Steam order steam water tube boiler heating in winter north of the advantages and disadvantages of our country, cold weather, heating is essential, often used before coal-fired boilers for heating, but coal-fired boilers to serious air pollution, now gradually replaced by steam boilers. Steam boiler is also very common type of heating equipment, are now gradually penetrate to the south. Steam boiler heating both advantages and disadvantages, we compare: first, an analysis of the advantages of using pulverized coal combustion boiler, the coal is in fact relatively high temperature, the surface temperature of the steam boiler is relatively rapidly increased, but in fact, this system can withstand particularly low cooling system. 2, the steam in the evaporation process, as in fact it is the gas density is quite small, for which the net pressure steam boiler itself is relatively small. 3, the steam itself does not require any external pressure resistance of the propulsion system for it. 4, steam boiler has a clear advantage, the heating effect and very fast, but it stopped gas speed is faster, especially for users of intermittent heating. Second, an analysis disadvantage, during use in a steam boiler, because the pipe is relatively high stability, and is not easy to heat, in the course of prolonged use, the dust around the surface of the device, so that the relatively poor surroundings, and heat slowly dispersed, easy to burn people. 2, in a more simple production conditions, the use of the boiler does not care, and the system will cause leakage particularly large heat loss, so that the waste of energy is relatively more serious. The disadvantage of steam boilers we could have been avoided, in use of the process will be seriously careful to avoid being burned or wasted energy.
Inside the Fangkuai order steam water tube boiler plant, there is a special corrugated furnace bladder production line, which can be processed according to the computer setting mode. At the same time, this is also a unique processing technology of Fangkuai Boiler. The cost of natural gas fuel alone exceeds 5 million yuan per year. The corrugated furnace liner fired by this production line can not only increase the heating surface of the boiler, but also alleviate the damage caused by the thermal expansion and contraction to the combustion chamber, and greatly extend the service life of the boiler.
Gas-fired steam boilers are a very wide range of special equipment, usually built in boiler rooms. However, in the process of loading and installation, some problems must be paid attention to, otherwise it may cause a certain degree of economic loss.
1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.
2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.
3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.
4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.
Gas, the working principle of a steam order steam water tube boiler gas heating device (burner) to release heat, radiation heat transfer is first absorbed by the water wall, the Wall Boiling water, a lot of steam into the drum for generating steam separator (DC out furnace), separated the steam entering the superheater full, by radiation, convection method and continuous top horizontal flue furnace absorption, the flue gases heat the back pass, and the superheated steam temperature reached the requested work. Power generation boilers are generally provided with a reheater, steam is used to heat the work of the high-pressure cylinder, the reheater go out of the reheat steam, the low pressure cylinder continuously to generate power. Plain speaking, a steam boiler the burning of the fuel absorbs heat energy must be water parameter (such as pressure, temperature, etc.) of the steam device. Boilers and boiler furnace divided into two parts, the pot is filled with water to the metal container, the fuel is burning furnace section heat absorb water pot furnace and burning the fuel to steam, with the basic principles of almost boiling water, the pot equivalent kettle, oven stove equivalent. Horizontal gas steam boiler Schematic heating apparatus (burner releases heat, radiation is first absorbed by the water wall heat transfer, vaporization of water boiling water wall, a lot of steam into the drum for generating steam separator (DC out furnace), separated full steam enters the superheater, by radiation, convection method and continuous top horizontal flue furnace absorption, the flue gases heat the back pass, and the superheated steam temperature reached the requested work. power generating boilers are generally provided with a reheater, is used to heat the steam by the high pressure acting cylinder, and reheated steam reheater go out, the low-pressure cylinder continuously to generate power. plain speaking, a steam boiler the burning of the fuel absorbs heat energy must be water parameters ( the apparatus steam pressure, temperature, etc.) of the boiler and the boiler furnace is divided into two parts, the pot is filled with water to the metal container, the fuel is burning furnace section heat absorb water pot furnace burning fuel converted steam, boil water with the basic principle is similar to the equivalent of pot kettle, oven stove equivalent. vertical gas steam boiler principle diagram vertical gas steam boiler Furnace is an energy conversion device, the input energy to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, the boiler through the conversion of thermal energy must be externally output with steam, hot water or organic heat . used for power plant, boats, locomotives and mining enterprises. the main rationale original working passed to a boiler water in the container after use of the thermal energy released or the fuel burned in the industrial production of heat, the temperature of the water reaches the demanded or must steam pressure thermal equipment boiler in the "pot" and "furnace" two somewhat performed in conjunction with the water into the boiler in the future, the heat in the soda system boiler heating surface will absorb transferred to the water, the water heated to a bound of temperature and pressure generating hot water or steam, is drawn applied. in some incineration equipment, continued burning of the fuel heat release, high temperature flue gas occurs by thermal incineration of communication, transferring heat to the boiler heating surface, the temperature was gradually lowered itself, and finally discharged from the chimney classification steam boiler: a, divided by the fuel: 1, gas boiler, 2, oil-fired boiler, 3, gas boiler, 4, electric heating boilers, 5, atomic energy boiler, 6, waste heat boiler, etc., during the first four at most, the most common, the lowest operating costs of gas-fired boilers, but large area, environment pollution, the operator requested more; fuel gas boiler high degree of automation, operation cost is higher than gas, smaller footprint, fewer requests operator; electric heating boiler I have not had the operation, but the operation cost should be the highest, but a small boiler area, environmental best; other boiler is not introduced because they do not understand Second, by mode of heat transfer into the fuel gas-fired boiler is usually fire tube boiler water tube boiler, fire tube boilers, water, fire tube boilers and other. typical model: WNS series (horizontal burning boiler combustion chamber), the characteristics of such boilers: simple structure, an additional amount of evaporation is generally small (typically ten tons or less, there are also large, but usually do not exceed 35 tons), Kai boosting faster furnace, boiler water is relatively low request; gas boiler are usually water-tube boiler, water tube boiler high thermal efficiency, but messy configuration, the boiler high quality requested. Third, by additional pressure into the low-pressure boilers, pressure boiler, high pressure boiler Fourth, the use is divided into days boilers, industrial boilers, power generation, marine boilers.
