gas poles and timber cfb boiler in tanzania
Such as the use of coal fired poles and timber cfb boiler in tanzanias, coal heating value 5500Kcal / Kg (in terms of standard coal) around, (coal prices have continued their upward trend in the market price of 460 yuan per ton, and the purchase and sale channel is not smooth, to control the current energy under rotten mining waste and serious situation, the price of coal have continued upward momentum). 10t steam boiler steam coal consumption per ton of 0.2 ton, the price of 92 yuan. The hot gas is 8000kcal / Nm3, the price of natural gas per cubic 2.0 million, according to gas consumption per ton of steam gas consumption 80Nm3, the price of 160 dollars.
6 tons adjusting a combustion gas steam poles and timber cfb boiler in tanzania, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.
The arches of DHL Series Corner Tube Chain Grate Boiler can be redesigned according to the specification of the coal.
Reasonable requirements with the wind, it will cause the boiler coking. The ratio between each segment for the amount of wind, we need to determine good or bad based on coal quality, coal seam thickness on the grate, flue gas oxygen content, CO content, load size and other factors. For different loads and different combustion air in case of need to be summarized based on the ratio of long practical experience, the formation of a set of data in order to guide the operator to ensure the safety of energy-saving boiler operation.
Around at 6:00 on November 22, Guang'an City, Sichuan Province Economic Development Zone Industrial Zone, a company Newbridge burst distillation kettle explosion, the roof 20 square meters of workshop collapse occurred, had not resulted in a fire, but there are four people were injured, It has been transferred to hospital for treatment.
Suddenly the accident, the specific reasons unknown, Guang'an City, the municipal government attaches great importance to the explosion, immediately launched an emergency contingency plans, multi-power Guangan Economic Development Zone, safety supervision, environmental supervision, public security and fire protection, first time to scene to carry out rescue and subsequent disposal.
Distillation pot is directed chemical production still pot used in this step, also has a greater risk of leakage and fire accident-prone equipment. In recent years, leaking reactor, distillation kettle and other equipment, fire, explosion accidents occur frequently, mainly because often kettle equipped with a toxic, harmful hazardous chemicals, the accident consequences more serious than the general explosion, either to persons or property caused serious irreversible effects.
Distillation is one essential step in many process industries such as chemical industry, brewing, paper, food processing, it will involve the distillation process. Steam boiler equipment for the needs of enterprises to provide a distillation excellent choice. Steam boiler steam output, after a series of treatment steps of cooling, purification, extraction, etc., provides excellent quality of distilled water, for the production needs.
Fang fast has a very rich experience in R & D, manufacturing and sales of natural gas steam boilers, since practitioners, R & D and innovation has always insisted on clean fuels. One condensing gas steam boiler, gas steam boiler water, ultra-low nitrogen gas steam boiler ...... date, more than 200 kinds of types of boilers.
Over-temperature protection, over voltage protection, abnormal power protection, scale online monitoring, frost protection, the water level is too high, too low to protect and increase water protection than the traditional four fifth protection mechanism, so a series of protective measures, all-round to ensure the safety and reliability of operation of steam boilers, select the users of our products is very much at ease, peace of mind.
