Gas introduced gas szs fired steam boiler for sale steam boiler stop sign Profile: natural gas steam boiler is a steam boiler gas, natural gas steam boiler with natural gas as fuel, the combustion in the furnace heat put out by heating the pot water, and allowed to vaporized into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace temperature is increased and produce steam under pressure. Since the boiling point of water increases with increased pressure, the pot is sealed, the expansion of water vapor generated inside the pressure limited thermodynamic formed, strictly speaking, the steam boiler is heated in water at constant pressure saturated steam drum regasification water formed, is widely used as an energy source. Protection device: (1) protect the boiler water a boiler water level gauge plate supporting one to two, should always be compared with each other, inconsistent findings indicate that shall be corrected immediately. Class water level should be flushed, to determine their true level. While the water level comes electrode rod can accurately capture level signal to an alarm or a pump control. (2) steam pressure protection pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switches, other control lines or automatic control chain protection. Using pressure controllers and electrical contacts, the vapor pressure can overpressure alarm; single adjustable pressure controller or dual fire burning fire the actual operating pressure. Safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. (3) having a burner flame protection flame protection inlet means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged combustible residual gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. (4) self-locking power failure protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition. Editing boiler ignition procedures: 1. Check operation and (or) shift recording. 2, inspection, examination boiler, external. 3, check the main safety accessories.

Cause of the high energy consumption of electric szs fired steam boiler for sales through a lot of practice and testing, has made great progress in terms of a unified understanding of the design and practice getting closer and closer. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Currently, electric steam boiler heating operation and management, divided into two categories: professional management and unit housing construction sector management itself, the management level is generally low. Professional management in good condition, a few self-management units at a high level, in the most basic high energy consumption, low efficiency of state. In addition, widespread attention heating social benefits, but energy-saving consciousness, the application of new technology, new achievements of small, long-term stay on the extensive experience of management, not to the level of refinement of scientific management. For a long time, in the development plan, the electric heating steam boiler, a new, integrated planning joint planning of lack of awareness. Residential construction and use of all available space, scattered along the road of small hot water boiler room has become a matter of convenience. Form a compact electric steam boiler steam boiler and a small capacity electric power consumption is large electric steam boiler birth defects. Forming two small facts, and indeed closely related to the lack of unified planning, but also because of lack of planning and hard to avoid blindness. In the past for a long period of time, various safety considerations due to the heating of the design, the design heat load calculation results generally much larger than the actual required value. Therefore, the emergence of the world's more than a radiator, electric steam boilers, large pumps, large diameter of the situation, the mainframe carriage pull carts situation in the world, the phenomenon of low load, the flow is widespread. This is because the designers of the factors affecting the heating of insufficient knowledge, poor operations management such as heating, furnace workers low level of technology. They worry that heating is not hot enough, dare reduce the thermal load, resulting in equipment is still too large, creating a vicious cycle.

Recently, Xi'an, Shaanxi Province take minus coal, train control, dust suppression, government sources, prohibiting other measures, the air pollution caused by human factors reduced to very low, efforts to improve air quality in Xi'an winter. As of early November, Xi'an has cut 100 million tons of coal-fired, 15 high-ranked companies relocate or shut down.

In 2018, the Shaanxi provincial government issued a formal mandate to inform, Xi'an total of 140 million tons of coal to reduce the task, mainly around the Xi'an city government to cut electricity, central heating boilers Chaigai, urban and rural residents scattered coal and gas supply security in four areas of governance to carry out jobs. As of the end of October this year, has cut coal 1.015 million tons, completed 70.7% year plan. Built area of ​​29,419 catering units are the use of clean energy, outside built-up area 5196 catering units are to switch to clean energy.

Vehicle exhaust is one of the sources of atmospheric pollution. In order to strictly control the "black tail", environmental management staff at the three-ring along the line, passenger stations, farmers market, food stores and other black smoke high incidence of vehicle checkpoints set up 423-bit, low-speed vehicles investigated a total of 71,300 cases to go cut the line , black smoke car 7027 cases.

In the "anti-summer period", Xi'an continue to implement the motor vehicle limit line of control measures, and completed the 3255 update of pure electric buses put into operation, the completion rate of 102%. Newly started construction of public parking spaces 12,908, 86.1% completion rate. Investigate ChaoBiaoChe 3504.

In terms of the source rule, Xi'an cumulative Mopai "scattered dirt" Enterprise 21021 (including New West Ham), complete renovation 8163, completion rate of 38.8%; 15 high energy consumption, high emission enterprises to complete the relocation or shut down; 3399 Taiwan low nitrogen gas boiler to complete the transformation, the completion rate of 99.4%.

40 industrial enterprises complete control of volatile organic compounds, the completion rate was 88.9%; 26 224 restaurants and stalls point to install smoke purification facilities; 1259 spray paint auto repair business to complete in-depth treatment of exhaust gas, and all the installation of pollution control equipment independent meter; the Third Ring Road 336 gas stations outside the full completion of the transformation of tertiary recovery of oil and gas, and all the installation of pollution control facilities separate meter.

In terms of prohibiting, Xi'an completed summer crop straw comprehensive utilization area of ​​249.82 acres of mechanization, comprehensive utilization rate of 95.4%, exceeding the target task. At the same time, organized and implemented six acres and nine provincial and municipal straw utilization demonstration projects, compared with the provincial target increase of 12.5 percentage points; investigate and deal with the problem of black smoke burning from 457; 8 consecutive years of summer and autumn straw Jinshao to achieve "zero fire point" goal.

This year, the Xi'an handled a number of prominent air pollution problems. City of iron-fisted rule examination revealed a total haze to do all kinds of air pollution problems 1862, the city set up a team of 153 people to strengthen the supervision and inspection found problems common enterprise 6128, cross-check inspection found a total of 11,781 business problems. These issues are issued under the supervision of the list of issues to be reform.

Because of the particularity of the oil-gas boiler, from the initial construction preparation to the long-term acceptance of the project, there will be some problems to be paid attention to, and what should be complied with? Boilers need to follow the steps step by step to complete. What needs to be observed in the process? Oil and gas dual-use boiler installation before construction, first in accordance with the rules to first handle the boiler installation approval formalities, pending quality and technical supervision bureau approval after! Safety valve is an indispensable safety protection device in industrial boiler. Lever type safety valve can be often used, it can be divided into two types: single lever and double lever. Well, it was run in an industrial boiler. How does the lever-type safety valve work in the process? Why to carry out the air pressure test on the boiler? The lever type safety valve in industrial boiler is basically composed of valve core, seat and important lever, weight hammer and position limiting device. It acts on the valve core through the heavy torque of lever and weight hammer to flatten the pressure of steam. The main energy consumed in the operation of oil-fired boiler becomes fuel oil, so the quality of fuel oil will be directly related to the whole combustion state of the boiler, so how to choose fuel oil to supply to the oil-fired boiler? Generally divided into light fuel oil and heavy fuel oil two major categories. Fuel-fired boilers burn differentiated fuel oil The composition of the oil supply system will be different because of the different characteristics of the oil.
