To understand the advantages and disadvantages of hot blast stove and hot water stove, we should start from the working principles of the two boilers. The hot water boiler can increase the indoor temperature by burning hot water, circulating hot water, heat dissipation, etc. General purpose (radiators, floor heating pipes, water heating air conditioners are generally used for heating in families, enterprises and institutions). Tianjin Gas fired hot blast stove The hot blast stove can increase the indoor temperature by heating the air. Generally, a hot channel wind belt is required. It is generally used for workshop, breeding, planting and special heating or drying. Most areas in northern China are cold, such as the three northeastern provinces, Inner Mongolia, Xinjiang and other cities. The colder temperature is more than minus 40 degrees Celsius. There are hot water boilers and steam boilers for heating. Its disadvantage is that it is afraid of circulatory system failure or power failure. small-scale Gas fired hot blast stove manufactor Once the power failure exceeds two to three hours, if the insulation is not good, the pipeline will freeze. The heating of hot blast furnace is not frozen, and the temperature can be set. It can save 40% energy than hot water heating and 50% energy than steam boiler heating. This comparison is practical. The hot blast stove does not need to apply for a use certificate, the steam boiler and pressure hot water boiler need to apply for a use certificate, and the functional department also needs to carry out annual inspection every year, but also has to bear the cost.

Biomass boilers need green new energy. Compared with other boilers, biomass boilers have the following four major advantages: one boiler is multi-purpose, and can cook, boil water, and bathe while heating. Strong conversion system, low starting heat transfer temperature and fast heat transfer speed. Tianjin Gas fired hot blast stove Low installation cost, safe heating: the equipment is universal, without changing the original heating equipment, and the pipes and radiators are universal. Water circulation is used to achieve a wide range of heating materials, which will never be exhausted. It can be taken everywhere (such as rice husks, corn stalks, rice stalks, wheat). Safety and environmental protection: low working pressure, cooking, water boiling, bathing, heating, etc., and it is also suitable for burning boilers, greenhouse heating Large area heating and small and medium-sized hotels can be used all year round without seasonal restrictions. small-scale Gas fired hot blast stove manufactor The reason why the ignition of biomass boiler is difficult is that the stable small fire signal cannot be established, which is caused by the failure of the small fire detector to detect the fire normally. The flame detector for small fire is ionization type flame detector, which requires a contact area with the flame, stable flame size, and gas pressure controlled within a strict range.

As is known to all, the boiler using sensible heat of various waste gases and waste heat after waste incineration as heat source is called waste heat boiler, also called waste heat boiler. Therefore, the country advocates vigorously developing waste heat utilization, energy conservation and emission reduction, which plays a positive role in protecting energy and improving the quality of human living environment. Tianjin Gas fired hot blast stove In the design of waste heat boiler, how to reasonably divide the temperature range is the basis for reasonably arranging the heating surface of waste heat boiler and making maximum use of waste heat. Under the condition of a given exhaust gas temperature at the inlet of the waste heat boiler, there are two requirements for the exhaust gas temperature. One is to limit the exhaust gas temperature, which is required to be within a reasonable range; The other is that the exhaust gas temperature is not limited, requiring greater use of waste heat. small-scale Gas fired hot blast stove manufactor In either case, for medium and low temperature waste heat utilization, the narrow point temperature difference directly affects the evaporation capacity of the waste heat boiler and the layout of the heating surface. Narrow point temperature difference, also known as node temperature difference, is a small temperature difference between evaporator outlet flue gas and heated saturated water vapor during heat exchange. With the change of narrow point temperature difference, the relative total heat exchange area, relative evaporation capacity and relative exhaust gas temperature of the waste heat boiler also change.

When using stainless steel storage tank, cracks appear on the head. If it is not handled in time, it will be dangerous, and how to handle this situation will be explained. Tianjin Gas fired hot blast stove Firstly, the cracks in the stainless steel tank can were removed by polishing. After grinding, pits that do not need repair welding and do not affect the grading shall be formed within the allowable range. Otherwise, repair welding shall be carried out. The position of surface crack defect shall be determined by surface penetration defect detection, and the welding repair shall be completed. The horizontal gas tank shall be repaired, and the weld and surrounding materials shall be repaired. After that, argon tungsten arc welding shall be used for repair welding. small-scale Gas fired hot blast stove manufactor Tungsten argon arc welding shall be adopted for welding repair. It is suitable for back welding or skip welding, small size multi-layer and multi pass non rotating welding to avoid overheating of the weld. Water cooling measures are adopted. The defects of stainless steel storage tanks shall be removed by grinding with angular grinding wheel with conical grinding rod. Note that the abrasive grains of the grinding wheel should be perpendicular to the crack length. If the defect is deep, crack stop holes shall be drilled at both ends of the defect to prevent the crack from expanding with the grinding process. According to the inspection, in the stainless steel storage tank with primary side inspection, there are cracks at the head welds, and these defective welds have different edge bite degrees. Do not panic when the stainless steel tank can has cracks. The oil tank works. The above measures can be taken to solve this problem.
