13 Ton water boiler

Gas-fired steam boiler is always the first contact with the lower drum half wall: in production, gas steam boiler operation often some thorny issues. Man of few words said, small series for you to sort out the boiler common problems and solutions, do not forget to share a small partner after learning finished oh.

Common forms and functions of household gas boilers What? Eyes looking at the winter to come, even a little bit cold in the morning, consider the division of winter heating, radiators and underfloor heating is still the most of my friends were like, whether it is considering radiator, is still considered to warm, in selected household heat source division, the boiler is not open around a big problem regarding a lot of terms is a boiler plate replacement, the machine casing, dual furnace, the furnace system, stainless steel, cast aluminum, is really incomprehensible. Today it is concerned about several different approaches boiler it only in the discussion of domestic gas boilers. Domestic boilers divided by FunctionClassification: dual furnace, the furnace system according to the preparation of a hot day separable way to catalog: telescopic, replaceable plate, Double-tube, coil type heat exchanger tank by combustion approach can be divided into: general type, condensation type, general type premix, premix condensing type to start from the beginning of the function classification, dual oven is heating / hot water dual-use furnace day, you can put the fantasy of dual-use furnace into two water heaters, a as heating, hot water a day served. Furnace system, the same day warm hot water to meet the needs of mining, but the furnace system, the system can not take direct hot day, will need to work a coil hot water tank to meet the day. Preparation of Hot Press day classification approach: the sleeve is more common board for boilers and boiler, Double-tube boiler tank and a heat exchanger coil boiler is not common. Tube boiler: the market still find many, operation principle is similar to gas water heaters, water enters the main heat exchanger, a boiler heating the board for a flame to obtain hot day. The so-called sleeve means its main heat exchanger, and the day of the hot water circuit loop approach Pipe sleeve tubular heating sleeve together, simple structure, low cost, low failure rate. Machine main heat exchanger casing of this disadvantage sleeve machine being characterized by a tubular sleeve so large pipe, the hot water is always heated days, when the winter heating hours, days open water, in the form of heating boiler is switched from the hot water to form days , out of the top section of the water temperature will be very high, there is a potential risk of burn people. And the structure of its resolution casing machine power is not too large, usually 18kw to 24kw. Board for boilers: boiler plate for comparison on the market now is the mainstream model, to change the boiler plate for heating hot water in the form of day, and adds a three-way valve and plate heat exchangers, the stability of such hot water progress, very comfortable with them. Premix condensation furnace: furnace premix combines the advantages of condensing premix boilers and recovery boiler flue gas, the thermal efficiency can reach about 98% -110%, with a minimum power boiler can reach about 2-5kw, improved energy efficiency . The premix condensing furnace is not directly applied in a boiler condensate return tank, but directly to the main heat exchanger of the boiler is increased, to increase the heat exchange area, so that the direct condensation of flue gas in the combustion chamber. Premix condensing furnace production process each manufacturer has a different, unlike the switch plate has been immobilized, but the fan frequency, accurate scheduling gas proportional valve, the main heat exchanger against corrosion that is required several standard accessories. Fume recovery boiler: low temperature into boiler return water condenser tank, high temperature flue gas also enters the condensate tank, the two heat exchange, heat exchange efficiency of the boiler can reach 97% As mentioned above, natural gas-fired comes mostly methane there is also a hydrogen sulfide, hydrogen sulfide from natural gas by deodorant. In the high temperature combustion of hydrogen sulphide attack sulfur dioxide, nitrogen in the high-temperature air generated nitrogen oxides, and the condensate tank will decrease the flue gas temperature, flue gas water vapor was separated in a liquid approach, reaction of water with sulfur dioxide and nitrogen oxides produced sulfite , nitrous oxide, sulfuric acid becomes about nitrate and corrosive, relatively poor corrosion condenser tank simple. Another problem is the problem of fouling of the furnace flue gas condensing recovery, because the presence of fouling by air, moisture condensed out of the box, can cause the dust adheres on the boiler main exchanger. General premix Oven: fan such boilers are converted, depending on the boiler board computer to schedule power boiler gas boiler intake air, the fan speed with the scheduling boilers, gas and air control in a very appropriate proportions into the combustion chamber combustion, thermal efficiency progress. This progress boiler thermal efficiency of the boiler, but do not attack the condensate water, but because the use of variable frequency fans, the price relative to the average furnace will be higher, but because of his air volume ratio and the amount of gas is very suitable, so nitrogen oxide emissions basically amount can be qualified, basically as long as this stove can get blue sky in the oven so that the general standard. With such machines because the use of air blower frequency, minimum power boiler can be made smaller.

