WNS fire tube gas fired industrial steam boiler for sale
In the national standard of water quality standard, the water quality index of hot water boiler stipulates that the total hardness of water supply for chemical treatment outside furnace is less than 0.6 mmol / L. In recent years, in order to reduce the operating cost of heating units, some hot water gas-fired wns fire tube fired industrial steam boiler for sales have been overloaded due to the use of class Ⅲ bituminous coal as fuel instead of class Ⅱ bituminous coal designed to replace the designed type Ⅱ bituminous coal. During the maintenance in summer, it is found that the overloading boiler water wall tube fouling problem is more prominent, some boilers even occur tube burst accident. Why is heating hot water boiler overloaded, scale and even burst tube? Because the calorific value of class Ⅲ bituminous coal is higher, the type Ⅲ bituminous coal of the same weight is burned instead of the designed class Ⅱ bituminous coal. Bituminous coal increases the circulation of boiler riser is not absolute equilibrium, the geometric difference of riser and the heat load are different, so there is inevitably the deviation of flow rate between the risers. Due to the overloading operation of the boiler, some riser tubes are easy to overheat boiling because the flow rate is small, and the wall temperature is higher than the designed wall temperature, so that the scale and even the tube burst are easy to occur. How to prevent the boiler from scaling when overloaded? The heating hot water boiler operates under overload because of the scaling after the superheated boiling. Steam is produced in the process of superheated boiling. The water quality requirement of gas steam boiler is less than 0.03 mmol / L, which is much lower than that of hot water boiler. Water quality requirements. Based on the above reasons, the feed water hardness of heating hot water boiler is reduced, and the scaling phenomenon is eliminated by reducing 0.6mmol/L to 0.03mmol/L.
Process describes extinguishing gas wns fire tube fired industrial steam boiler for sale the fuel gas steam boiler characteristics of fossil fuels, biomass fuels extinguishing mechanism in the extinguishing process, the composition of the reaction products and quenching rate is also very different from the fossil fuels. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. 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. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. Extinction characteristic different from the fossil fuels of fossil fuels. Extinguishing process gas steam boiler biomass fuel is divided into two separate phases: volatile precipitation and extinguished, and a gas steam boiler and burn off the coke. The former account for about 10% of the time of the fire, which is about 90%. Specific extinguishing process as follows: After gas steam boiler fuel to the quenching chamber, heating the water and precipitated at high temperature thermal effect. Subsequently, the fuel gas steam boiler because the temperature continues to rise, from about 250 degrees Celsius, thermal synthesis starts, volatile precipitate and form coke. The volatiles were mixed and the temperature of air around the first gas steam boiler is ignited and extinguished. Under normal circumstances, the surrounding coke is volatilized gas steam boiler sub-extinguishing chamber oxygen is difficult to penetrate into the surface of the coke, as long as volatiles to dissipate the end, the temperature in and around the coke gas steam boiler has been very high, oxygen in the air may also be in contact with the exterior of the coke, coke gas steam boiler start off, it does produce ash when.
Foshan Gaoming Liu Ling Textile Dyeing and Finishing Co., Ltd. was founded in 2007, enterprises comprehensive strength, advanced processing equipment, detection means perfect, has a complete quality assurance system, the introduction into a large number of advanced production equipment, to ensure that technical standards and products stable to improve the quality of laid a solid foundation, enjoy a high reputation in the industry. Liu Ling Gao textile company twice with my company were to buy a 20 tons of steam and a whole 10 tons of steam condensing wns fire tube fired industrial steam boiler for sale fuel gas for the production of textile dyeing and finishing company. Fang fast with strong comprehensive strength and improve the service system to win the favor of the other side, communication from the initial to the final boiler factory-installed square fast all uphold the customer's perspective to think and observe the service concept, for the sake of clever Liu Ling textile companies according to the company's actual demand for textiles, the development of specific programs.
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.
