Commercial Hot Water Heavy Oil Boiler

Commercial Hot Water Heavy Oil Boiler

The fact that we determined to achieve cooperation with the fast boiler is a very wise decision, after a period of time put into the boiler efficiency significantly much higher than our original boiler efficiency, significantly reduce fuel costs, the economic benefits brought by the boiler is obvious. --customer feedback

How to select energy saving, gas-fired? We have to look at or listen to illustrate the introduction of natural gas boiler technician in the procurement of natural gas boilers. Gas-fired steam boiler, the type of gas commercial hot water boiler, gas conducting oil furnace, boiler different for different occasions. After determining the procurement of natural gas boiler models, need to understand the specific configuration of the boiler, configure the following criteria: 1, the main boiler is equipped with auxiliary equipment and what. 2, meters, valves and water boilers require careful examination to understand. 3, understand the control system of the boiler: boiler power electrical cabinets, power boiler control switchgear. 4, check the electrical control cabinet, console, the control system, the drive, a display, and other electrical equipment. 5, and riot unit boiler tank daily inspection. 6, boiler factory testing and commissioning. Clear cost price of natural gas boilers, installation cost of materials and installation of boiler worker costs, transportation costs and other parts.

Coal-fired boilers, fuel shots are fired, coal in the combustion chamber after the combustion heat release, the heating medium water or other organic heat (e.g., heat transfer oil, etc.) heated to a temperature (or pressure) of the thermal power plant. Coal is our energy use accounted for first, with a mature mining, transportation and sales channels, and the price is relatively low; but it also has many defects, low efficiency, resource utilization imbalance, burning emit large amounts of carbon dioxide and other harmful gases and dust, the larger impact on the environment pollution and high environmental costs.

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.
