gas fired skid mounted thermal oil boiler

Electric fired skid mounted thermal oil boiler is an indispensable heating gas in winter, that is, the most important electric boiler is not suitable to place combustible materials (paper, cloth and other combustible materials) around the boiler, which can reduce the occurrence of fire from the source. 2. Electric heaters do not have plugs, plugs forget to be unplugged and resistive wires are overloaded, or aging plugs and cables can also cause fires. 3. When using electric heaters, people should always be kept on the edges, and power plugs should be unplugged when they are not in use. Many people do not have the habit of unplugging the switches, but this will also give a fire a chance of fuelling. 4. If there is a sudden power outage, Unplug the heater to prevent incoming calls A fire broke out with a sudden increase in electric current.

01. Thermal control system classification of fuel-fired gas-fired boiler (1) Electric instrument combination system mainly consists of relay, time relay, program relay and so on, which consists of program control and interlock protection system; The monitoring and regulating system is composed of electric unit combination instrument or digital and intelligent series instrument, measurement and display instrument, acousto-optic alarm instrument and so on. The design experience of electric instrument system is mature and the price is cheap, but it is difficult to realize the redundancy of the system, data transmission and maintenance, and it is also difficult to realize the advanced control method. The electric instrument system is mainly used in the small boiler, but the electric unit combination instrument is used in the closed loop adjustment. The use of cases has been reduced year by year, almost replaced by intelligent multi-functional instruments, The electrical unit assembly instruments mentioned in the following sections are simply intended to illustrate the principle and composition of the regulation system using a series of instruments familiar to the industry and widely used in that era. (2) the core of programmable control system is programmable controller (PLC). The programmable controller has been widely used in logic control at first, and the ability of process control has been increased since 1990s, which makes the application of programmable controller in the field of process control more and more extensive.

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, fired skid mounted thermal oil boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.

The beverage plant needs steam in its beverage degassing ,sterilization, and packaging process. 3 ton steam requirement per hour came from beverage plant steam requirements in all process. Then, why there must be WNS series, any other choice here? WNS series steam capacity is from 2 ton to 10 ton, more suitable for lower capacity steam fired skid mounted thermal oil boiler. Of course, we also have SZS series which capacity is from 4 ton to 30 ton. To larger steam requirements, industrial gas oil fired power plant boiler is also available. If you want to use other gas fuels like lpg gas, bio-gas or liquid fuels like diesel oil, heavy oil, light oil, our WNS series steam boiler also can burn them. But, like our advanced engineer said before, each boiler is specialized for one designated fuel, this WNS series 3 ton steam boiler is manufactured to burn natural gas. Although it can burn other fuels, it can reach highest thermal efficiency when burning designated fuel natural gas.

75 ton CFB fired skid mounted thermal oil boiler

Fuel Flexibility: The most important advantage of the CFB boiler is the flexibility of firing a wide range of coal from 9500 to 25000 kJ/kg. CFBs can also burn a limitless number of other types of solid fuels, separately or mixed with coal. The limitations if any are only in the feeding and other mechanical equipment. The output capacity and steam parameters depend on the heating value of the fuel.

75 ton CFB boiler can use different types of solid fuels that include low quality coal, lignites, coal blends, bagasse in sugar plants, bark in pulp and paper mills, coal washery rejects in mines, petcoke and other bio mass products. Most of these fuels are seasonal, production or availability dependent. Mixing with coal or using coal when other fuels are not available gives an uninterrupted steam and energy supply.

1. Sulphur Dioxide removal: Firing high Sulphur coal requires the use of a Flue Gas Desulphurisation (FGD) plant to keep emissions within statutory limits. An FGD is a complicated plant that requires high capital investment and operational cost. In a CFB limestone addition in the furnace converts the SO2 to sulphates during the combustion and circulation which goes out with the ash. A CFB boiler costs less than a PC fired boiler with an FGD.

2. NOx Reduction: The combustion temperature in the furnace in a CFB boiler is considerably less than PC boilers resulting in lower NOx emissions. There is no additional requirement of separate NOx capturing devices which reduces capital investment.

3. Maintenance: Eliminating the pulverizer and pulverized coal piping reduces maintenance, related outages and equipment redundancy. A part of this saving is offset by higher maintenance due to erosion in pressure parts and furnace area, and maintenance of the refractory.
