After completion of the gas fire tube boiler fire tube condensing cleaning, be sure to use hot air to dry them, but not both for heating the furnace walls and other accessories, this is likely to have adverse consequences. Right way is to place an electric heater in the bottom of the gas boiler, heated.
Selection and classification of fuel gas thermal control system fuel gas fire tube boiler fire tube condensing 1. The boiler classification thermal control system (1) electric system for an electric meter instrument cluster system consists of relays, time relays, the relay program composed of program control and interlock system; manufactured by electronic control and intelligent series or digital instruments, measuring instruments display, sound and light alarm monitoring instrumentation and control system and other components. Electric instrumentation system design experience mature, the price is cheap, but it is difficult to achieve system redundancy, remote data transmission, maintenance is more difficult, more difficult to implement advanced control methods. Electric meter system is mainly used for small boilers, but the electronic control Applications for closed-loop regulation of decreasing almost been replaced by intelligent multi-function instrument, the following sections mentioned electronic control just want to take advantage of familiar industry and the series combination of a widely used instrument that time to explain the principles of the control system configuration and (2) programmable control system programmable control system is the core of programmable logic controller (PLC). Programmable logic controllers are widely used in the initial control, since the 1990s has increased the ability of process control, the programmable logic controller in the field of process control applications more widely.
Because of the particularity of the oil-gas fire tube boiler fire tube condensing, from the initial construction preparation to the long-term acceptance of the project, there will be some problems to be paid attention to, and what should be complied with? Boilers need to follow the steps step by step to complete. What needs to be observed in the process? Oil and gas dual-use boiler installation before construction, first in accordance with the rules to first handle the boiler installation approval formalities, pending quality and technical supervision bureau approval after! Safety valve is an indispensable safety protection device in industrial boiler. Lever type safety valve can be often used, it can be divided into two types: single lever and double lever. Well, it was run in an industrial boiler. How does the lever-type safety valve work in the process? Why to carry out the air pressure test on the boiler? The lever type safety valve in industrial boiler is basically composed of valve core, seat and important lever, weight hammer and position limiting device. It acts on the valve core through the heavy torque of lever and weight hammer to flatten the pressure of steam. The main energy consumed in the operation of oil-fired boiler becomes fuel oil, so the quality of fuel oil will be directly related to the whole combustion state of the boiler, so how to choose fuel oil to supply to the oil-fired boiler? Generally divided into light fuel oil and heavy fuel oil two major categories. Fuel-fired boilers burn differentiated fuel oil The composition of the oil supply system will be different because of the different characteristics of the oil.
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, fire tube boiler fire tube condensing 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.

Most non-condensing gas boilers are set up to run at about 82-86% efficiency. They are tuned to a lower combustion efficiency to avoid excessive flue condensation or damage to the boiler from the acidic condensate, and as a result give up even more source fuel heat to the atmosphere. Many new generation mod-con boilers with fire-tube heatOnline chat

In fire tube boilers, normally the heat transfer area of reference is taken as the outside surface of the tubes. So you use the outside diameter of the tubes for the calculation of the heatOnline chat
Steam locomotive, naval ships, and early models of cars, became the most sophisticated models of fire-tube boiler transportation in that period. As the name, the fire-tube boiler flows the hot gas to the water-coated tubes. Different pipeline designs from the various fire-tube boilers, are to maximize the heat absorption of the combustion gases.Online chat

Cost of boiler tube failures 9/4/2013 Steag O&M Company 7 The cost of boiler tube failures is comprised of three main components; the cost of the repair, the cost of start up oil to return unit to service, and the cost of lost production. A rule of thumb for repair costs of 200000 per day out of service+ cost of materialOnline chat
Meaning if the pressure drops on a fire tube boiler, it takes longer to come back up than on a similarly rated water tube boiler. Fire tube boilers typically have lower operating and maintenance costs, have easier access to the fire and water sides for inspections, and its much easier to replace tubes on a fire tube than a water tube.Online chat
