A wet-back structure hot water boiler, the water returning mouth symmetrical design (double inlet) for quick connection installation; hot water boiler mechanical and electrical integration, compact size and reasonable transportation is very convenient. The top of the hot water boiler with a vent to the atmosphere, the interior is not under pressure, boiler work at atmospheric pressure, there is no risk of explosion, the complete elimination of security risks.
This is our first collaboration with fast boiler, professional and caring service fast boiler's impressed us. From pre-sales advice to after-sales guidance, every step is very careful and thoughtful. They provide wet-back structure hot water boiler performance is also very good, and effectively improve the level of our heating units. --customer feedback
Heating an area of 10,000 square meters, it requires much gas boiler our front-line consultants told us that many users in consultation with the heating gas boiler, first ask "me so much heating area, several tons of boiler you can meet ah? "and so, today, we have to 10,000 m2 heating area, for example, the selection of several tons of gas boiler is a brief introduction. Under normal circumstances, the factors affecting the selection of an integrated gas heating boiler, heating area of 10,000 square meters, probably need about 3.6MW wet-back structure hot water boiler capacity. But this is an ideal situation, 3.6mw gas hot water boiler conversion at approximately equal to 5 tons of hot water boiler. Fast boiler production of one ton boiler can basically meet the heating area of 10,000 square feet, which is very good data, after all, the greater the tonnage of the boiler, the boiler, the higher the price. If in the arctic regions, and heating the building belongs to the old building, the use of gas-fired boiler capacity will increase, and may even take up to 7 tons, 8 tons of hot water boiler in order to protect the user wants to reach room temperature. Factors Affecting gas heating boiler tonnage selection: 1, the user is expected to reach room temperature; 2, - heating the length, width, height, and other structural features of the presence or absence of the room partition; 3, heating the target material which type of structure (whether saving, how insulation performance); 4, characteristics and other areas where the heating target. (Eg the same building, in the south and northeast of the required size of the boiler will be very different).
We calculated according to heat a ton of water was heated from 15 deg.] C to 50 deg.] C are required. Require heat: Q = 1000kg × (50 ℃ -15 ℃) × 1kcal / kg ℃ = 35000kcal conventional gas boiler thermal efficiency of the gas boiler ordinary gas consumption is now about 90% in about 1 cubic meters of gas heat is 8500kcal / m³. Then, 1 cubic meter of natural gas available heat: 8500kcal / m³ × 90% = 7650kcal / m³. 35000kcal calculated according to above mentioned 1 ton of water was heated from 15 deg.] C to 50 deg.] C needed, tons of hot water heated air consumption: 35000kcal ÷ 7650kcal / m³ = 5.2m³. Now on the market price of natural gas at 3.5 yuan float, each one ton of hot water needs heating costs: 3.5 × 5.2 = 18.2 yuan. Premix gas boiler air consumption side of the fast introduction of gas boiler, by the addition of premix combustion technique, fuel combustion more fully, and the condensing means located in the tail of sufficiently high temperature flue gas discharged from a boiler flue gas re-use, two portions of the heat the secondary absorbent melted, the thermal efficiency of up to 108%. Similarly, we follow one cubic meter of natural gas heat is 8500kcal / m³ is calculated. Then, 1 cubic meter of natural gas available heat: 8500kcal / m³x thermal efficiency of 108% = 9180kcal / m³. 35000kcal calculated according to above mentioned 1 ton of water was heated from 15 deg.] C to 50 deg.] C needed, tons of hot water heated air consumption: 35000kcal ÷ 9180kcal / m³ = 3.812m³. The current natural gas prices per cubic meter of float about 3.5 million, 1 ton of hot water is required per heating costs: 3.5 × 3.812 = 13.342 million. The data obtained is calculated in the case where the fuel gas boiler fully utilized, the practical application of heat loss will be part of a more or less gas, from many angles, so when calculating the actual gas boiler air consumption, calculated in this way it may be more in line with the value of the user's actual situation. By contrast to conventional gas boiler and gas consumption premix condensing gas boiler, we can see that under the same circumstances, and adding premix condensing gas boiler technology to save more fuel. Therefore, if you are facing difficulties to buy gas boiler, you may wish to go into the formula, and more to help you determine the level of the boiler.
