Water Tube Boiler vs Fire Tube Boiler is comparison between two types manufacturers 20t diesel condensing boiler which is viewed from several aspects. Water tube and fire tube boiler is steam boiler classification which is categorized based on tube type.
How Principle gas steam manufacturers 20t diesel condensing boiler steam boiler temperature waste gas problem is simple automatic temperature control? Gas-fired steam boiler can not do simple automatic temperature control, the risk will occur. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Steam generated by the boiler and the pressure of the steam temperature of the heated liquid in strict correspondence relationship numerically. Small temperature changes cause large changes in pressure. And the temperature and reaction control with hysteresis characteristics with inertia, tends to achieve the desired detected temperature hysteresis value, even if the measures taken, the actual temperature will continue to change in the direction toward the original, it is easy to cause overpressure; while the evaporation of the boiler, the actual amount of steam pressure and a great relationship, if the constant temperature control, can cause large fluctuations in boiler pressure; furthermore the risk of boiler overheating caused by overpressure danger is far larger. Thus the steam boiler is usually a control outlet pressure, without controlling the temperature. Maintenance of gas steam boiler? Dry maintenance: Shutdown of the gas steam boiler discharge water released, the internal completely remove the dirt, rinse, drying Weihuo, not contacting the metal with lime. By weight quicklime, to the boiler volume 4 kilograms per cubic meter, then all manholes, hand holes, pipe valve closed, such as powdered lime broken into, i.e. to be replaced should be re-run the boiler quicklime removed. Gas-fired steam boiler shutdown after the release came out of water, the interior completely remove the dirt, rinse and refill the water has been treated, so that the water vapor exhaust out of the furnace, and then close all valves. Cold wet climates not care, so as not to damage the boiler furnace water freezes. Also repair and maintenance of steam boilers DZL series should strengthen the training and management of the fireman and the boiler, safe, stable and efficient operation. Gas-fired steam boiler waste water can be discharged directly do? Gas steam boiler in the absence of waste water pollution case can be directly discharged.
In fact, the manufacturers 20t diesel condensing boiler module does not refer to a type of boiler, it refers to a new type of boiler use. Small footprint by multiple parallel small boiler power together, joint control, used in some construction in the city's shopping malls, hospitals, hotels and other small areas. So why do these places have chosen to use "boiler module" mean?
"Coal to gas", "coal to electricity" is the trend in recent years of China's reform manufacturers 20t diesel condensing boilers, all regions are gradually improving. But because some areas coal to gas, coal to electricity-related project has not been completed, the pipeline can not be normal delivery of natural gas and electricity, but there can not ban the use of burning coal for heating, resulting in some of the people cold.
Under Thus, this year, Hebei Province, will carry out the inspection work cleaning heating dragnet, scheduled for November 1 to 10, requires each village and household dragnet inspection, the gas supply, power supply is not guaranteed to get the premise not allowed to first dismantle heating stoves.
Inspection team is more than 2,000 people drawn from the province's environmental protection system, divided into 120 large groups, each group of sub-1-2 large counties (cities, districts), take the main city limits off-site inspection, cross-check each other, such as thorough investigation way, a comprehensive understanding of coal to gas, coal to electricity and clean coal work on behalf of the double security for the situation.
Wherein, the village 500 (cell) is not less than 20% of households checks; 500 villages and above (cell) checks no less than 10% of households. The main inspection five aspects, including: gas supply, power supply security, security for the clean coal and distribution, development of contingency plans, etc. under extremely adverse weather conditions. In gas supply, power supply is not guaranteed under the premise, the focus in advance to see if the removal of heating stoves situation.
Environmental Protection Department official said earlier this year in northern clean heating to proceed from reality, insist on the need for constant, the gas will change to ensure that clean heating and warm winter are guaranteed.
