7 mw gas fired hot water boiler for hotel
For a large hotel, 7 mw fired hot water boiler for hotels are a good choice for supplying hot water for the entire hotel bath. Oil and gas hot water boilers are widely used in this kind of occasion. Recently, CBM once again exported to a wns oil and gas hot water boiler in Mexico to provide demand for a hotel. Gas fired hot water boilers have a short production and installation cycle, which saves the company some unnecessary costs due to excessive time. The wns produced is small in size and does not occupy too much space. It is easy to install and has a high degree of automation. This saves many labor costs, plant costs and learning costs. And oil and gas hot water boilers use natural gas, oil, biogas and other fuels as fuel, which is clean, does not need to store fuel, low noise, and no dust is very suitable for providing hot water for the hotel.
What if there is wear and tear in the natural gas boiler? Detailed inspection is the key, as is fuel management. According to the operation condition and time of natural gas boiler, we can plan reasonable wear inspection. When using fuel, we strictly control the granularity of coal and limestone. The size of bed material should be strictly controlled. Boiler waste should be disposed of. The waste residue of the boiler must be treated before it can be discharged. Natural gas boilers should be installed where heat is used, easy to install. The hot pipe should not be too long. It should have a good insulation. The pipe shall be tilted properly from the hot water outlet to the end. The water supply source shall be equipped with a control valve. To discharge exhaust gases, the chimney of the natural gas boiler should extend to the outside and the outlet should be 1.5 to 2M higher than that of the boiler. If we want to reduce the influence on the water wall tube, we can adjust the air pressure and air volume properly, and effectively reduce the wear of the water wall. Check time is usually standby or downtime. Items to be examined include wall wear, furnace sealing and smoke leakage. In case of wear and tear, repair and welding are required to ensure the normal operation of steam boiler. Generally speaking, before combustion of natural gas boilers, fossil fuels, fossil fuels and bed and circulating materials should be filled in the combustion chamber at wind speed and strength. And stiffness of the air convection under full integration. Furnace bottom air device, inner core area upward. The movement in the outer ring region flows downwards along the water wall of the furnace, thus prolonging the residence time of the coal particles in the furnace. Mineral particles, a large number of ash powder and smoke contain a large number of fly ash particles, these continue to lead to rapid wear of water-cooled wall tube, make wall thickness wear thin, resulting in wear.
Some of the causes boiler efficiency impact of fuel domestic hot water have been carried out impressive work in the coal to natural gas, the choice of fuel 7 mw fired hot water boiler for hotel, a very large cut discharge dust pollution, together with nitrogen oxides and other dangerous gases have also been oppression. Fuel efficiency is an important measure of hot water boiler, well that is that we begin to study the influence of some of the root causes of fuel efficiency hot water boiler. Through the investigation of the relevant departments, hot water boiler fuel consumption is derived from these two main places: the proportion of non-standard combustion air and exhaust full heat loss. Exhaust heat loss can be reduced less fuel hot water boiler installed in the chimney waste heat recycling terminal is provided, or in the selection of more leading condensing boiler system. Combustion air ratio is not sufficiently standard statistical noncompliant: conventional hot water boiler with a fuel combustion machine ejector, formed air-fuel ratio can not be flexibly adjusted. 70% of the oil hot water boiler with a mechanical blower burner, causing the root causes of non-standard air-fuel ratio in the following areas: air-fuel ratio is not the most important criteria are divided into two cases: when the airflow exceeded, there will be extra rich low-temperature air is heat conduction, resulting in increased fuel consumption of hot water boilers, hot water boiler fuel efficiency decreases; when the airflow is not enough, not sufficient to ignite the situation will cause the emergence hot water boiler fuel efficiency.
Harbin Thermal Power Co., the main city of Harbin is the largest cogeneration business, the company bear the city's heating area of 24 million square meters, to provide heat supply for more than 400 agencies, enterprises and 140,000 residents. Currently, the company is actively respond to the latest environmental standards introduced in China, the group mobilized up and down, stepping up technological innovation, upgrading environmental protection facilities, the project is expected to complete upgrading coal-fired boiler at the end of this year.
Harbin Thermal Power Co., the existing five boilers for heating and power generation: where to cogeneration units No. 7,8,9, and the other two hot water boilers. No. 9350 MW units which since 2017 was completed and put into operation, has achieved ultra-low emissions standards during construction. 7, No. 8 is 300 MW units were built in 2005 and 2006, these two units of environmental transformation began in 2013. Harbin Thermal Power Co., according to the latest environmental requirements, environmental upgrading facilities. First, soot emissions transformation, the introduction of advanced electric bag filter, followed by addition of sulfur, in addition to the transformation of nitrate, new burners in addition to the low nitrogen oxides of nitrogen, a wet desulfurization technologies in addition to sulfur dioxide. After four consecutive years of continuous transformation, 7,8 units in 2017, all the transformation is completed, achieve ultra-low emissions standards. For the two 116 MW hot water boiler was built in 2013, it has long been included in the transformation plan. Earlier this year preparatory work has been completed and environmental transformation has entered the bidding process in mid-October to start construction, completed renovation project at the end of December.
