oil fired fire tube steam boilers for sale
A boiler is an energy conversion device that outputs steam, high temperature water or an organic heat carrier with a certain amount of thermal energy. The boiler can be used for heating, hot water supplying, industrial steam supply, power generation, etc. Therefore, the application of boilers is very common. From the fuel, boilers can be divided into many types. The oil and gas boiler is a kind of boiler that uses natural gas, gas, oil, light oil, heavy oil, etc. The boiler uses gaseous fuel or liquid fuel, and the fuel can be delivered in the form of a pipe, which is convenient to use. With the strengthening of environmental protection and energy conservation awareness, many boiler manufacturing companies have also made achievements in these areas. Such as ZG boiler low nitrogen condensing oil and gas boiler to achieve ultra-low nitrogen emissions, and the boiler's thermal efficiency is high.
Gas boiler safe operating procedures: gas-fired boilers this kitchen I believe we are not unfamiliar fishes it. But this thing is not so easy, and sometimes improper operation causing very serious consequences, so the gas boiler rules is very important. That in the end this is how the specific operation of it, if you want to know, quickly told us with a look. 1. All personnel must be familiar with the operation of the boiler performance and safety knowledge of the boiler operating certificates. This post is strictly prohibited non-operating personnel. Duty should be strictly in accordance with the operating records and do a good job shift recording, the security situation and the device should shift change operation tests, carried out. When the shift to check the boiler is intact. 2. Boilers and safety accessories should be inspected, and in the period. 3.

At the end of 2018, Yantai City, Shandong Provincial People's Government Office issued the "Yantai Blue Sky win the Battle of three-year action plan implementation details," "rules" that: in principle, to new natural gas cogeneration and gas chemical projects. Details are as follows.
Continued implementation of the total coal consumption control, by 2020, the city's total coal consumption control in less than 24.19 million tons. Developed and implemented 2018-- 2020 coal consumption reduction alternatives work, the coal consumption Yajian task decomposition implemented in urban counties. Strict control of new coal project approval, approval, filing, encourage natural gas, electricity and other clean energy alternative to coal consumption. Censorship perfect substitute for coal, improve coal reduction coefficient replace coal utilization efficiency low industry. All new, revision, and expansion projects are implemented coal coal reduction alternatives, strict implementation of alternative sources and alternative proportions.
The development of special programs, out of shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance, the following priority out of 300,000 kilowatts to run at least 20 years of pure condensing unit, run over 25 years and Condensate Pumping Units still can not reach ultra-low emission standards for coal-fired units. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units.
Accelerate the phase-out of coal-fired facilities tea furnace built in the urban counties of the region, operating a stove, grain storage and drying equipment. The city's ban on new 35 steam tons / hour and coal-fired boilers. 65 steam tons / hour or more coal-fired boilers on the basis of complete transformation of the ultra-low emissions, with the transformation of the conditions to complete all energy saving. Out of coal-fired boilers heating pipe network coverage range. In the area where no cogeneration district heating conditions, a plurality of existing coal-fired boilers, and the like in accordance with the principle of building a large-capacity volume replacement coal-fired boilers.
The implementation of non-fossil energy doubling action plan, by 2020, non-fossil fuels in energy consumption should reach its goal provincial requirements, the city's wind power, solar power, biomass power, pumped storage power generation, nuclear power and other new energy and renewable energy power generation capacity reach 7.05 million kilowatts. Where the conditions of availability of resources, to encourage the development of biomass cogeneration county, increase renewable energy consumptive, improve social proportion of the total electricity consumption of renewable energy generation.
After electric fired fire tube steam boilers for sale shutdown, how to carry out maintenance in the long-term disabled electric steam boiler, furnace should pay great attention to external corrosion and maintenance problems. First, after power shutdown cooling steam boiler, the ash must be thoroughly cleaned and the heating surface fouling the upper grate, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. If the boiler shutdown a long time, after the complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. As for anti-corrosion maintenance methods inside the furnace shutdown, the shutdown Yaoan the length of time to be. In general, no more than one month shutdown maintenance wet available, more than one month should be taken to maintain dry. To note the following problems when a dry maintenance: desiccant boiler not in direct contact with the metal surface, may be mounted in a container such as the iron plate after the desiccant is placed, and a hole for shutting the other hand hole cover, valve steam, the water pipe change must cut lime powder should be replaced.
