pump suitable for hot water boiler water circulation

2, meet environmental requirements, improve the environment.

If the gas fired boiler to boiler, boiler output in case of the same, C02 emissions can be reduced by more than 26%; S02 substantially zero; the NOx emissions by at least 33%; ash and soot are reduced to zero; Green environmental protection effect is remarkable.

3, reasonable program of boiler rehabilitation programs must be simple and easy to do: less investment and quick, short construction period. Accordingly, the content of the boiler according to the transformation in the transformation of the less the better, and can be taken to change only the furnace combustion apparatus, part of the basic structure of the transformation range as not to exceed the boiler body.

4, the reliability of the gas supply when the gas supply is not reliable, the fuel system may be provided. If you need to re-consider leaving room for coal-fired boilers, should select the appropriate way to meet the requirements of gas.

Input condensing gas boiler is in a volume of gas multiplied by the gas heating value (taking into account the influence of the air temperature, air pressure, humidity, heat calculation), different conditions of factors determine the calorific value of the gas has a high calorific value and low calorific value points.

Since 2017, located in Changchun City, Jilin Province to accelerate the governance of coal-fired boilers within the city out of small coal-fired boilers remediation process. Up to now, the work has achieved initial success.

15 in the city with 20 kilowatts and above the coal-fired generating units, 13 units have ultra-low emissions; city table 292 with 20 t steam / hour or more coal-fired boilers, emission standards have reached the count 253 male , accounting for 86.64% of the proportion of the boiler with; the city built area of ​​10 steam tons / hour small coal-fired boilers 2962 units, out of a total of 29553 units, up 99.7% out of proportion, the basic completion of the national requirements out of the task.

In order to further improve air quality, improve people's living environment standards index, Changchun City by expanding the ban on burning area, improve the standard phase-out of coal-fired boilers, plans to use two years of urban 20 tons of steam / h coal-fired boiler (kiln) furnace eliminated.

By the end of 2017, the city has eliminated 20 tons of steam / hour coal-fired boilers 964 units; at the same time to speed up the central heating and (expanding) network as well as the pace of clean energy promotion, provide for the transformation of the city's coal-fired boiler control a strong guarantee.

In recent years, Changchun City, adhere to the full implementation of coal-fired boilers governance, to improve ambient air quality in Changchun City has played a positive role. 2017, good days Changchun 276 days, compared with 2013, an increase of 35 days; heavy pollution days 10 days compared to 2013, reduced by 33 days; major air pollutants respirable particulate matter (PM10) and fine particles (of PM2.5) were 78 mg / m and 46 micrograms / cubic meter, respectively, 39.5% and 37.0% decrease over 2013.

How to select the right steam boiler? The newly established company will initially invest a lot of money to buy a steam boiler, often to buy what kind of steam boilers and worry in the case of funds not worry. So we simply talk about the issue to buy a steam boiler must be noted. The first item to note is rated evaporation, evaporation rated companies choose how much of their own business should be based on demand. For example, small companies need a large amount of steam was selected Rated evaporation of steam boilers, steam produced simply used up, it can only be a waste of money. For a lot of steam, but choose a small amount of evaporation of the boiler, the steam for less than the final result, it can only be used to add a new boiler or boiler, the final cost so much better than a place to directly select the appropriate high boiler. The second parameter is the thermal efficiency, a good addition to the rated boiler evaporation also need to have a large amount of high thermal efficiency, many companies chose to pursue cheap inefficient boilers will be very affordable in the short term, but over time will find efficiency low fuel consumption is also high boilers, steam production unit of fuel is very low, so that over time will be very loss. The third parameter is the rated steam pressure, not to say that as long as the boiler to produce steam on the line, with the steam vapor is still a difference, every business has a standard steam of each enterprise. Take the power plant, the steam turbine power plants require much pressure steam are all required, if the pressure is too high can damage the steam turbine plant, if the pressure is too low may not move at all with a steam turbine. Therefore, the appropriate choice of rated steam pressure is very important. The fourth parameter is the nominal steam temperature, steam pressure and rated Similarly, the selection of nominal steam temperature of the steam boiler must be based on the needs of steam equipment, steam equipment How high temperature steam, the steam boiler should choose appropriate rated steam temperature.

Explanation of Hot Water Heating Systems | Hunker

A gravity hot water heating system is the oldest and simplest system to heat homes. It is also the least efficient. In a gravity system, the circulation of water is due primarily to thermal and density differences between hot and cold water. As water heats, it expands, displacing the cooler and less dense cooler water throughout the system.
