water wall, and inspection holes and observation holes are reserved. small-scale Fuel oil steam generator manufactor The bottom of the boiler is composed of membrane water walls on both sides to form a water-cooled ash bucket, and the lower part is connected with a closed spiral ash extractor. The settled soot in the waste heat boiler and the ash removed by the soot blower are discharged out of the boiler by the ash extractor. The furnace wall is of pipe laying structure, and the outside is covered with corrugated steel plate.
