How much gas steam boiler

You know how the boiler works? Boiler parameters is a main boiler performance indicators, including the boiler capacity, steam pressure, steam temperature, water temperature and the like. Boiler capacity available rated maximum continuous evaporation or evaporation is represented. Rated evaporation under a predetermined outlet pressure, temperature and efficiency, the amount of steam per unit time of continuous production. Maximum continuous evaporation under a predetermined outlet pressure, temperature, per unit time the maximum continuous amount of steam produced. Steam pressure and temperature parameters including how much steam boiler, generally refers to a superheater, superheated steam pressure and temperature at the outlet of the reheater and superheater if no reheater, saturated steam pressure and temperature at the outlet of the boiler refers. Refers to a water temperature of the economizer inlet temperature, inlet temperature refers drum without economizer. Boilers can be categorized in different ways. Boiler use can be divided industrial boilers, utility boilers, marine boilers and boiler locomotive; by the boiler outlet pressure can be divided into low, medium, high pressure, high pressure, sub-critical pressure, the supercritical pressure boiler; boiler and by water flue gas flow path can be divided into the fire tube boilers, fire tube boilers and water-tube boilers, fire tube boilers and wherein the fire tube boiler and collectively shell boiler; press cycle can be divided into natural circulation boiler, auxiliary boiler cycle (i.e., forced-circulation boilers), and the combined circulation boiler once-through boiler; by combustion, the boiler chamber into the burner, and boiling Stoker furnace. Water vapor system, feedwater heated to a temperature in the heater, the water supply pipe into the economizer, after further heating into the drum, along with the mixing pot of water down to the water wall downcomer inlet header. Radiative heat absorbing soda water formed by the mixture in the riser in the drum reaches the waterwall tubes, the water from the steam separator means, steam separation. The separated saturated steam from the superheater to the upper stream drum, continue to become superheated steam endothermic certain temperature (most of the current 300MW, 600MW unit main steam temperature is about 540 ℃), and then sent to the turbine. In terms of combustion and flue gas system, the air blower into the air preheater is heated to a certain temperature. It is ground to certain fineness in the mill coal, a portion of the hot air from the air preheater carried into the furnace through a burner. Discharging pulverized coal burner and combustion air mixture is mixed with the rest of the hot air in the furnace and release large amount of heat. The hot flue gas flowing through the furnace sequence after combustion, Slag bundle, the superheater, economizer and air preheater, and then through the dust removal device, wherein the fly ash is removed, and finally sent to the chimney by the induced draft fan to the atmosphere.

Hot water boiler which is not equipped with no impact can cause demineralizer 1, the waste fuel boiler fouling occurs, resulting in poor heat transfer performance of heating surface, so that heat generated by the combustion of the fuel can not be timely delivered to the boiler water, but a large amount of heat is smoke away, resulting in exhaust gas temperature is too high, if the exhaust gas loss increases the thermal efficiency of the boiler will be reduced. In order to maintain the nominal parameters of the boiler, fuel must be increased, thereby wasting fuel. About 1 millimeter scale waste fuel ten percent. 2, the heat receiving surface is damaged due to deterioration of the heat transfer performance, fuel combustion heat is not quickly transmitted to the boiler water, resulting in the furnace and the flue gas temperature. Thus, the temperature difference on both sides of the heating surface increases, the metal wall temperature, a decrease in strength. Under pressure pot, bags and even blasting will occur. 3. Reduce heat boiler output due to the deterioration of the performance of boilers, need to consume more fuel to reach the nominal rate of evaporation. However, with the increase in the scale thickness, the volume of the furnace becomes large, the fuel consumption is limited. Therefore, it is possible to reduce the output of the boiler. 4, the corrosion damage to the metal: oxygen in the water, acid, base materials will corrode the metal surface of the boiler, it is thinned, recess or perforation, thus reducing the power of the boiler, seriously affect the safe operation of the boiler. 5, in addition to improper operation Priming outside, when the boiler water contains more sodium chloride, sodium phosphate, and silicides oil, boiling or evaporation process boiler water, boiler water occurs when soap and organic base when Teng because soda will produce compost. Foam liquid surface, formed soda pool. No softening, easily scalable. Due to the continuous evaporation steam, boiler of calcium, magnesium, high impurity concentration is 30-50 times that of natural water, fouling rate beyond our imagination, only six months to a year, from 1-2 mm.

Gas steam thermal cracking reaction furnace gas steam oven should be carefully introduced reflect in the use, to guard against water, acid, alkali and leakage into the low boilers using the system, the system should be installed filters installed to prevent debris into various types, to ensure the purity of the oil . Gas and steam is easily oxidized during heating, the acid value of the oil is increased at high temperatures and a large change rate. Steam oven gas kinematic viscosity gradually increases, which is due to the thermal cracking gas vapor component at high temperature, thermal polycondensation reaction. Thermal cracking reaction resulting in generation of small molecule compounds, to reduce its viscosity; oxidation temperature when the inner conduit thermally cleavage occurs at 300 ~ 400 ℃, coke formation in the pipe, the inner wall of the device, leading to heat accumulation pipe affect the heat transfer efficiency, sludge poor flowability, transfer oil accelerated aging failure, but also to the furnace, pipes local overheating, impairing the mechanical strength of the threat to personal safety.

As the "Star Pavilion" on the show, the arrival of fast boiler is attracted quite a stir. Guests and friends from all over the world friends are gathered in front of "fast Boiler" booth, feeling the charm to bring clean boiler. This is the third appearance in the fast side of the trade show, our booth set up in the middle of the field, in the light against the background, beautiful booth set off for the scene of different merchants brought extraordinary appeal.
