Combi Gas fired Steam Boiler Prices
The main structure of the internal combustion boiler detail: In the combustion boiler is a main flue of all, combustion residue after combustion of the fuel without directly heating the surface of the mixed working fluid is heated and the flue gas, together with steam as the working fluid work output of method of operation, high efficiency boilers. The internal combustion boiler thermal industry is part of the production of steam. Next to be described in detail the structure of the main combustion boiler: a boiler shell, the pressure receiving member is an important potshell shell type boiler, it is the role space for storing water and soda and steam are separated place. In shell type boiler, boiler shell placed combustion chamber (furnace) and the heating surface, the effect of which was underway boiler body. Potshell cylindrical container is made of welded steel sheet, we split it into three parts: the cylindrical portion is an intermediate portion, both ends of the tubesheet portion is simplified, and some people open end of the tube sheet hole. Simplified by the two or more tube sections butt weld made, the minimum length of the barrel section is not less than 300mm. When the boiler is greater than the inner diameter of the shell boiler 1000mm. Simplified access potshell wall thickness should be not less than 6mm, inner diameter of the shell when the pot is not more than 1000mm, simplified access to the boiler shell thickness is not less than 4mm. Both sides of the drum and the tube plate is connected to the boiler shell simplified, many small holes drilled in the tube plate, through the hole in the fire tube. Front tube plate further defines a larger hole furnace connected. There are many simple pan upper takeover, which takes over a main steam valve, safety valve, manometer, water gauge and the like. Pan with water separator housing interior, surface sewage, and the like into the water. 2, furnace, furnace boilers are specific shell type pressure element, inside a furnace combustion chamber, the outer coating from the boiler water. Furnace outside the furnace by the water pressure. Therefore, it is the worst working conditions the pressure element shell type boiler. Because the furnace by the high temperature flame burning, the temperature is higher than the temperature of the boiler shell, its thermal expansion problems particularly prominent in the boiler fuel, the oil combustion temperature is high, a high furnace thermal strength, severe temperature changes, there is required furnace good performance thermal expansion and contraction. General furnace are made waveform. And some shell type boiler or furnace to a flat circular flat circular shape Singapore. 3, fire tube, the main fire tube boiler heating surface of the boiler shell. Generally use is made of boiler steel φ51mm ~ φ102mm, the front and rear tube plate by welding or play mode coupled expanded joint, when Expansion, connecting the fire tube and inflation port after inflation tube plate using 90 ° pull side contact. Front and smoke at a relatively low temperature plate, inflation bell mouth pull side can be connected. When a welded connection, in order to ensure sufficient bonding strength, and the tube end is not overheating, the tube end projecting required length of the tube plate is not less than the wall thickness plus 1.5mm, but not in excess of the connecting seam 5mm. Imported oil-fired boiler, and some in the furnace exit, fire tube to tube sheet welding connection. But in other parts of the fire tube to tube plate with flange 90 connected to the expander. Effect is produced outside the smoke tube of the tube furnace heated by flue gas through the combustion water in the tube, in order to gradually generate steam, also called "squib." Generally have the following forms: a straight barrel, also called "light pipe", the advantage of a small light pipe smoke resistance, the disadvantage is fouling the inner pipe easily. Heat transfer effect is also poor. Light pipes are typically seamless steel tube, but also useful for welding boiler tube inlet. Another is a threaded tube, which is pressed inwardly out of a recess in the seamless pipe, it seems like a thread, so called "threaded pipe." The advantage is that the flue gas flow within the tube, changing the flow cross-sectional area, the flow velocity of flue gas is also changed and swirl effect. Therefore, it is better than the light of the heat transfer tube and hard fouling. The disadvantage is greater than the resistance through the light pipe has a certain velocity before the flue gas swirl effect more obvious. The third is to add steel wire or steel wire to the formula Fu light tube. It is a light pipe inside the tube into a tube-type inflammation oxidation resistance good steel wire, inside the flue gas flow at the fire tube, steel wire plays a role similar to the threaded tube. If you want to fire tube cleaning, can easily be removed steel wire, steel wire and light pipe are more convenient cleaning. This form of fire tube easy to manufacture, simple maintenance. In order to maintain the strength of the tube plate, according to strength calculation, be reinforced hole in a predetermined position region of the tube plate. Specific fire wall is thickened, with a thick-walled welded tube to tube plate, so that both as reinforcement, acting also as heating surface, the thick-walled tubes referred to as "bracing tube."
Whether gas combi fired steam boiler prices is a substitute for coal-fired boilers and a secondary air for gas steam boiler, which is a boiler, for all of us, it is also a knowledge and understanding, have a comprehensive understanding and understanding, in order to ensure learning products, at the same time, you can get yourself some new knowledge from it, rather than nothing at all, which in turn affects the learning process of the product. Function gas boiler the ignition system that ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Hot water boiler boiler assembly PC-style controller, all functions are stored on a smart chip, intelligent boiler, digitization, automation, humane, intelligent control of boiler water temperature, water temperature reached the heating automatically stop; large screen fonts display temperature, boiler water temperature at a glance. 1. What are the requirements for gas steam boiler manufacturers do? Gas-fired steam boiler this boiler, its production and manufacture of ordinary boilers companies, is not difficult. Therefore, as long as there is a boiler manufacturing qualification of Class C manufacturer or business, we can manufacture gas steam boiler. So, on this issue, the answer is yes. 2. Gas-fired steam boiler, which is a substitute for coal-fired boilers do? In addition, once the role and secondary air in the boiler what? An alternative gas steam boiler is a boiler fired boilers, and therefore may be used in place of coal-fired boilers, gas steam boiler may also be used. For this boiler, combustion plays a role of primary air, the wind plays a role in dragging fuel, secondary air plays a role in combustion. 3. Is there a demand for biomass fuel gas steam boiler?

What are the common type gas combi fired steam boiler prices have? Common types of gas steam boiler is as follows: fuel (gas) is oil or gas as fuel, burning the fuel using a burner to heat the gas as steam carrier. Structure is generally divided into two kinds of vertical, horizontal, mainly based on these two forms of device space height. Gas based on coal as fuel, gas and steam as a heat carrier. Hand generally divided into vertical burn, horizontal cylindrical type, three kinds of gas fired horizontal plane structure, mainly based on labor intensity stoker thereby form these three points. For electric heating electric heating oil furnace, heat is generated and transmitted by the electrical heating element is immersed in the gas and steam to steam gas medium by the circulation pump to force liquid recycle gas steam, with a heat transfer to or more heating equipment, heating equipment after unloading, re-circulation pump, back to the heater, and then absorb heat, heat transferred to the device, again and again, to achieve a continuous heat transfer the temperature of the heated object rises, the heating to achieve process requirements.
