Advantages of industrial steam boiler
1. The spiral furnace design
Increase the overall strength of the furnace,make compensation for the heat exchange and shrinkage automatically,avoid the in-perfection of welded sew crack due to the change of tube plate heating stress.Therefore,boiler has strong adaptability about various of fuel,for example,heavy oil,light oil,natural gas,city gas.
2. Improve heat transfer technology
Apply the technology of heat transfer from “the light of Harbin institute”.Adopt the design of efficient heat transfer screw thread pipe and optimize the smoke speed.The output and heat efficiency of boiler don’t decrease with the extend of operation time,thus achieve a compact structure with 10% overload capacity.
3. Climate compensation, on-demand heating technology
Considering to the outside temperature and users’ heat demand,boilers could control the water temperature in the support of heat source efficiency automatically so that we achieve the goal of on-demand heating and energy-saving heating.

Water treatment equipment Introduction
1. As we know, gas steam boilers need to configure water treatment equipment. However, some people do not know why to configure.let’s study together,what’s the specific role of water treatment equipment?
The water injected into boiler contains lots of calcium and magnesium and other cations. These cations are easy to form precipitate under heating at high temperature.The precipitate will attach to the inside of boiler.After long time operating, not only affect the thermal efficiency of boiler,but also damage the inside wall, thereby shortening boiler life and bringing economic loss to users.
2. In general, if boiler doesn’t equip the water treatment device, may bring some damage to the boiler as follows:
(1) Increasing fuel consumption volume.
(2) Shorten gas steam boiler life;
3. At last but not least,in daily boiler operation, you need to do:
(1) Detecting water quality of boiler regularly.
(2) Replacing the water treatment resin regularly, to ensure water treatment effect;
How to choose gas oil fired hot water boiler ?
1. Determine evaporation;
Selection of the boiler hourly steam production must be greater than the production needs of the steam, the production, the boiler can be 70% -100% load state operation, are the best running state;
2. Determine using pressure;
Boiler use pressure determined by the production process, selection, the boiler design pressure must be greater than the actual operating pressure to ensure that the boiler below the design pressure in the state of operation to ensure the safety of the boiler to ensure the operating results;
3. Determine the auxiliary equipment;
After confirm boiler evaporation and using pressure, you need to select the auxiliary equipment, what accessories equipment you choose, directly determine the running effect of boiler effect, also determine the price of boiler equipment;