How to compare gas boiler should be carried out and how the amount of gas savings? Gas boiler, it can be said that a common types of boilers, and in our daily lives, it can be seen, because it widely. That being the case, coupled with its product is the site, below, might be a good knowledge and understanding of this kind of boiler, so we also help with learning content, and then to use it properly. 1. coal-fired and gas-fired boilers, significant differences between them, what? Coal-fired and gas-fired boilers, these two common types of boilers, if to compare, then, the difference between them, mainly for: a difference: coal-fired boiler ash disposal site is required, but not gas-fired boilers needed because it is the fuel gas. Difference between the two: when coal-fired and gas-fired boiler is working properly, that water is about the same, but, on the secondary water gas boiler slag and dust, etc., can be saved.

Recently, Jinan City, Shandong Province People's Government issued and implemented the "2018 Beijing and Tianjin and the surrounding regions - 2019 autumn and winter tackling air pollution comprehensive management action plan" to inform the implementation of the program, requires the consolidation of ambient air quality improvement achievements, promote air quality continues to improve. On October 1, 2018 to March 31, March 2019, and all the city county fine particulate matter (of PM2.5) mean concentrations fell more than 2%, severe pollution and over several days up declining.

"Implementation plan" will be based on four construction industry, energy, transport and land use optimization adjustments to promote clean heating, public transferrin, enterprises mentioned standard upgrade, dust remediation, focusing on the consolidation of "scattered pollution" enterprise comprehensive rectification results, ruthless grasping diesel trucks, industrial furnaces and rectification of volatile organic compounds, heavy pollution to the implementation of the weather in autumn and winter peak load shifting production to strengthen joint prevention and control among regions, strengthen law enforcement supervision.

1, continued implementation of the total coal consumption control, strict implementation of national, provincial coal consumption reduction of about alternative work arrangements, and the development of alternatives seriously implement the Jinan City, the work reduction of coal consumption, coal consumption control tasks break down into individual counties, total coal consumption to achieve a steady decline. 2018, the city's total coal consumption control in less than 17.14 million tons.

2, effectively promote clean heating to the town (street) or the county as a unit as a whole. As of 2020, the city's pre-season heating living and improve the basic motivation for heating coal for alternative tasks, to develop a three-year implementation program to determine the annual task of governance. Taking into account the agricultural greenhouses, animal building bulk coal governance and to proceed with energy-saving buildings to improve energy efficiency. The county should proceed from reality, according to local conditions, reasonably determine the transformation of technical route, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, and actively promote the use of solar thermal and centralized biomass utilization; adhere to highlight focus, give priority to urban life and motivation for heating gas demand, priority to promoting the urban bulk coal cleared. Gas will adhere to the reform, to change the electric set, on the basis of priority to the protection of residents in 2017 has started "coal to gas," "coal to electricity" project on gas electricity, gas and new year according to the actual supply and heating period the ability to reasonably determine the residents' coal to gas, "" coal to electricity "households; insist on legislation after the break, substitution of gas for coal to electricity instead of coal and other alternatives, in the implementation of air power is not the case, the original heating facilities will not be removed. In accordance with national, provincial requirements, to complete the clean winter heating construction tasks 33000.

3, complete replacement of the bulk coal areas to be designated as high-pollution fuel combustion zone ban in accordance with the provisions, shall not be burning coal for use again. Severely crack down on sales of low quality coal combustion, to ensure the quality of coal used in line with national and local coal quality standards.
