Take a closer look at the scrapping conditions. Do not include other organization names in the content. The bidding format is according to the bidding documents, and the missing content can be added, and the original can not be reduced (written without can not be reduced). The stamped part is clear. How to seal the label, see clearly. There are differences.

If you don't just look at the area, you can also look at the height and length of the room, and how many turns there are.
-
Dongbao heating stove, heating can also be installed, as well as underfloor heating. It's all warm and it's not expensive.
You can add a layer of insulation board to the house, the insulation effect is very good in winter, and the cost is not high.

Hunan rural housing Xie 180 square meters of four bedrooms and two living rooms, want to install coal-fired boilers and radiators, what is the cost? How to choose the main equipment? Is there a suitable company to recommend? Thank you!
-
Most of the small earth heating stoves of 120 square meters can be brought up, but don't buy too cheap ones to use.
-
The Döle stove is a good choice.
-
120 stoves, 100 ordinary radiators Good radiators can reduce ......The stove is bigger and the effect is better, after all, the house is high.

The boiler can be heated with an area of 3,000 square meters.
Algorithm: boiler calorific value of 200,000 kcal per hour is equivalent to calorific value of 200,000 kcal per second 3600 seconds joules = 233 kJ seconds, equivalent to power 233 kilowatts; In the north, the thermal index is taken as 60 watts of square meters, then 233,000 watts of 60 = 3,883 square meters. Reserve some amount to round up to 3,000 square meters.
-
As far as the housing structure in the north is concerned, generally 1 ton can heat 6,000 square meters, 1 ton can be 600,000 kcal, and large calories can be flattened.
-
4 tons of hot water pot to furnace heating area of 32,000-40,000 square meters.
source hot water boiler.
Performance characteristics:1The thermal efficiency of hot water boiler is more than 77%, which is higher than the standard of "General Technical Conditions for Industrial Boilers".
2.The boiler is quickly installed and shipped out of the factory, and after it is used at the site, it can be operated by installing valves and instruments, drums, induced draft fans, flue gas pipes, dust collectors and water circuits, etc., and has the characteristics of fast starting and ignition.
3.The boiler is easy to install and move, which can save a lot of infrastructure investment.
4.Class II bituminous coal with low calorific value of 17750J kg, volatile matter and ash content.
Scope of application: Atmospheric hot water boiler series is the ideal first choice for heating, bathing, air conditioning and domestic hot water in various industries such as enterprises, institutions, hotels, schools, etc.
-
A 1-ton hot water boiler can supply 8,000-10,000 square meters, and a 4-ton hot water boiler can supply 32,000-40,000 square meters.
-
Different regions have different heating surface solutions, and one square meter needs 80-150 kcal.
Causes of boiler coking: 1. Coking is related to ash melting point. If the installation angle of the burner is skewed, the burner itself is defective, the burner is too large, and the pulverized coal gas flow is deflected and rubbed against the wall, which will often lead to serious coking of the boiler. >>>More
1.Choose a reasonable amount of oxygen for operation.
2.Select a reasonable furnace outlet temperature to optimize the combustion adjustment test of the boiler, and discharge smoke from the furnace. >>>More
The pressure-bearing parts of the boiler include all the parts of the "pot", that is, all the steam and water systems. >>>More
Here is the 30-man squad for Spain:
Goalkeepers: Casillas (Real Madrid), Reina (Liverpool), Diego López (Villarreal), David De Gea (Atletico Madrid), Valdés (Barcelona). >>>More
The main functions of the steam drum are: the connection hub of the three processes of working fluid heating, evaporation and superheating to ensure the normal water circulation of the boiler; There is a steam-water separation device and a continuous sewage discharge device inside to ensure the quality of boiler steam; There is a certain amount of water, a certain heat storage capacity, and the change rate of steam pressure is slowed down; There are pressure gauges, water level gauges, accident water discharge, safety valves and other equipment on the steam drum to ensure the safe operation of the boiler. >>>More
