Diesel Oil Fired Vertical Small Steam Boiler
9.4MW YQW gas-fired thermal oil heater for clean-energy industryThermal oil heater is a kind of new heat energy equipment with low pressure and high temperature, playing an important role in various industries. Huagang Gas Group is a sino-foreign joint venture enterprise, which established by Kunlun Energy Company Limited and Huabei Oilfield Company. The company is engaged in natural gas, liquefied petroleum gas, blast furnace gas and so on. Due to the stringent quality requirement for pipeline gas in China, all natural gas needs to be decarbonized and desulphurized. A high-quality diesel fired vertical small steam boiler is one of the key equipment for the productive process. With the development of global environmental policy, the demand of clean energy is growing with each passing day. Huagang Gas Group has carried out public bidding to purchase one set of thermal oil heater to meet the production need. Relying on rich experience and powerful comprehensive technology strength, ZOZEN won the bid and provided 9.4MW YQW series thermal oil heater for them. The heat exchange surface of the thermal oil heater adopts multi-loop round coil tube structure, which features high security and sufficient heating surface. The waste heat boiler, air pre-heater and economizer are installed on the tails of the thermal oil heater to effectively improve the thermal efficiency (The thermal efficiency of ZOZEN thermal oil heater can reach up to 95%). Moreover, this kind of thermal oil heater adopts perfect running control and safety monitoring device, which can control working temperature strictly and guarantee the safe operation.
120 ton coal fired CFB boiler performs high capacity and good efficiency. And petrochemical corporation also needs high pressure on its oil related products manufacturing. Blind coal or anthracite, is a hard natural coal that burns slowly and gives intense heat. Coal fired cfb boiler with blind coal which has features of low combustible content, high ignition point, low burning temperature and high explosion concentration. 120 ton coal fired diesel fired vertical small steam boiler with cfb system is another light spot product in ZG Boiler. Nowadays, after conquered the above problems step by step, blast furnace gas, converter oven gas, coke gas can be used as the firing fuel which are applicable for both mixed and unmixed burning type of a series of product in the range of 75t/h –260 t/h. Moreover, 120t/h anthracite boiler won many technology prize in China. This boiler is capable of peak adjustment under basic and varying load, can adapt to the install characteristic (eg. heat value, pressure, flow rate) of fuel and has favorable adjusting performance under varying cases. The type of boiler is widely applied in metallurgic industrial field with around 65 units of sales performance till now.
Gas-fired diesel fired vertical small steam boiler safe operation Tidbits gas steam boiler safe operation Tips 1. The operator should be familiar with the structure and principles of the furnace and the production of basic requirements for thermal equipment, and constantly sum up experience in practice, control coal thickness, so that the full combustion reduce chimney smoke, protect the equipment in a safe, efficient operation. 2. The new oil furnace or restart long home, gas steam shall dehydration stage heating requirements. 3. export oil temperature should be set below 280 ℃, when the oil temperature exceeds 200 ℃, should pay more attention to temperature, oil temperature should slow down, only non-oil change and over-temperature operation. 4. close contact with production, timely and slow down the oil temperature, while meeting production requirements, taking oil lower, will help extend the life of gas and steam energy savings. The normal oil level: the lower tank oil level is low, high-high oil groove. This ensures that the emergency shutdown when cold oil replacement system and prevents air from entering the pipe. When the high slot in a low oil level should start to replenish gas steam injection pump. 6. The circulation pump is allowed outage in the operation of the burner, when the pump is failure or power outage, Fan stop, depending on oil temperature and take appropriate emergency measures: rapid opening valve 7, the cold head tank oil up through the furnace coils to the low tank. 8. Coal and wet coal hearth fire or discharge out of the furnace, non-water washed pouring furnace. These measures should be completed within 3 to 5 minutes, to prevent the high oil temperature coke deposits other accidents. 9. normal shutdown, the oil temperature should be reduced to below 100 ℃, stop the pump before. 10. When the outlet pressure differential below the set value, the induced draft fan should outage. Then there is a fault system, feedback should be immediately removed or, if necessary, should pressure fire outage. 11. fireman should stick to their posts, do a good job operating records and shift work, and regular inspection and maintenance equipment.
The latest was informed Tongling Municipal People's Government issued the "Notice on Tongling City to win the Battle of Blue Sky embodiment", as follows.
First, deepen industrial pollution control
Continuing to promote a comprehensive industrial pollution discharge standards, increase penalties and excessive joint disciplinary efforts, not discharge standards of the enterprise to suspend for rectification according to law. Implementation covering all stationary sources of emissions permits enterprise system, before the end of 2020 to complete the trade provisions of the license issued discharge permit management directory.
Carry iron and steel, cement, nonferrous metals, thermal power, coking, casting and other key industries and ports, shipping, coal-fired boilers fugitive emissions investigation, the establishment of management accounting, before the end of 2019 to complete the material (including waste) transportation, handling, storage, transfer and process fugitive emissions such as in-depth treatment.
Second, the continued implementation of the total coal consumption control, strict implementation of coal consumption reduction instead. By 2020 the city's coal consumption control in less than 13 million tons of coal accounts for the proportion of total energy consumption to decline further. Strict implementation of new coal projects coal reduction instead. Added support for the power industry outside of iron and steel, chemicals, nonferrous metals and other industries coal projects, the implementation of coal consumption reduction of 1.5 times alternatives. Increased focus on bulk coal remediation efforts. High-pollution fuel combustion zone ban bulk coal sales all clear.
Third, the implementation of the "coal to gas" and "electricity instead of coal." Strengthening the capacity of natural gas supply security, promote glazed tiles, casting and other industries natural gas instead of coal gasification project, orderly implementation of coal-fired facilities from coal to gas. Combined with regional and industry energy characteristics, and actively promote the implementation of "electricity instead of coal" in the field of industrial production, transportation, agricultural production, living and so on.
Fourth, continue to strengthen the supervision of the boiler. Consolidate the results of rectification of small coal-fired boiler, make sure the rebound does not occur, a citywide ban on new 35 tons of steam per hour and coal-fired boilers. Increase efforts to eliminate small coal-fired boilers. Dynamically updated list management coal-fired boiler, built-up area City 35 tons of steam per hour coal-fired boilers by the end of 2019 total phase-out or implementation of clean energy alternatives; retention of six chemical companies 2 130 tons of steam per hour of coal-fired boilers to complete all energy saving and ultra-low emissions transformation.
Fifth, strengthen the bulk coal governance. Strictly implement the "Interim Measures for commercial coal quality management" (National Development and Reform Commission Order No. 16) and technical standards for coal-fired boilers, in-depth implementation of bulk coal remediation crucial action, and strictly implement the ban on burning areas prohibit the use of high-polluting coal for fuel measures. To strengthen the management and control of coal-fired coal. Ongoing monthly coal quality sampling, and promote enterprises to increase coal-fired coal reform efforts.
