Process describes extinguishing gas steam boiler 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 chinese standard 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.

Why chinese standard hot water boiler heating more energy efficient, more environmentally friendly: generally used for heating hot water boilers, but the need to use less steam production process. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. 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. Because it is more energy efficient than steam boiler, more environmentally friendly. First of all, in terms of fuel consumption, hot water heating than the steam boiler heating savings of 20% to 40% of fuel, this amount is very impressive. Summed up for two reasons: First, it does not condensate and heat loss due to evaporation of the secondary, two hot water heating pipe is heated by the use of special materials, as thin as possible to meet pipeline needs, heat loss is small. Heat loss due to the steam heating pipe caused by steam leakage large.

We have long known that fast boiler this brand, high-tech enterprises in Henan Province, the most influential brand, technology entrepreneurs contribution to enterprise and many other honors, so that our brand is very interested in each other fast. Through this collaboration, proving once again that our decision is not wrong, 15 tons of steam condensing gas boiler provides steam to fully meet the needs of our dairy products processing plant. --customer feedback

The heat loss of exhaust smoke is the largest of all kinds of heat loss in boiler. Generally, the heat loss of exhaust smoke is 6% of the heat fed into the furnace, and the heat loss of exhaust gas increases 0.5% when the temperature of exhaust gas increases by 12 ℃ and 15 ℃. So the exhaust temperature is one of the most important indicators of boiler operation. The following are several possible causes of increased flue gas temperature in the furnace: (1) slagging and ash accumulation on the heated surface. No matter it is the slag accumulation in the water-cooled wall of the furnace, or the ash deposition in the superheater, convection tube bundle, economizer and preheater, the thermal resistance of the flue gas measurement will increase, the cooling effect of the flue gas will become worse due to the deterioration of the heat transfer, and the exhaust temperature will rise. (2) excess air coefficient Big. Under normal conditions, the exhaust temperature increases with the increase of excess air coefficient at furnace outlet. After the increase of excess air coefficient, although the amount of smoke increased, the rate of smoke increased, and the convection heat increased, the increase of heat transfer was not as much as that of the increase of flue gas. It can be understood that after the increase of smoke speed, the flue gas leaves the heating surface without time to transfer heat to the working fluid. (3) the air leakage coefficient is too large. The flue gas leakage in the furnace and rear shaft of a negative pressure boiler is inevitable and the leakage coefficient allowed by a certain heating surface is specified. When the air leakage coefficient increases, the effect on the exhaust temperature is similar to that of the superheated air coefficient. And the air leaks away. The closer the furnace is, the greater the influence on the rise in exhaust temperature. (4) Water supply temperature. When the steam turbine load is too low or the high pressure heater is out of line, the feed water temperature of the boiler will be lowered. Generally speaking, if the fuel quantity is kept constant, the heat transfer temperature difference of the economizer decreases and the heat absorption of the economizer decreases when the feed water temperature is increased, which makes the exhaust temperature increase. (5) moisture in the fuel. The increase of moisture in the fuel increases the amount of smoke, thus increasing the exhaust temperature. (6) Boiler load. Although the boiler load increases proportionally, the amount of smoke, the amount of steam, the amount of water supplied, and the volume of air increase proportionally, however, the flue gas temperature at the furnace outlet increases proportionally. Increase, so that the exhaust temperature increased. After increasing the load, the outlet temperature of the furnace increases, the heat transfer temperature difference of the convection heating surface increases and the heat absorption increases. Therefore, the more the convection heating surface is, the less the influence of the boiler load on the exhaust gas temperature is. (7) fuel varieties. When the low calorific value gas is fired, the radiative heat transfer in the furnace decreases due to the decrease of furnace temperature, and the non-combustible components in low calorific value gas, mainly N _ 2, CO _ 2 and H _ 2O, increase the amount of flue gas, so the exhaust temperature increases. Although the excess air coefficient of furnace outlet is lower than that of coal burning, the ash content in the fuel oil is very low after the pulverized coal furnace is changed to burn oil, although the excess air coefficient at the furnace outlet is lower when burning oil. There is no larger ash particle in flue gas, and there is no cleaning effect of larger ash particle on the heating surface, and the convection heating surface is polluted more seriously. Therefore, combustion is not good, often smoke-emitting boiler smoke temperature rise. When there is a steel ball dust removal device at the tail, the exhaust temperature is slightly lower than that of burning coal because the tail is cleaner. (8) the operation mode of pulverizing system. For a closed pulverizing system with a silo, when the pulverizing system is in operation, as a part of the water in the fuel enters the furnace, the furnace temperature decreases and the flue gas increases, and the cold air leaking into the pulverizing system enters the furnace as a primary air during the operation of the pulverizing system. Reduction of air flow through air preheater To raise the exhaust temperature. On the contrary, when the pulverizing system is shut down, the exhaust temperature decreases.
