gas fired hot water boilers for heating

Operation of the boiler, including what? Including the operation of the boiler, what does? Following on from the Henan fast boiler company to tell you about: 1. The water level regulation of normal water level in the middle of the gauge (1) of the boiler. Operation with the magnitude of the load is adjusted: to maintain a high level during low load, high load to maintain a low level. Changes should not be down more than 40 mm. (2) to be run on the water level gauge to compare the two groups, if the water level display should be corrected promptly identify the cause. (3) To achieve a balanced continuous boiler feed water, ground water supply, water supply less, to maintain the water level in the normal water level fluctuates slightly in the vicinity. (4) load change is large, prone to false level. Pay attention to judgment, in order to avoid misuse. 2. Steam pressure regulator (1) when the boiler must constantly monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. (2) increasing the boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. (3) boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and to adjust the amount of water. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes. 3. Combustion adjustment (1) combustion index. Normal combustion boiler comprises a uniform supply of the fuel, reasonable ventilation, adjusting three basic aspects combustion. B. maintain a 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. C. fuel ash to reduce ash content in the combustibles to be below 10%. d. reducing the temperature of the exhaust gas boiler exhaust gas temperature should be controlled below 200 ℃. e. excess air negative pressure holding furnace boiler 1.2-1.4, by adjusting the balance of the blowers to maintain the furnace pressure is 2-3mm. F. to improve the thermal efficiency of the boiler thermal efficiency of the boiler should be kept above 60%. (2) adjusting the combustion a. Reasonable amount and the distribution of fuel to the amount of air needed for combustion. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. b wind principle feature: 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. c is the normal combustion conditions: fuel ignition start at 300mm from the shutter of coal, even flames, the fire bed formation, at the end away from the combustion grate at the end of 300-500mm. d. Hold appropriate furnace temperature to avoid coking. E. fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. F. less than 30 minutes residence time of the fuel on the grate. Our company provides services related to the installation of the boiler!

In the near future, at home and abroad more than hazardous chemicals, major accidents have occurred, causing casualties and property losses. Is a profound lesson, Henan Energy Regulatory Office will co-Provincial Development and Reform Commission issued the "Notice on alternative transformation of the province's coal-fired power business major hazard (liquid ammonia tank)" and actively promote the province's power industry ammonia tank alternative transformation.

"National Development and Reform Commission and the National Energy Board to implement the views on the promotion of electricity reform and development of the field of safety of" clearly "to strengthen the major hazards source control, there are significant hazards during the production of coal-fired power generation enterprises should study the implementation of major hazards alternative rehabilitation programs. " Henan Province TV as fire, liquid ammonia tank safety risk management and control situation is grim. To actively implement the "opinions" requirements, Henan Energy Regulatory Office investigation and carefully combing the province's power industry the basic situation of major hazards, and actively carry out reconstruction work research initiative to communicate the situation with the Office of the Provincial Development and Reform Commission, the provincial emergency management, efforts to promote reconstruction work as soon as possible. "Notice" requirement province of the power generation enterprises should further enhance political stance, overcome difficulties, vigorously promote the major hazard (liquid ammonia tank) and Improvement, under the premise to ensure safe production, the province's coal-fired generating units and strive to 2020 in liquid ammonia tank renovation completed before the end of December. New coal-fired power generation projects should all use the technical route no major hazard.

Next, Henan Energy Regulatory Office will replace liquid ammonia around the transformation as an important safety regulation. For failure to complete the transformation of liquid ammonia replacement power companies, to be included in the list of key regulatory target, for there are significant risks or accidents in accordance with regulations to be strictly punished according to law, and urge enterprises to strictly implement the main responsibility to effectively prevent accidents, efforts to increase intrinsic safety level of the enterprise.

How to avoid the chemical processing enterprises boiler boiler water pollution chemical processing companies how to avoid water pollution? It is well known in the food production process, many sectors need to use boilers, such as cooking, faced with the problem of sewage treatment, also with a certain level sterilization, dry, wine and so on. In the country's growing emphasis on environmental protection, continue to increase supervision of enterprises under the enterprise adoption of what approach to avoiding disadvantages, complete sustainable development? Primary, flue gas collection equipment processing equipment. Since SMEs by financial constraints, skills, and other places, a time can not be cut all the transformation, it is possible, after passing through the coal-fired boiler exhaust gas purifying exhaust purification device tail device, such as a fume hood, an exhaust gas collection processing device, effectively to prevent the direct discharge of black smoke, a serious impact on the surrounding environment. Second, clean power conversion, such as coal gas, coal to electricity. I learned that a beer factory invested more than 10 million will replace all coal-fired boilers, gas-fired. Now, 180 tons of steam boiler plant now farewell all coal, burning a low nitrogen gas cleaning switch, effectively reduce pollution. And compared with previous coal-fired boilers, coal saving more than 80,000 tons per year business. Again, the original boiler for energy saving, skills promotion. Programming with the furnace arch, adjust the secondary air to optimize the planning aspects of the planning grate, uniformity of air distribution, so that plenty of fuel burned, burning power progress. It is understood, Shanxi, a business research and development of environmentally friendly gas-solid two-fired boiler using low-grade nitrogen incineration furnace desulfurization, flue gas purification tail, the whole active control and other skills to complete energy efficient, which means that the stop, auto-run and clean intent emissions. Eventually, equipment sewage treatment facilities. Many food processing plants because of waste water, untreated sewage discharge and perhaps willful discharge, was ordered rectification probably ordered the closure of news after another. Because food processing wastewater organics, heavy metals, a high concentration of suspended solids, wanton discharge highly contaminated water, soil and living environment. All in all, China's boiler industry, neither sunrise industry, not a sunset industry, food processing industry but indispensable industry. However, along with constantly promote the national energy saving policy, whether it is food processing enterprises, is still food machinery manufacturing enterprises, must always assume social responsibility, uphold the concept of energy saving, reduction may reduce pollutant emissions.
