What type steam boiler type steam boiler of what we can from different angles on the boiler category:? 1, according to the working fluid can be divided into natural circulation boiler, forced circulation boilers, DC boiler. 2, according to the boiler flue gas flow tube, a shell boiler (fire tube boiler), combined fire tube boiler. 3, according to the installation package boilers, boiler assembly, bulk boilers. 4, according to the boiler drum placed vertical, horizontal boiler. 5, according to the purpose of life boilers, industrial boilers, utility boilers, boiler travel. 6. The medium steam boilers, 2000liter hot water boilers, soft drinks dual boiler, boiler organic heat carrier. 7. The water circulation natural circulation, forced circulation and once-through boiler, combined cycle. 8, the pressing force pressure boilers, low boilers, medium pressure, high pressure boiler, high pressure boiler. 9. The internal combustion boiler combustion, external combustion boilers. 10, according to the fuel fired boilers, oil-fired boiler, gas-fired boiler, pulverized coal boiler, waste heat boiler, electric heating boilers, biomass boilers. There are many types of steam boilers, the key is that you need which, because of the different classifications, so in different places, will be used to different steam boiler, so as to better ensure use. Working principle of a steam boiler heating device (burner) to release heat, radiation heat transfer is first absorbed by the water wall, the Wall Boiling water, a large amount of steam into the drum for water separation (excluding DC furnace), the separated saturated steam entering the superheater, and continues to absorb the top horizontal flue furnace by radiation, convection, heat of the flue gas flue of the tail, and the superheated steam to reach the required operating temperature. Power generation boilers are generally provided with a reheater, it is used to heat the steam through the high pressure cylinders acting reheater go out of the reheat steam, the low pressure cylinder to continue to generate power.
Six months from Hainan Sinochem Pharmaceuticals boiler equipment normally used in odd years, the equipment in good condition, our technical staff has repeatedly went to inspect the guidance.

Pressure boiler furnace designed to fully consider the characteristics of the fuel pressure boilers body member are two main drum and furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The overall structure of pressure boilers and boiler auxiliary equipment including two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler.
Daily maintenance of gas-fired boilerDuring operation, the gas-fired boiler should pay attention to the following points: (1) the gas-fired boiler does not allow positive pressure combustion or smoke injection in the furnace because it is easy to burn out the coal hole cover. (2) the bottom floor plane of the gas-fired boiler shall not be watered up in order to prevent damp corrosion. The gas-fired boiler shall be inspected every 2 weeks and every 3 months after the operation of the gas-fired boiler. (1) the gas-fired boiler shall be inspected and repaired in an all-round way after the operation of the gas-fired boiler every 3 months. (1) the gas-fired boiler shall be inspected inside and outside the boiler. If the pressed part of the weld, steel plate inside and outside corrosion phenomenon, if found in serious defects should be repaired in time, if the defects are not serious, the next time the furnace shut down repair, if found When suspicious, but does not affect the safety of production, records shall be made for future reference. (2) after inspection, boiler primer may be applied on the surface to prevent corrosion. 4. Gas-fired boilers and boiler base shall be painted at least once a year. 5, There are dry and wet methods for the maintenance of gas-fired boilers: dry method and wet method. Dry maintenance method should be adopted when the boiler is shut down for more than one month. (1) dry maintenance method: after boiler shut-down, the boiler can remove the water from the furnace, and the method of dry maintenance shall be adopted under one month. (1) dry maintenance method: after the boiler has shut down the furnace, Thoroughly remove the internal dirt, rinse clean, dry the furnace with a slight fire (be careful not to fire), and then apply a 10-30 mm diameter lump of quicklime. The plates are arranged and placed in the pan, without contact with the metal. The weight of quicklime is calculated at the volume of 8 kilograms per cubic metre of the drum, and then all manholes, hand-holes, pipe valves are closed and checked every three months. If the quicklime is broken, it needs to be replaced immediately. When the boiler is re-running, the quick lime and the tray shall be removed. (2) Wet maintenance method: after the boiler has stopped the furnace, the boiler shall discharge the furnace water, thoroughly remove the internal dirt, rinse it clean, and reinject the treated water until it is fully filled. Heat the furnace water to 100 ℃, let the gas from the water out of the furnace, and then close all the valves, where the climate is cold, do not adopt moisturizing method, so as to avoid the furnace water Icing damaged the boiler.
2019-8-10·the gas can bubble up thru the bottom of the tank, with the bubbles exchanging heat with the subcooled liquid. Finally, the gas can exchange heat directly with a condensing heat exchanger line at the cold head. For all three methods, the liquefaction rate must be measured. To increase efficiency of the liquefaction process, the gas may be preGet a Quote
