In recent years, Siyang County town chrysanthemum industry as part of the ecological projects to enrich the people in the choice of chrysanthemum drying equipment, the county Environmental Protection Agency proposed to replace coal-fired boilers to electric boilers idea. Part chrysanthemum growers is objected that the idea costly and cumbersome, but after analysis and explanation of the Environmental Protection Agency and the power company personnel, electrical boilers have a deeper understanding of the use of electric boiler can not only improve drying chrysanthemum chrysanthemum quality and product phase, it did clean, safe, and there are various government subsidies, while coal boiler if the government out of the use, post-investment costs will be higher. At present, the boiler "electricity for coal" action has been noticed.

In recent years, Siyang County uphold the "gold and silver mines that lies to" development concept, vigorously implement alternative energy projects, alternative energy gradually extended to grain drying, drying fruits and vegetables, herbal drying and bathroom, hotels, restaurants, businesses and other industries. Siyang county party secretary said: "Winning 'Battle of Blue Sky', shouting slogans alone are not shouting to the sky, or from the 'coal to electricity,' 'oil to electricity' these specific things to start, through the implementation of alternative energy engineering, elimination of high energy consumption, low-energy-efficient equipment, the progressive realization of ecological priority, green development goals. "

Since 2016, the county completed a total alternative energy companies, service unit 686, phase out coal boiler 1336 units, to complete alternative energy electricity 256.69 million kwh. Energy saving alternative to business spending, reduce production costs and improve their efficiency and realize a production of "zero emissions" to protect the party clear water and blue sky. In mid-November, Siyang County was selected as "the second batch of national ecological demonstration counties civilization."

On a more specific type of a gas boiler chain grate coal steam boiler steam boiler and comparison of gas steam boiler and steam boiler, the following will be involved, for this specific kind of gas steam boiler furnace. Moreover, since it has a wide range of applications, and is the product website and keywords, so it is necessary to conduct in-depth and comprehensive understanding, so as to not miss any of its knowledge, and at the same time, but also allows the product to have good results, let us benefit from it. 1. Gas steam boiler and steam boilers, whether they comparable? Gas steam boiler and steam boilers, which are two specific types of boilers, however, from a professional point of view, these are two completely different boilers, although all in the boiler in this category. Therefore, gas steam boiler and steam boilers are not comparable, not suitable for comparison, because then no significance and value comparison. 2. The high-temperature gas-steam steam oven gas used, what to choose should be based on? High-temperature gas-steam oven gas and steam is used, it should be selected based on grades and hot gas-steam process requirements, and that should be the right choice for a variety of high-temperature gas-steam grades and strictly comply with the requirements "organic heat carrier furnace technology to monitor the safety regulations" this standard in order to achieve the proper use of gas steam. 3. gas steam heater and gas steam boiler, Is there a difference? Gas steam heater and gas steam boiler, although the two are similar in name photogenic, however, are two different things. Because, gas steam heater is a resistance heating gas with steam, and the steam boiler is the use of gas fuels, such as coal and natural gas to provide heat these. In addition, they use in the oil, but also very different.

The final step is to select which type of chain grate coal steam boilers currently on the market have the type of fuel boilers, electric boilers. Due to the current state for the "coal to electricity," the advocate, more companies may choose an electric boiler, but there are energy consumption, safety issues such as the traditional electric boiler, by contrast, the crown than conventional electric steam boilers boiler energy saving more than 30% compared to conventional steam boilers have increased security.

Learning materials heat boiler 1, the boiler is three safety accessories: water gauge, pressure gauge, safety valve. 2, the normal operation of the boiler water level is 0 ± 40mmH2O, the maximum does not exceed 0 ± 80mmH2O, the normal water pressure of 5.5MPa, to allow the fluctuation range of 4.5-6.0MPa, normal pressure boiler feed water temperature should be 105 degrees Celsius. 3, steam flow is not larger than the normal water boiler feedwater flow reasons, the measuring device instrument to do so. 4, the steam flow rate is less than the abnormal overheating damage reasons of water flow, water wall damage, damage to the economizer, the boiler is full of water, measuring device instrument to do so. 5, points on the furnace process CCP washed three times water gauge, pressures of 0.05-0.1MPa, 1.0MPa, 2.8MPa. 6, it is determined whether the normal water table and put into operation to see if the water level fluctuates slightly exemplar. 7, the boiler water pressure test and the test is divided into P overpressure test of two, when the water pressure P test, the boosting speed of not more than 0.35MPa 0.5MPa down rate does not exceed per minute. To the boiler water blowdown 8, the pressure in the boiler shutdown boiler water temperature drops below 80 degrees Celsius. 9, the position of each ordinary pressure test is hydrophobic doors: a door opening, the second door is closed. 10, the boiler-burner with a swirling-type and DC type two. 11, elemental analysis of coal with a composition: C, H, O, N, S, moisture, ash. 12, the main component of the blast furnace gas is: CO.'S time, nitrogen gas, blast furnace gas pressure is lower than 1500Pa, the user must reduce the amount of gas. Fire stop its pressure 1000Pa, working pressure 4000-8000Pa, the upper limit for the dangerous pressure 10000Pa, the lower limit is 2000Pa. 13, the main component of the coke oven gas: CO, nitrogen gas, coke oven gas pressure is lower than 1500Pa, must reduce the amount of gas, which pressure is 500Pa fire stop, working pressure 5000-7000Pa, the upper limit is 8000 Pa pressure the risk, the lower limit is 1500Pa . 14, the high, the main features of coke oven gas is flammable, explosive, toxic. 15, proximate analysis of coal with a volatile content, fixed carbon, ash and moisture. 16, boiler water circulation loop fault has stagnated, cycling back down the tube vaporization, soft drinks stratification. 17, the pulverized coal burning furnace radiation heat from a heat source of flame, high temperature flue gas convection heat. 18, the pulverized coal ignition and quick combustion conditions are sufficiently high temperature furnace, a sufficient amount of air mixed well, pulverized coal and air. Enough burn time. 19, ignition of pulverized coal into the combustion stage, the combustion stage, burning ember stage. 20, boiler mechanical rolling bearing does not exceed a predetermined temperature 80 degrees Celsius, the slide bearing does not exceed 40 degrees Celsius. 21, with factors affecting the steam load boiler water, boiler water salinity, pressure change, the vapor space of the drum height. 22, the principle of the steam separator drum gravity separation, inertial separation, centrifugal separation, separation of the water film. 23, the first ignition of the pulverized coal volatiles, fixed carbon is the latest ignition, the combustion of carbon is the longest. 24, steam soluble salt contaminated steam quality reasons, mechanical carryover. 25, the normal operation of the boiler drum water level in the glass tube than the water level high 50MM, when the water level in the steam table overall door leak, the water level high water table, the total gate leakage when the water level is low. 26, a method for enhancing heat transfer with a heat transfer coefficient is increased, raising the average temperature difference between the heat transfer, the heat transfer area is increased. 27, into the boiler furnace wall refractory layer, three-layer insulating layer and the sealing layer. 28, light blue flame blast furnace gas, as a bright golden yellow flame co-firing light yellow flame, coal, coke oven gas when the combustion gas as a combustion time. 29, the boiler by the "pot" and "furnace" composition, "pan" refers to a soft drink system is mainly composed of the drum, the downcomer, the header, waterwall, economizer, superheater composition; "oven" refers to a combustion system, a furnace, a burner, an air preheater composition. Calorific value 3.27GJ 30,1 tons of steam.
